Inherited prothrombotic risk factors and cerebral venous thrombosis. (1/2331)

Fifteen patients with cerebral venous thrombosis were ascertained retrospectively. Their case notes were reviewed, and stored or new blood was assayed for factor V Leiden (FVL) mutation, prothrombin gene mutation 20201A, and 5,10 methylene tetrahydrofolate reductase (MTHFR) C677T mutation. A clinical risk factor was identified in 13 patients--the oral contraceptive pill (5), puerperium (1), HRT (1), mastoiditis (1), dehydration (1), lumbar puncture and myelography (1), carcinoma (1), lupus anticoagulant (2). In addition, two patients had the FVL mutation and five (one of whom also had the FVL mutation) were homozygous for the MTHFR mutation. The latter showed a higher than expected frequency compared to 300 healthy controls from South Wales (OR 3.15.95% Cl 1.01-9.83). No patient had the prothrombin 20201A mutation. Two patients died and three had a monocular visual deficit following anticoagulation (13) or thrombolytic (2) treatment, but there was no association between the presence of a primary prothrombotic risk factor and outcome. These results confirm the importance of investigating patients for both clinical predisposing factors and primary prothrombotic states.  (+info)

Aetiologies and prognosis of Chinese patients with deep vein thrombosis of the lower extremities. (2/2331)

Deep vein thrombosis (DVT) of the lower extremities is not frequently encountered in Oriental patients. We investigated its aetiology and prognosis in 143 patients (65 males, 78 females), presenting to the National Taiwan University Hospital over 4.3 years, diagnosed by colour Doppler ultrasonography. Swelling and pain of the lower extremities were the most frequent presenting symptoms. The left femoropopliteal veins were more frequently involved than other parts of the lower extremities. In these patients, malignancy with or without intravenous catheterization was the most frequent cause (39 patients, 27%). Other common aetiologies included coagulopathy (29 patients, 20%), immobilization (24 patients, 17%) and catheter-related (13 patients, 9%). No definite aetiology could be determined in 37 patients (26%). During follow-up, 27 patients (19%) died, mostly with malignancy. Pulmonary embolism was noted in 16 patients and was not significantly directly related to death. Compared to similar studies in Caucasian patients, there were significant differences in the aetiology of DVT, with malignancy and coagulopathy more common in these Chinese patients.  (+info)

Venous duplex scanning of the leg: range, variability and reproducibility. (3/2331)

Despite the many studies on venous haemodynamics using duplex, only a few evaluated the normal values, variability and reproducibility. Therefore, the range and variability of venous diameter, compressibility, flow and reflux were measured. To obtain normal values, 42 healthy individuals (42 limbs, 714 vein segments) with no history of venous disease were scanned by duplex. To determine the reproducibility the intra-observer variability was measured in 11 healthy individuals (187 vein segments) and the inter-observer variability in 15 healthy individuals (255 vein segments) and 13 patients (169 vein segments) previously diagnosed with deep venous thrombosis. Of the 714 normal vein segments, 708 (99%) were traceable, including the crural veins. Of the traceable vein segments, 675 (95%) were compressible and in 696 (98%) flow was present. Of the 42 common femoral vein segments, in 25 (60%) the reflux duration exceeded 1.0 s, but in the other proximal vein segments the reflux duration was less than 1.0 s (95% confidence interval 3.0-10.0). With the exception of the distal long saphenous vein, in the distal vein segments the reflux duration was less than 0.5 s (95% confidence interval 3.5-8.2). The coefficient of variation of the diameter measurements ranged from 14 to 50% and that of the reflux measurements from 28 to 60%. The kappa-coefficient of the inter-observer variability in the classification of compressibility measurements in the patients was 0. 77 and that of the reflux measurements was 0.86. This study shows that almost all veins were compressible in healthy individuals, except the distal femoral veins. In healthy individuals the duration of reflux of the proximal veins was less than 1.0 s and in the distal veins it was less than 0.5 s. The inter-observer variability of the reflux and compressibility measurements in the patients was good.  (+info)

G20210A mutation in prothrombin gene and risk of myocardial infarction, stroke, and venous thrombosis in a large cohort of US men. (4/2331)

BACKGROUND: A single base pair mutation in the prothrombin gene has recently been identified that is associated with increased prothrombin levels. Whether this mutation increases the risks of arterial and venous thrombosis among healthy individuals is controversial. METHODS AND RESULTS: In a prospective cohort of 14 916 men, we determined the prevalence of the G20210A prothrombin gene variant in 833 men who subsequently developed myocardial infarction, stroke, or venous thrombosis (cases) and in 1774 age- and smoking status-matched men who remained free of thrombosis during a 10-year follow-up (control subjects). Gene sequencing was used to confirm mutation status in a subgroup of participants. Overall, carrier rates for the G20210A mutation were similar among case and control subjects; the relative risk of developing any thrombotic event in association with the 20210A allele was 1.05 (95% CI, 0.7 to 1.6; P=0.8). We observed no evidence of association between mutation and myocardial infarction (RR=0.8, P=0.4) or stroke (RR=1.1, P=0.8). For venous thrombosis, a modest nonsignificant increase in risk was observed (RR=1.7, P=0.08) that was smaller in magnitude than that associated with factor V Leiden (RR=3.0, P<0. 001). Nine individuals carried both the prothrombin mutation and factor V Leiden (5 controls and 4 cases). One individual, a control subject, was homozygous for the prothrombin mutation. CONCLUSIONS: In a large cohort of US men, the G20210A prothrombin gene variant was not associated with increased risk of myocardial infarction or stroke. For venous thrombosis, risk estimates associated with the G20210A mutation were smaller in magnitude than risk estimates associated with factor V Leiden.  (+info)

Low-molecular-weight heparin in outpatient treatment of DVT. (5/2331)

Patients with a diagnosis of acute deep venous thrombosis have traditionally been hospitalized and treated with unfractionated heparin followed by oral anticoagulation therapy. Several clinical trials have shown that low-molecular-weight heparin is at least as safe and effective as unfractionated heparin in the treatment of uncomplicated deep venous thrombosis. The use of low-molecular-weight heparin in an outpatient program for the management of deep venous thrombosis provides a treatment alternative to hospitalization in selected patients. Use of low-molecular-weight heparin on an outpatient basis requires coordination of care, laboratory monitoring, and patient education and participation in treatment. Overlapping the initiation of warfarin permits long-term anticoagulation. Advantages include a decreased incidence of heparin-induced thrombocytopenia and fewer episodes of bleeding complications. Future clinical trials evaluating the safety and efficacy of low-molecular-weight heparin in the treatment of complicated deep venous thrombosis will further define appropriate indications for use and strategies for outpatient management.  (+info)

Right atrial bypass grafting for central venous obstruction associated with dialysis access: another treatment option. (6/2331)

PURPOSE: Central venous obstruction is a common problem in patients with chronic renal failure who undergo maintenance hemodialysis. We studied the use of right atrial bypass grafting in nine cases of central venous obstruction associated with upper extremity venous hypertension. To better understand the options for managing this condition, we discuss the roles of surgery and percutaneous transluminal angioplasty with stent placement. METHODS: All patients had previously undergone placement of bilateral temporary subclavian vein dialysis catheters. Severe arm swelling, graft thrombosis, or graft malfunction developed because of central venous stenosis or obstruction in the absence of alternative access sites. A large-diameter (10 to 16 mm) externally reinforced polytetrafluoroethylene (GoreTex) graft was used to bypass the obstructed vein and was anastomosed to the right atrial appendage. This technique was used to bypass six lesions in the subclavian vein, two lesions at the innominate vein/superior vena caval junction, and one lesion in the distal axillary vein. RESULTS: All patients except one had significant resolution of symptoms without operative mortality. Bypass grafts remained patent, allowing the arteriovenous grafts to provide functional access for 1.5 to 52 months (mean, 15.4 months) after surgery. CONCLUSION: Because no mortality directly resulted from the procedure and the morbidity rate was acceptable, this bypass grafting technique was adequate in maintaining the dialysis access needed by these patients. Because of the magnitude of the procedure, we recommend it only for the occasional patient in whom all other access sites are exhausted and in whom percutaneous dilation and/or stenting has failed.  (+info)

Evaluation of lidocaine as an analgesic when added to hypertonic saline for sclerotherapy. (7/2331)

PURPOSE: The efficacy of sclerosing agents for the treatment of telangiectasias and reticular veins is well established. The injection of these agents is often associated with pain, and it is not uncommon for sclerotherapists to include lidocaine with the sclerosants in an attempt to reduce the pain associated with treatment. However, there are concerns that this may reduce the overall efficacy of the treatment because of dilution of the sclerosant. Patient comfort and overall outcome associated with treatment using HS with lidocaine (LIDO) versus that using HS alone was compared. METHODS: Forty-two patients were prospectively entered into the study and randomized blindly to sclerotherapy with 23.4% HS or 19% LIDO. Study subjects and treating physicians were blinded to the injection solution used. Injection sites were chosen for veins ranging in size from 0.1 to 3 mm. Photographs of the area to be treated were taken, and the patients rated their pain. They were then observed at regular intervals for four months, and clinical data was collected. Thirty-five subjects completed the full follow-up period, and photographs of the injected area were taken again. Three investigators blinded to the treatment assignment then evaluated the photographs and scored the treatment efficacy according to a standardized system. RESULTS: In the HS group, 61.9% (13 of 21) patients rated their pain as none or mild, whereas 90.5% (19 of 21) of patients in the LIDO group had no or mild discomfort. This difference is significant, with a P value of.034. There was no difference in the overall efficacy of treatment between the two groups. The groups had similar rates of vein thrombosis and skin necrosis. CONCLUSION: Although lidocaine is often used with sclerosing agents, there are no previous reports in the literature to evaluate its effectiveness in reducing the pain experienced by the patient. In this study, patients receiving LIDO experienced significantly less discomfort at the time of injection than patients who received HS alone. There were no differences in the effectiveness of treatment or in the incidence of complications between the two groups.  (+info)

Relief of obstructive pelvic venous symptoms with endoluminal stenting. (8/2331)

PURPOSE: To select patients for percutaneous transluminal stenting of chronic postthrombotic pelvic venous obstructions (CPPVO), we evaluated the clinical symptoms in a cohort of candidates and in a series of successfully treated patients. METHODS: The symptoms of 42 patients (39 women) with CPPVO (38 left iliac; average history, 18 years) were recorded, and the venous anatomy was studied by means of duplex scanning, subtraction venography, and computed tomography or magnetic resonance imaging. Successfully stented patients were controlled by means of duplex scanning and assessment of symptoms. RESULTS: The typical symptoms of CPPVO were reported spontaneously by 24% of patients and uncovered by means of a targeted interview in an additional 47%. Of 42 patients, 15 had venous claudication, four had neurogenic claudication (caused by dilated veins in the spinal canal that arise from the collateral circulation), and 11 had both symptoms. Twelve patients had no specific symptoms. Placement of a stent was found to be technically feasible in 25 patients (60%), was attempted in 14 patients, and was primarily successful in 12 patients. One stent occluded within the first week. All other stents were fully patent after a mean of 15 months (range, 1 to 43 months). Satisfaction was high in the patients who had the typical symptoms, but low in those who lacked them. CONCLUSION: Venous claudication and neurogenic claudication caused by venous collaterals in the spinal canal are typical clinical features of CPPVO. We recommend searching for these symptoms, because recanalization by means of stenting is often feasible and rewarding.  (+info)

Background: The aim of this study was to investigate whether routine complete blood count parameters such as the mean platelet volume, red cell distribution width, white blood cell and platelet counts, and novel inflammatory biomarkers such as platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio could be used as the predictors of acute deep vein thrombosis.. Methods: This retrospective study included a total of 68 patients (29 males, 39 females; mean age 55.2±1.6 years; range, 22 to 80 years) with acute lower extremity deep vein thrombosis and 34 healthy controls (15 males, 19 females; mean age 52.8±2.5 years; range, 21 to 77 years) without acute lower extremity deep vein thrombosis between March 2016 and August 2018. Demographic and clinical characteristics of the participant and laboratory data including complete blood count parameters were recorded. Univariate and multivariate analyses were used to identify significant predictors of deep vein thrombosis.. Results: Demographic and ...
Hypercoagulable states and triggering factors (surgery, trauma, immobilization, pregnancy, and use of oral contraceptives) are associated with an increased risk for deep venous thrombosis of the lower extremities. In contrast, risk factors for deep venous thrombosis of the upper extremities have not been identified. Objective: To evaluate the prevalence of hypercoagulable states and triggering factors in patients with primary deep venous thrombosis of the upper extremities. Design: Frequency-matched case- control study. Setting: Hemophilia and thrombosis center at a university hospital Patients: 36 patients who had primary deep venous thrombosis of the upper extremities, 121 patients who had primary deep venous thrombosis of the lower extremities, and 108 healthy controls. Patients who had deep venous thrombosis of the lower extremities and study controls were frequency- matched by age, sex, geographic origin, and social status with patients who had deep venous thrombosis of the upper ...
Sometimes varicose veins result in further complications like superficial vein thrombosis. These veins rest near the surface of the skin, mostly in the legs. Symptoms of superficial vein thrombosis include tenderness in the leg, pain and redness in the skin. In patients with varicose veins, even a mild injury can result in inflammation. This inflammation makes the blood clot root more firmly to the wall of the vein. In a way, superficial vein thrombosis is different than deep vein thrombosis as these veins lack surrounding muscles, which can cause a blood clot to move. Therefore, there is a lower chance embolism ...

TY - JOUR. T1 - How should we determine length of anticoagulation after proximal deep vein thrombosis of the lower limbs?. AU - Siragusa, Sergio. AU - Siragusa, Sergio. PY - 2009. Y1 - 2009. N2 - The current approach for deciding the duration of vitamin K antagonist (VKA) treatment after an episode of venous thrombo-embolism (VTE) is mainly based on the characteristic of the index event (3 months or longer in case of unknown/persistent risk factors, 3 months or less in case of removable causes). However, the length of anticoagulation should be tailored on the patients risk for recurrent thrombosis as well as for bleeding, but such time for decision is often unclear and the optimal duration of VKA remains debatable. The presence of persistent residual vein thrombosis and increased D-dimer levels after stopping therapy are predictors for recurrent deep vein thrombosis (DVT). Management strategies based on these parameters have been demonstrated to optimize the decision for VKA duration, as they ...

The incidence of deep venous thrombosis is 0.6/1000 habitants and when symptomatic its diagnosis by duplex scan has 100% sensitivity and 98% specificity. The aim of this study was to evaluate the findings of the duplex scan in patients with clinical suspicion of deep venous thrombosis. 239 consecutive outpatients (59.2 ± 18.6 years, 164 female) were evaluated by duplex scan. According to symptoms 101 (42.3%) were related to the right lower limb; 113 (47.3%) to the left lower limb; and 25 were related to both lower limbs. Forty-eight patients presented a normal duplex scan. Venous thrombosis was found in 117 patients (0.49; CI 0.43-0.55): 75 with deep venous thrombosis (DVT), 22 with superficial venous thrombosis (SVT) and 20 with both DVT and SVT. Other pathologies were found in 74 patients. Among patients with DVT the most involved veins were below the knee. Among patients with SVT, 20 (47.6%) showed progression to the deep venous system: 9 (45%) by perforans veins; in 6 by saphenous-femoral junction
Venous thromboembolism (VTE) refers to two different conditions: deep vein thrombosis (DVT) and its potentially fatal acute complication, pulmonary embolism (PE)5. A venous thrombosis is a blood clot (thrombus) that forms within a vein. Most often, it develops in the deep veins of the leg or pelvis and is known as deep vein thrombosis. An embolism occurs if the clot, or a part of it, breaks off from the site of formation and travels through the circulatory system. If the clot lodges in the lung a potentially fatal condition, pulmonary embolism, occurs.6. VTE is estimated to be the third most common cardiovascular disorder after coronary heart disease and stroke.7 Over 750,000 venous thrombotic events are estimated to occur annually in six major EU countries (France, Germany, Italy, Spain, Sweden, UK) 8, and over 900,000 events occur annually in the US.9 Figures for the six European countries show that venous thrombotic events kill more people than AIDS, breast cancer, prostate cancer, and ...

The process of recanalization of the veins of the lower limbs after an episode of acute deep venous thrombosis is part of the natural evolution of the remodeling of the venous thrombus in patients on anticoagulation with heparin and vitamin K inhibitors. This remodeling involves the complex process of adhesion of thrombus to the wall of the vein, the inflammatory response of the vessel wall leading to organization and subsequent contraction of the thrombus, neovascularization and spontaneous lysis of areas within the thrombus. The occurrence of spontaneous arterial flow in recanalized thrombosed veins has been described as secondary to neovascularization and is characterized by the development of flow patterns characteristic of arteriovenous fistulae that can be identified by color duplex scanning. In this review, we discuss some controversial aspects of the natural history of deep vein thrombosis to provide a better understanding of its course and its impact on venous disease.. ...
In the present series, 8.4% of patients were found to have splanchnic vein thrombosis at evaluation. This proportion probably underestimates the true incidence of splanchnic vein thrombosis during end stage cirrhosis. Indeed, a significant proportion of patients with extensive thrombosis may not have been referred to our centre because they were not considered as suitable candidates for transplantation and therefore were not taken into account for analysis. None the less, eight of 230 (3.2%) patients who did not have thrombosis at evaluation developed thrombosis while on the waiting list. Importantly, the majority of these patients (6/8) only had partial portal vein thrombosis. Although pretransplantation Doppler-US screening was performed at three month intervals, nine additional patients were found to have thrombosis at the time of surgery. Again, eight of these nine patients had only partial thrombosis and transplantation was technically feasible in all cases.. Multivariate analysis showed ...

For some people long haul flights or regular flights in general are a main part of business or even personal life, and with this comes the risk of developing DVT (Deep vein thrombosis). Deep vein thrombosis (DVT) is a blood clot that forms in the deep veins of the leg. Deep vein thrombosis in the thigh carries a risk of pulmonary embolism. This is when the clot that was formed in your leg, moves from your leg and into your pulmonary artery and also the lungs, and if large enough can even eventually cause death.. The symptoms of deep vein thrombosis (DVT) may include pain and tenderness in the leg, pain on extending the foot, the skin is red and warm and swelling of the lower leg, ankle and foot,..

We studied the risk of recurrent thrombosis and death in a large cohort of 224 patients with a first venous thrombosis of the upper extremity. The cumulative incidence of recurrence after 2 years was 8% (95% CI, 4% to 12%), and the incidence rate of recurrence was 43.2 per 1000 person-years (95% CI, 27.8 to 58.7). Women had a 2-fold higher recurrence risk than men and appeared to have, contrary to men, a decreased survival in the absence of malignancy. There appeared to be an increased risk of recurrence for patients with a first nonsubclavian vein thrombosis and for patients with a BMI ≥25 kg/m2. Patients with a first thrombosis resulting from a CVC had a decreased risk of a recurrent event.. After discontinuation of treatment (n=163), the 2-year cumulative incidence was similar at 7% (95% CI, 2% to 12%), which was also similar to the incidences found in 2 previous smaller studies (4.2% and 7%) that included only patients after discontinuation of treatment.5,17 The incidence of recurrence in ...

Deep vein thrombosis - what is it? Deep vein thrombosis of the lower extremities is a disease in which blood clots (blood clots) form in the lumen of deep veins. Due to the formation of blood clots, the normal flow of blood is disturbed, and this leads to blockage of blood vessels. Symptoms of deep vein thrombosis do not appear immediately, only in case of an increase in thrombus. If there is a separation of a clot of a blood clot, shortness of breath, pain in the chest area, hemoptysis may occur.

Deep vein thrombosis, commonly called DVT, refers to blood clots that form in the deep veins of the extremities. Most of the time these clots occur in a persons legs, but they can develop in the arms too. Deep vein thrombosis alone is not fatal, but if the DVT turns into a pulmonary embolism it can cause sudden death.. Signs & Symptoms of Deep Vein Thrombosis There are several common signs that a person may have developed a DVT. A person may present with all of the symptoms or a mix of them. In some cases however, there are very few signs at all. Recognizing these signs early and seeking medical attention immediately are key to preventing a fatal pulmonary embolism from developing.. ...
Evidence-based recommendations on rivaroxaban (Xarelto) for treating deep vein thrombosis (DVT) and preventing recurrent DVT and pulmonary embolism
Background: Contrast venography remains the standard for diagnosing suspected lower extremity deep venous thrombosis (DVT). Compression ultrasonography for diagnosing proximal DVT has been successfully implemented in many clinical settings. Its use in detecting distal lower extremity DVT is debatable. Current guidelines recommend follow-up compression ultrasonography five to seven days after an initial negative result because distal lower extremity DVT may propagate into proximal veins. This may not be effective because a small number (1 to 2 percent) of repeat images are positive for thrombus propagation, and patients may not return for their repeat procedure. For this reason, the ability of a single whole-leg compression ultrasound image to diagnose lower extremity DVT has been evaluated. Johnson and colleagues conducted a systematic review and meta-analysis to determine the risk of venous thromboembolism in patients for whom anticoagulant therapy was withheld following a single negative ...
The incidence of cerebral venous thrombosis (CVT) is increasing, partly due to an improvement in the diagnostic techniques [1]. growing tendency for neurologists to consider them for treatment of CVT. A few case series have been published supporting the security and efficacy of these drugs in CVT cases [8-11]. More recently, the results of one randomized controlled trial (randomized controlled trial of the security and efficacy of dabigatran etexilate vs. dose-adjusted warfarin in patients with cerebral venous thrombosis [RESPECT CVT]) were presented at World Stroke Congress in 2018 [12]. The trial randomized 120 patients to either dabigatran or warfarin and showed no recurrence of venous thrombotic events and a small number of major bleedings in both arms. Before the results of RESPECT CVT were made available, we conducted a multicenter prospective, observational study to evaluate the security of NOACs compared to warfarin in patients with CVT. Data was collected from October 2016 to October ...

In this study, we found that the risk of a first venous thrombosis is 2-fold higher in men than in women once female reproductive risk factors for venous thrombosis are taken into account. These results were found in all age categories and were not affected by adjustment for body mass index and smoking or by the exclusion of participants with malignancy.. To the best of our knowledge, this is the first study to assess the risk of first venous thrombosis in men compared with women with and without reproductive risk factors separately. We found a relative risk of 2 when comparing men with women without reproductive risk factors, which indicates that the intrinsic risk of venous thrombosis is higher in men than in women. Until now, this higher intrinsic risk of venous thrombosis in men has mostly been noted in recurrence research.10-14 Studies have shown that men have a 2-fold higher risk of recurrent venous thrombosis than women.10-14 It was hypothesized that this could be explained by a reduction ...
Blood clotting is significant for our health. Also called coagulation, it prevents excessive bleeding when a blood vessel is injured. Whenever a blood vessel is injured platelets and proteins in our blood work together to form a clot over the injury and stop bleeding. According to vascular surgeons in Hyderabad, such a clot gets naturally dissolved after the injury is healed. However, in some cases, clots can form on the inside of the vessels that may or may not be due to an injury and may not dissolve naturally. Such clots can become dangerous which need medical attention. One such condition is Deep Vein Thrombosis (DVT).. What is Deep Vein Thrombosis?. Deep vein thrombosis (DVT) is a vascular condition that occurs due to blood clots formed in one or more of the deep veins in your body. It may show symptoms like swelling and pain or may not show any symptoms. This condition is usually seen in the legs but can occur in the thigh, pelvis, and arms as well. It can become serious, result in severe ...
Call your doctor right away if you have these DVT symptoms, especially if they appear suddenly: Call 911 or go to an emergency room right away if you notice leg pain or swelling and: If you have a blood clot and it breaks free, it could travel to your lungs. © 2005 - 2019 WebMD LLC. Call your doctor or get medical help right away if you develop any of these signs or symptoms of bleeding: If you take XARELTO® and receive spinal anesthesia or have a spinal puncture, your doctor should watch you closely for symptoms of spinal or epidural blood clots. I noticed that my lower right leg was just ballooned out about twice its size. If a doctor thinks you have DVT, you should be referred to hospital within 24 hours for an ultrasound scan. Certain medicines may increase your risk of bleeding. Deep vein thrombosis (DVT) is a clotting disorder that usually begins in the legs. This can find DVT in your pelvis and thigh.

While these clots most often develop in the lower legs or thighs, they may appear in the upper body, such as the arms or other locations in the body. Deep vein thrombosis is a risk after any major surgery, but patients who have surgery of the legs or hips are at higher risk.. Deep vein thrombosis can pose a serious threat to health. Pieces of a clot can break off and travel through the bloodstream to the lungs. This is called a pulmonary embolism and can be fatal soon after it occurs. Deep vein thrombosis can also block blood flow in the veins, causing the blood to pool. This can cause swelling, pain, and permanent damage to the leg called post-thrombolic syndrome.. ...
It is said that the early identification of a disease can help in eradicating it at the first stage itself. This way, the body will be less exposed to possible threats that might have occurred at a later stage. Deep vein thrombosis is a serious condition where blood starts to clot in a vein deep inside your body.. Many people often tend to overlook the symptoms of deep vein thrombosis and dismiss the symptoms of pain or skin turning to red or blue as a cause of insect bite. But knowing deep vein thrombosis symptoms can help in the easy identification of this disease. A few symptoms are discussed here.. ...

we assessed the role of pharmacological prophylaxis in the prevention of PICC line related thromboembolic complication.. Methods: We reviewed the electronic medical records in our center to collect data about Patients who had an ultrasound at the site of PICC line insertion and age ranges from 18-65 years old. The final population sample size consists of 227 patients who was included in the retrospective analysis. The sample population mean age was 57.3 ±18.5. Female constitutes 145 (64 %), and males were 82 (36%). 140 patients (62%) had ultrasound confirmed venous thrombosis at the site of PICC line insertion. About 50% of the patients had either deep venous thrombosis (DVT) or both DVT and superficial venous thrombosis, 28% had superficial thrombosis only, and 38% had no thrombosis. Pharmacological DVT prophylaxis in the form of either heparin or ...
Isolated distal deep vein thrombosis (DVT), also known as calf DVT, represents up to 50% of all lower limb DVT in ultrasound series and is therefore a frequent medical condition. Unlike proximal DVT and pulmonary embolism (PE), which have been extensively studied and for which management is well standardized, much less is known on the optimal management of isolated calf DVT. Recent data arising from registries and non-randomized studies suggest that most distal DVTs do not extend to the proximal veins and have an uneventful follow-up when left untreated. This data had some impact on the international recommendations which recently stated that ultrasound surveillance instead of systematic therapeutic anticoagulation might be an option for selected low-risk patients. However, robust data arising from randomized studies are scarce. Indeed, only five randomized trials assessing the need for anticoagulation for calf DVT have been published. Many of these trials had an open-label design and were ...

Background: Patients with cancer who undergo surgery about the hip are at increased risk for the development of deep vein thrombosis. We implemented a program of chemical and mechanical prophylaxis to prevent this problem. This study was performed to assess the effectiveness of that program. Methods: Eighty-seven consecutive patients with an active malignant tumor who underwent hip replacement surgery at our institution over a two-year period were included in the study. All patients were treated with intermittent pneumatic compression devices. Seventy-eight patients received anticoagulants, and nine did not. Postoperative surveillance for proximal deep vein thrombosis was routinely performed on all patients with duplex Doppler ultrasonography. Results: Four patients had proximal deep vein thrombosis, and one patient, who did not receive anticoagulation, had a nonfatal pulmonary embolism. The use of prophylactic low-molecular-weight heparin (dalteparin) was associated with a 4% rate of proximal ...
Critically III patients have multiple risk factors for deep vein thrombosis and pulmonary embolism. The majority of patients with pulmonary embolism have a lower extremity deep vein thrombosis as a source of origin. Pulmonary embolism causes a high mortality rate in the hemodynamically compromised individual. Awareness of risk factors relative to the development of deep vein thrombosis and pulmonary embolism is important for the critical care nurse. Understanding the pathophysiology can help guide prophylaxis and treatment plans. The therapies, from invasive to mechanical, all carry risks and benefits, and are weighed for each patient. The advanced practice nurse, whether in the direct or indirect role, has an opportunity to impact the care of the high risk patient. Options range from teaching the nurse who is new to critical care, to teaching patients and families. Development of multidisciplinary protocols and clinical pathways are ways to impact the standard of care. Improved delivery of care ...

Although thrombosis complication is rare after arthroscopic meniscus surgery, deep vein thrombosis and pulmonary embolism can be fatal. The associated risk factors and whether anticoagulant prevention after arthroscopic knee surgery is necessary have not reach consensus. Here we present a case of deep vein thrombosis and pulmonary embolism after a common arthroscopic meniscectomy. The patient had no risk factors except ipsilateral leg varicose veins. She present swell at knee and calf from postoperative 3 weeks, and developed dyspnea, palpitation, and nausea on 33th day, pulmonary embolism was confirmed with CT angiography at emergency department. After thrombolysis and anticoagulation therapy were administered, the patient improved well and discharged. And the intravenous ultrasound confirmed thrombosis of popliteal vein and small saphenous vein. Who dont have common risk factors for venous thromboembolism.

Data on adult transplants in the United States during the Model for End-Stage Liver Disease (MELD) era through September 2016 were reviewed. We constructed and validated a scoring system composed of routine, readily available clinical information to predict the development of incident PVT at 12 months from transplantation listing. A total of 66,568 liver transplant candidates were dichotomized into 2 groups to construct (n = 34,751) and validate (n = 31,817) a scoring ...
Though home treatment is an option in some cases, most patients suffering from deep vein thrombosis will require hospitalization, as most will have additional risk factors that will require more monitoring than home care can provide. Deep vein thrombosis is typically treated by breaking down the clot with thrombolytic agents. Patients are then given anticoagulants to prevent the formation of new clots and pulmonary embolism. For patients that cannot undergo anticoagulant treatment, an inferior vena cava filter can also be used to reduce the occurrence of pulmonary embolism. However, this treatment is viewed only as a temporary measure to prevent the more life threatening pulmonary embolism. For medical and surgical inpatients, prevention is key and most hospitals will use a combination of anticoagulants, thromboembolic deterrent stockings, and intermittent pneumatic compression devices to prevent deep vein thrombosis from occurring. For travelers, as well as those patients susceptible to deep ...

IMPORTANCE: Deep vein thrombosis (DVT) isolated to the calf veins (distal to the popliteal vein) is frequently detected with duplex ultrasonography and may result in proximal thrombosis or pulmonary embolism (PE).. OBJECTIVE: To evaluate whether therapeutic anticoagulation is associated with a decreased risk for proximal DVT or PE after diagnosis of an isolated calf DVT.. DESIGN, SETTING, AND PARTICIPANTS: All adult patients with ultrasonographic detection of an isolated calf DVT from January 1, 2010, to December 31, 2013, at the Vascular Laboratory of the University of California, Davis, Medical Center were included. Patients already receiving therapeutic anticoagulation and those with a chronic calf DVT, a contraindication to anticoagulation, prior venous thromboembolism within 180 days, or diagnosis of a PE suspected at the time of calf DVT diagnosis were excluded. Data were analyzed from August 18, 2015, to February 14, 2016.. EXPOSURES: Intention to administer therapeutic ...
Upon transfer to the university hospital, the patient was continued on intravenous heparin. The patients condition improved initially but was later complicated by heparin-induced thrombocytopenia, which required the use of low molecular weight heparin. The patients condition further worsened with impairment of vision requiring lumboperitoneal shunt and stopping of anticoagulation treatment. Anticoagulation treatment was subsequently restarted, but Mr A developed cerebellar hemorrhage, which resulted in his demise.. Our patient lacked peculiar demographics of patients with idiopathic intracranial hypertension. Also, initial negative noncontrast CT scan was not sufficient and is often misleading in patients with cerebral venous thrombosis. We document a rare case of cerebral venous thrombosis in a 77-year-old man with initial normal noncontrast brain CT. Although rare, cerebral venous thrombosis can present in an elderly man with recent history of otitis media and with negative brain CT. This ...

Sheila, I am sorry to hear of your husbands condition. I had portal vein thrombosis following a resection for HCC, it was approximately 15cm in size. I was treated with Warafin (which is a blood thinner) to breakup the thrombosis and that worked just fine. I am a little confused as to why they cant treat the thrombosis. Do you have the information on the location of the HCC lesion and its size? I have survived 2 rounds with HCC in the last 5 years; I had hep-c (contracted during the Vietnam war) which I went through treatment for and now am undetectable, advanced stage of Cirrhosis, then HCC with 2 tumors first time treated with liver resection, then the Portal Vein Thrombosis, and then 1 tumor a 2nd time treated with a RFA procedure. I receive MRIs now every 6 months to help with early detection of another recurrence. I am 62 years of age. I would suggest seeking out a Comprehensive Cancer treatment center ( I go to the University of Michigan Hospital) and to obtain a 2nd opinion. Keep the ...

The prevalence of deep venous thrombosis in patients with advanced cancer is unconfirmed and it is unknown whether current international thromboprophylaxis guidance is applicable to this population. We aimed to determine prevalence and predictors of femoral deep vein thrombosis in patients admitted to specialist palliative care units (SPCUs). We did this prospective longitudinal observational study in five SPCUs in England, Wales, and Northern Ireland (four hospices and one palliative care unit). Consecutive adults with cancer underwent bilateral femoral vein ultrasonography on admission and weekly until death or discharge for a maximum of 3 weeks. Data were collected on performance status, attributable symptoms, and variables known to be associated with venous thromboembolism. Patients with a short estimated prognosis (,5 days) were ineligible. The primary endpoint of the study was the prevalence of femoral deep vein thrombosis within 48 h of SPCU admission, analysed by intention to treat. This ...
The optimal duration of anticoagulation after recurrent venous thromboembolism(VTE) is poorly established [1,2]. Recent studies suggested that D-dimer may identify patients at low risk of recurrence after a first VTE [3,4]. In a pilot, prospective, cohort study we aimed to assess the negative predictive value of D-dimer in patients with recurrent VTE. Patients with negative D-dimer while on treatment stopped anti coagulation and underwent repeated testing after 7, 15, and 30 days; treatment was resumed if D-dimer turned positive and permanently stopped if it remained negative. The study was interrupted after the enrolment of 75 patients. At that time, treating physicians decided treatment resumption in 12.2% of the patients, but the majority of events were distal or superficial vein thromboses. The rate of objectively documented recurrent proximal deep vein thrombosis (DVT) and/or pulmonary embolism (PE) was 2.56% (95% CI 0.13, 15.07%) in the 39 patients with persistently negative D-di

Some of the main factors associated with cerebral venous thrombosis include oral contraceptives, pregnancy, cancer, head trauma and obesity. Symptoms include severe headaches, blurred vision and nausea. Rarely, CVT can lead to brain swelling and bleeding and, when most severe, stroke and permanent brain damage.. Our study found that the number of cases of cerebral venous thrombosis in the United States is three times higher than previously reported, and who is being diagnosed with the condition is changing, said study author Fadar Oliver Otite, M.D., Sc.M., of the SUNY Upstate Medical University in Syracuse, N.Y. and a member of the American Academy of Neurology. CVT is most common in younger women and the higher incidence in this group has been attributed, in part, to the use of birth control pills and pregnancy. However, our new analysis did not find an increase in this population over time, but rather showed increases in men and older women.. For the study, researchers reviewed hospital ...

The conical shape allows central filling of emboli while allowing blood on the periphery to flow freely.With the adoption of outpatient therapy for proximal DVT, the initial management of DVT increasingly becomes the responsibility of the emergency physician.This was not significantly different than historical controls.The larger fragments exert their anticoagulant effect by interacting with antithrombin III (ATIII) to inhibit thrombin.Management of massive and submassive pulmonary embolism, iliofemoral deep vein thrombosis, and chronic thromboembolic pulmonary hypertension: a scientific statement from the American Heart Association.A systematic review by Kahn et al found that in patients with acute DVT, early walking exercise is safe and may help to reduce acute symptoms and that in patients with previous DVT, exercise training does not increase leg symptoms acutely and may help to prevent or improve the postthrombotic syndrome.Additionally, it was approved to reduce the risk of DVT and PE ...
Tweet The post-thrombotic syndrome (PTS) is an important chronic complication of deep vein thrombosis (DVT). Another condition known as chronic venous insufficiency (CVI) may develop following a PTS, which in some cases can be the cause for the onset of lymphedema, which is the reason for the discussion of this topic..

Objective: To summarize the currently published scientific evidence for the venous flow effects of mechanical devices, particularly intermittent pneumatic compression, and the relation to prevention of deep vein thrombosis (DVT). Summary Background Data: While intermittent pneumatic compression is an established method of DVT prophylaxis, the variety of systems that are available can use very different compression techniques and sequences. In order for appropriate choices to be made to provide the optimum protection for patients, the general performance of systems, and physiological effects of particular properties, must be analyzed objectively. Methods: Medline was searched from 1970 to 2002, and all relevant papers were searched for further appropriate references. Papers were selected for inclusion when they addressed specifically the questions posed in this review. Results: All the major types of intermittent compression systems are successful in emptying deep veins of the lower limb and ...

This study was undertaken to determine the accuracy of color Doppler imaging in the diagnosis of portal vein thrombosis. Two hundred fifteen patients were studied with color Doppler imaging to determine patency of the main portal vein. Sonographic findings were confirmed in 75 patients, aged 19 to 66 years. Correlation with angiography was obtained in 13 patients, and surgical correlation was obtained in the remaining 62. Nine patients had portal vein thrombosis on the basis of these gold standards. Sonograms were classified as showing either patency or thrombosis, depending on the ability to show color flow within the main portal vein. Agreement between sonography and angiography or surgery was found in 69 patients (61 patent, eight thrombosed). One patient with a patent portal vein at sonography was found to have a thrombosed vessel at surgery, whereas five patients without portal venous flow at sonography had patent vessels at angiography (one patient) or surgery (four patients). Overall ...
What is factor V Leiden? The most common genetic risk factor for venous thrombosis is factor V Leiden, present in 5 percent of the general population. Factor V is one of the normal blood clotting factors. Factor V Leiden is a changed or mutated form of factor V that is inactivated 10 times slower than the normal factor V. This causes it to persist longer in the circulation, resulting in a hypercoagulable state. In other words, the blood continues clotting, resulting in possible obstruction.. One copy of the factor V Leiden gene increases the risk for venous thrombosis 4 to 8 times, while two copies of the gene increase the risk 80-fold.. Other coexisting coagulation defects can occur with factor V Leiden, and in general, the risk for thrombosis increases in patients with more than one genetic defect.. The factor V Leiden mutation is involved in 20 to 40 percent of venous thrombosis cases and is suspected in individuals who have a medical history of venous thrombosis or in families with a high ...
Patients with a significant bleeding history and normal routine laboratory tests are labelled as having unclassified bleeding disorder (UBD). Approximately one third of patients with acute deep vein thrombosis (DVT) have no risk factor identified and are labelled idiopathic. The experiments conducted herein investigate whether the phospholipid composition of the platelet membrane is contributory to the clinical phenotype. The ability of platelets and microvesicles to support thrombin generation was investigated using a thrombin generation assay tailored to be sensitive to the phospholipid membrane. Peak thrombin generation supported by washed platelets and microvesicles was reduced in UBD patients compared with healthy controls. Peak thrombin and velocity index were increased in patients with DVT. To determine whether changes in thrombin generation could be attributed to native aminophospholipids in the platelet membrane, Phosphatidylserine (PS) and Phosphatidylethanolamine (PE) were measured by ...
TY - JOUR. T1 - Prevention of deep leg vein thrombosis. AU - Gallus, A. S.. PY - 1998/4/1. Y1 - 1998/4/1. N2 - Deep vein thrombosis remains a feared complication of injury, surgery and serious acute medical illness. Prevention is required whenever significant risk factors for thrombosis exist. Graded pressure elastic stockings and other physical methods for preventing venous stasis are suitable for patients who are at low to medium risk. Patients at high risk require standard heparin or a low molecular weight heparin. Either form of heparin will do for general surgery, but low molecular weight heparins are better in major joint replacement..

Neilson LE, Rogers LR, Sundararajan S. Evaluation and Treatment of a Patient with Recurrent Stroke in the Setting of Active Malignancy. Stroke. 2018. This article by Neilson et al. reports a case of a 75-year-old female patient presenting with multiple ischemic lesions with temporal dispersion and localization in multiple arterial territories. The patient was newly diagnosed with lung cancer, more specifically mucinous adenocarcinoma, found randomly in MRI of cervical spine, which was performed as part of differential diagnosis of transient left arm weakness and numbness. Smoking was reported as a predisposing factor for lung cancer, as well as ischemic stroke.. An evaluation of the patient was then started, in order to clarify the etiology of multiple ischemic strokes. Lipoproteins measurement, ECG, carotid duplex ultrasound, lower extremity deep venous thrombosis scan and transthoracic echocardiogram were performed. It is of interest that holter heart rhythm monitoring was not performed, ...
Quick, what is the the fifth leading cause of death in the United States? Heart problems? Liver failure? Cancer? You probably wont believe me when I tell you it is flying in airplanes. Deep Vein Thrombosis in air travelers is far more frequent than most of us know. Deep vein thrombosis (DVT) is a dangerous condition where lack of movement can cause clots to form in the veins of the legs. If the clot breaks off and travels to the heart or lungs, it is often lethal. In 2001 The Lancet published an analysis estimating that 1 million cases of DVT related to air travel occur in the US every year and that 100,000 of these cases result in death (Lancet, September 8, 2001, p. 838).. According to a study in the New England Journal of Medicine, the risk increases with distance traveled. LINK The risk can be sharply reduced on long haul flights by wearing compression stockings. However many people wear them incorrectly LINK. It seems the thigh-high stockings may be more uncomfortable than the ...
This chart describes and beautifully illustrates how a thrombus (blood clot) forms, vascular circulation and pulmonary embolism. Supporting text defines deep vein thrombosis (DVT) and covers causes, consequences and main risk factors. Symptoms, complications and treatment options of DVT and pulmonary embolism are also discussed.
This 3D medical animation depicting Deep Vein Thrombosis (DVT or Deep Venous Thrombosis) begins by showing a blood clot forming in a lower leg vein. As red blood cells flow through the vein, slower moving cells and other blood elements accumulate on the venous valves, creating a stationary blood clot, or thrombus, blocking the blood flow in the vein. When the thrombus breaks free of the valve leaflet, it is then called an embolus, and travels toward the heart and lungs. The last section of the animation shows the embolus lodging in the lung tissue to form a potentially life-threatening pulmonary embolism.
People who don't wear graduated compression stockings when they fly are more than 12 times more likely to develop Deep Vein Thrombosis (DVT) than those who do, according to a research review.

Sadly the answer is YES. As a Nuvaring Pulmonary Embolism and Deep Vein Thrombosis attorney, I have written extensively about the inherent risks associated - July 18, 2012 - Can You Die From Nuvaring Deep Vein Thrombosis?
There are a number of factors that increase a persons risk of developing a deep vein thrombosis.. If a person is found to have a DVT and there is no known medical condition or recent surgery that could have caused the DVT, it is possible that an inherited condition is the cause. This is especially true in people with a family member who has also experienced a DVT or pulmonary embolism. In these cases, testing for an inherited thrombophilia may be recommended. However, finding an inherited thrombophilia does not change the way that doctors treat the venous thromboembolism, and may not increase the chance of the blood clot coming back.. Medical conditions or medications - Some medical conditions and medications increase a persons risk of developing a blood clot:. ●Pregnancy. ●Obesity. ●Smoking. ●Heart failure. ●Previous DVT or pulmonary embolism (PE). ●Increased age. ●Cancer - Some cancers increase substances in the blood that cause blood to clot.. ●Kidney problems, such as ...

  • Important potential causes of headache are pathologic processes involving the dural venous sinuses, the primary outflow pathway of blood from the brain. (
  • Thrombosis of the venous channels in the brain is an uncommon cause of cerebral infarction relative to arterial disease, but it is an important consideration because of its potential morbidity. (
  • If either an arterial or venous thrombosis loses control and starts to travel through the bloodstream, it is called an embolus. (
  • Dye injection and catheterization is also used to diagnose the presence of arterial and venous thrombosis. (
  • In 1983, Dr. Graham Hughes described the association between antiphospholipid antibodies and arterial as well as venous thrombosis. (
  • Thrombosis can occur in blood vessels in any part of the body, and the incidence of venous thrombosis is much higher than that of arterial thrombosis. (
  • Resistance to activated protein C, for example, has been used as a surrogate for venous thrombosis in women using oral contraceptives. (
  • Cerebral venous thrombosis (CVT) is often overlooked when intracranial hypertension (ICH) is isolated, hence mimicking idiopathic intracranial hypertension (IIH). (
  • Central venous thrombosis (CVT) can present with all the classical criteria for idiopathic intracranial hypertension (IIH), including normal brain CT with normal CSF content. (
  • A thrombosis to the dural sinuses causes a back-up in venous pressure, and may impair this CSF drainage resulting in increased intracranial pressure (e.g. headache, nausea, vomiting, papilledema, and visual problems). (
  • By means of the measuring of the venous pressure still existing obstacles of the outflow of the pelvic and femoral region could be separated from the lower leg and their degree of severity, too, could be quantified. (
  • The venous capacity and the venous outflow allowed with sufficient security to delimit the values of the healthy leg from those of the postthrombotic one, whereas a localization of the height and a further quantification of the postthrombotic condition failed. (
  • Improved technology of the devices as well as the establishment of venous capacity and venous outflow in one measuring process increase the value of the venous occlusion plethysmography clearly as a non-invasive method which can be carried out by a function-assistant. (
  • Nipped in the Budd': hepatic venous outflow obstruction in evolution. (
  • Budd-Chiari syndrome is defined as a hepatic venous outflow track obstruction of various etiology, which appears at different levels. (
  • This syndrome encompasses various hepatic venous outflow blocks, one of which is membranous obstruction of the IVC. (
  • There were no further predisposing factors and mesenteric venous thrombosis was ascribed to oral contraceptives. (

  • Although many surrogate markers correlate with an outcome, few have been shown to capture the effect of a treatment (for example, oral contraceptives) on the outcome (venous thrombosis). (
  • Of course, don't be afraid if you have venous thrombosis in the lower extremities. (
  • Severe venous congestion produces a clinical appearance that can be indistinguishable from the appearance of cellulitis . (
  • This challenging clinical problem has received new attention since the discovery of certain genetic variants that increase susceptibility to venous thrombosis. (
  • What is relevant in clinical practice is the question whether the absence of D-dimers excludes the presence of a venous thrombosis. (
  • A proper clinical assessment includes a careful evaluation of the patient's signs, symptoms, and risk factors for venous thrombosis. (
  • Restless legs syndrome appears to be a common overlapping clinical syndrome in people with varicose veins and other chronic venous insufficiency . (
  • Compression has been used for many centuries in the treatment of oedema and other venous and lymphatic disorders of the lower limb. (
  • Venous thrombosis may occur with headache and cranial nerve palsies. (
  • These types of blood clots are called superficial venous thrombosis or phlebitis. (
  • [ 2 ] and as many as 50% of those with image-documented venous thrombosis lack specific symptoms. (
  • This section focuses on three common problems of the venous system: varicose veins, venous insufficiency, and venous thrombosis. (
  • [13] Less commonly, but not exceptionally, varicose veins can be due to other causes, such as post-phlebitic obstruction or incontinence, venous and arteriovenous malformations. (
  • Anticardiolipin antibodies and the risk for ischemic stroke and venous thrombosis. (
  • Several small studies have reported an elevated risk of venous thrombosis (VT) with thrombophilia and oral contraceptive (OCP) use. (
  • Multiple sclerosis and the risk of systemic venous thrombosis: A systematic review. (
  • Environmental factors that cause vascular injury (e.g., surgery), stasis (e.g., prolonged immobility), or increased coagulability (e.g., hormone use) interact with genetic susceptibility to increase the risk for thrombosis. (
  • Increased risk of venous thrombosis in OC users who are carriers of factor V Leiden mutation. (
  • The length of anticoagulant therapy depends on the site of thrombosis and on the ongoing presence of risk factors. (
  • But it can trigger bleeding and that risk outweighs its small benefit in preventing an in-flight venous thrombosis, Dr. Rosendaal says. (
  • One expert believes the risk of venous thrombosis from air travel is tiny compared with more common causes. (
  • For people at high risk for thrombosis at home, it is also essential to have an ultrasound examination of the blood vessels every year. (
  • 8] Increasing attention is being paid to preserving central access in children with chronic illness, who often require prolonged or repeated venous access and who are at high risk for venous catheter-related complications that largely derive from elective decisions during catheter insertion and continuing care. (
  • Venous thrombosis (VT) is a common disorder, according to background information in the article. (
  • Cerebral venous thrombosis (CVT) is one such disorder as it carries significant morbidity and mortality. (
  • This is primarily to rule out the more common secondary pulmonary hypertension related to various left heart conditions or pulmonary venous hypertension-PH classified under WHO group II. (
  • The dural sinuses not only act as venous channels, but also contain arachnoid granulations that allow the cerebrospinal fluid (CSF) to drain from the subarachnoid space into the systemic venous system. (
