Mid-term results of endoscopic perforator vein interruption for chronic venous insufficiency: lessons learned from the North American subfascial endoscopic perforator surgery registry. The North American Study Group. (1/535)

PURPOSE: The safety, feasibility, and early efficacy of subfascial endoscopic perforator surgery (SEPS) for the treatment of chronic venous insufficiency were established in a preliminary report. The long-term clinical outcome and the late complications after SEPS are as yet undetermined. METHODS: The North American Subfascial Endoscopic Perforator Surgery registry collected information on 148 SEPS procedures that were performed in 17 centers in the United States and Canada between August 1, 1993, and February 15, 1996. The data analysis in this study focused on mid-term outcome in 146 patients. RESULTS: One hundred forty-six patients (79 men and 67 women; mean age, 56 years; range, 27 to 87 years) underwent SEPS. One hundred and one patients (69%) had active ulcers (class 6), and 21 (14%) had healed ulcers (class 5). One hundred and three patients (71%) underwent concomitant venous procedures (stripping, 70; high ligation, 17; varicosity avulsion alone, 16). There were no deaths or pulmonary embolisms. One deep venous thrombosis occurred at 2 months. The follow-up periods averaged 24 months (range, 1 to 53 months). Cumulative ulcer healing at 1 year was 88% (median time to healing, 54 days). Concomitant ablation of superficial reflux and lack of deep venous obstruction predicted ulcer healing (P <.05). Clinical score improved from 8.93 to 3.98 at the last follow-up (P <. 0001). Cumulative ulcer recurrence at 1 year was 16% and at 2 years was 28% (standard error, < 10%). Post-thrombotic limbs had a higher 2-year cumulative recurrence rate (46%) than did those limbs with primary valvular incompetence (20%; P <.05). Twenty-eight of the 122 patients (23%) who had class 5 or class 6 ulcers before surgery had an active ulcer at the last follow-up examination. CONCLUSIONS: The interruption of perforators with ablation of superficial reflux is effective in decreasing the symptoms of chronic venous insufficiency and rapidly healing ulcers. Recurrence or new ulcer development, however, is still significant, particularly in post-thrombotic limbs. The reevaluation of the indications for SEPS is warranted because operations in patients without previous deep vein thrombosis are successful but operations in those patients with deep vein thrombosis are less successful. Operations on patients with deep vein occlusion have poor outcomes.  (+info)

Bypass graft of an occluded inferior vena cava: report of a case with patency at five years. (2/535)

Venous reconstructive surgery for chronic occlusive disease has evolved slower than its arterial counterpart. Factors intrinsic to the venous system that have been implicated in discouraging experimental and clinical results include enhanced graft thrombogenicity, low velocity of blood flow, and wall collapsibility. 1,2 We present a case of a 24-year-old man with symptomatic occlusion of the inferior vena cava, treated with a prosthetic bypass graft to the supra diaphragmatic cava. The graft was patent 5 years later, and the patient remained asymptomatic.  (+info)

Endothelial activation response to oral micronised flavonoid therapy in patients with chronic venous disease--a prospective study. (3/535)

BACKGROUND: Endothelial activation is important in the pathogenesis of skin changes due to chronic venous disease (CVD). Purified micronised flavonoid fraction has been used for symptomatic treatment of CVD for a considerable period of time. The exact mode of action of these compounds remains unknown. AIM: To study the effects of micronised purified flavonoidic fraction (Daflon 500 mg, Servier, France) treatment on plasma markers of endothelial activation. MATERIALS AND METHODS: Twenty patients with chronic venous disease were treated for 60 days with DAFLON 500 mg twice daily. Duplex ultrasonography and PPG was used to assess the venous disease. Blood was collected from a foot vein immediately before starting treatment and within 1 week of stopping treatment. Plasma markers of endothelial activation were measured using commercial ELISA kits. RESULTS: Reduction in the level of ICAM-1, 32% (141 ng/ml: 73 ng/ml) and VCAM 29% (1292 ng/ml: 717 ng/ml) was seen. Reduction in plasma lactoferrin (36% decrease, 760 ng/ml: 560 ng/ml) and VW factor occurred in the C4 group only. CONCLUSIONS: Micronised purified flavonoidic fraction treatment for 60 days seems to decrease the levels of some plasma markers of endothelial activation. This could ameliorate the dermatological effects of (CVD). This could also explain some of the pharmacological actions of these compounds. Our study demonstrates the feasibility of using soluble endothelial adhesion molecules as markers for treatment.  (+info)

Movement-related variation in forces under compression stockings. (4/535)

OBJECTIVES: Compression therapy is widely used in the treatment of venous leg ulcers, but the efficacy of this treatment is variable. Assessment of variation in compression forces associated with movement may help to elucidate the mechanism of action of compression therapy. The aim of this study was to develop and apply a system to investigate forces under compression stockings during movement. METHOD: Three sensors were placed on the medial aspect of the left leg on six healthy volunteers to monitor forces under class 2 (Continental European classification) compression stockings. Data were recorded during dorsiflexion and plantar flexion of the left foot and also during short periods of walking. RESULTS: Changes in pressure were observed, associated with dorsiflexion and plantar flexion of the foot. These changes were dependent on sensor position. Changes in pressure during walking were also position-dependent and of variable duration. CONCLUSIONS: The system enables forces associated with compression therapy to be examined during movement and may thus be of value in further understanding its mechanism of action. Foot movement can be associated with clear changes in pressure under compression stockings and rapid changes in pressure may occur during walking.  (+info)

Risk factors for erysipelas of the leg (cellulitis): case-control study. (5/535)

OBJECTIVE: To assess risk factors for erysipelas of the leg (cellulitis). DESIGN: Case-control study. SETTING: 7 hospital centres in France. SUBJECTS: 167 patients admitted to hospital for erysipelas of the leg and 294 controls. RESULTS: In multivariate analysis, a disruption of the cutaneous barrier (leg ulcer, wound, fissurated toe-web intertrigo, pressure ulcer, or leg dermatosis) (odds ratio 23.8, 95% confidence interval 10.7 to 52.5), lymphoedema (71.2, 5.6 to 908), venous insufficiency (2.9, 1.0 to 8.7), leg oedema (2.5, 1.2 to 5.1) and being overweight (2.0, 1.1 to 3.7) were independently associated with erysipelas of the leg. No association was observed with diabetes, alcohol, or smoking. Population attributable risk for toe-web intertrigo was 61%. CONCLUSION: This first case-control study highlights the major role of local risk factors (mainly lymphoedema and site of entry) in erysipelas of the leg. From a public health perspective, detecting and treating toe-web intertrigo should be evaluated in the secondary prevention of erysipelas of the leg.  (+info)

Leukocyte activation in patients with venous insufficiency. (6/535)

PURPOSE: Cell activation may play an important role in the production of venous insufficiency, just as leukocytes participate in the cause of venous ulcer. If activated, monocytes observed on venous endothelium can migrate into the venous wall and produce toxic metabolites and free oxygen radicals that may participate in valve destruction and venous wall weakening. At present, it remains uncertain to what degree leukocytes are actually activated in patients. This study was designed to explore the level of activation and to examine whether patient plasma contains an activator that leads to leukocyte activation of unstimulated naive leukocytes from volunteers without venous insufficiency disease. METHODS: Twenty-one patients (4 men, 17 women), who ranged in age from 34 to 69 years (mean age, 53.2 years), with chronic venous disease were compared with 16 healthy control volunteers (4 men, 12 women), who ranged in age from 18 to 65 years (mean age, 48.4 years). All the patients underwent evaluation with Doppler ultrasound scanning and were classified with the CEAP score.1 Nearly all the patients who smoked or were hypertensive were excluded. The blood types (ABO and Rh) of the controls were matched to the study group. Isolates of patient whole blood, plasma, or leukocytes were incubated with isolates of control whole blood, plasma, or leukocytes to separate actual activation from spontaneously observed activation. The granulocyte activation was measured with nitroblue tetrazolium (NBT) reduction and quantitation of granulocyte pseudopod formation. Hydrogen peroxide production in patient plasma was measured with a recently developed electrode method. RESULTS: Leukocytes from healthy blood and patient plasma had significantly higher NBT-positive granulocyte counts than either patient blood, healthy blood, or patient blood incubated in healthy plasma. In a comparison of patient groups across the CEAP classes, the NBT-positive granulocyte counts were significantly greater in classes 4, 5, and 6 than in classes 2 and 3 (P <.001). Pseudopod formation was significantly greater in mixtures of granulocytes in healthy blood and patient plasma than in all other groups. There was no difference in the level of pseudopod formation in control leukocytes incubated with patient plasma in patients across the CEAP spectrum. The patient plasma produced significantly higher hydrogen peroxide values than did the controls. CONCLUSION: These results suggest that patient plasma may contain an activating factor for granulocytes. The finding that activated neutrophils were fewer in number in patient whole blood than in healthy blood incubated in patient plasma could suggest that activated neutrophils in patients with chronic venous insufficiency might be trapped in the peripheral circulation. It is unknown what factors in the plasma might induce activation of naive neutrophils, but such activators could possibly be important in the pathogenesis of primary venous dysfunction and the development of chronic venous insufficiency.  (+info)

Prevalence of varicose veins and chronic venous insufficiency in men and women in the general population: Edinburgh Vein Study. (7/535)

STUDY OBJECTIVE: To determine the prevalence of varicose veins and chronic venous insufficiency (CVI) in the general population. DESIGN: Cross sectional survey. SETTING: City of Edinburgh. PARTICIPANTS: Men and women aged 18-64 years selected randomly from age-sex registers of 12 general practices. MAIN RESULTS: In 1566 subjects examined, the age adjusted prevalence of trunk varices was 40% in men and 32% in women (p < or = 0.01). This sex difference was mostly a result of higher prevalence of mild trunk varices in men. More than 80% of all subjects had mild hyphenweb and reticular varices. The age adjusted prevalence of CVI was 9% in men and 7% in women (p < or = 0.05). The prevalence of all categories of varices and of CVI increased with age (p < or = 0.001). No relation was found with social class. CONCLUSIONS: Approximately one third of men and women aged 18-64 years had trunk varices. In contrast with the findings in most previous studies, mainly conducted in the 1960s and 1970s, chronic venous insufficiency and mild varicose veins were more common in men than women. No evidence of bias in the study was found to account for this sex difference. Changes in lifestyle or other factors might be contributing to an alteration in the epidemiology of venous disease.  (+info)

Prophylactic inferior vena cava filters in trauma patients at high risk: follow-up examination and risk/benefit assessment. (8/535)

PURPOSE: The efficacy of prophylactic inferior vena cava filters in selected trauma patients at high risk has come into question in relation to risk/benefit assessment. To evaluate the usefulness of prophylactic inferior vena cava filters, we reviewed our experience and overall complication rate. METHODS: From February 1991 to April 1998, the trauma registry identified 7333 admissions. One hundred eighty-seven prophylactic inferior vena cava filters were inserted. After the exclusion of 27 trauma-related deaths (none caused by thromboembolism), 160 patients were eligible for the study. The eligible patients were contacted and asked to complete a survey and return for a follow-up examination to include physical examination, Doppler scan study, vena cava duplex scanning, and fluoroscopic examination. The patients' hospital charts were reviewed in detail. The indications for prophylactic inferior vena cava filter insertion included prolonged immobilization with multiple injuries, closed head injury, pelvic fracture, spine fracture, multiple long bone fracture, and attending discretion. RESULTS: Of the 160 eligible patients, 127 were men, the mean age was 40.3 years, and the mean injury severity score was 26.1. The mean day of insertion was hospital day 6. Seventy-five patients (47%) returned for evaluation, with a mean follow-up period of 19.4 months after implantation (range, 7 to 60 months). On survey, patients had leg swelling (n = 27), lower extremity numbness (n = 14), shortness of breath (n = 9), chest pain (n = 7), and skin changes (n = 4). All the survey symptoms appeared to be attributable to patient injuries and not related to prophylactic inferior vena cava filter. Physical examination results revealed edema (n = 12) and skin changes (n = 2). Ten Doppler scan studies had results that were suggestive of venous insufficiency, nine of which had histories of deep vein thrombosis. With duplex scanning, 93% (70 of 75) of the vena cavas were visualized, and all were patent. Only 52% (39 of 75) of the prophylactic inferior vena cava filters were visualized with duplex scanning. All the prophylactic inferior vena cava filters were visualized with fluoroscopy, with no evidence of filter migration. Of the total 187 patients, 24 (12.8%) had deep vein thrombosis develop after prophylactic inferior vena cava filter insertion, including 10 of 75 (13.3%) in the follow-up group, and one patient had a nonfatal pulmonary embolism despite filter placement. Filter insertion complications occurred in 1.6% (three of 187) of patients and included one groin hematoma, one arteriovenous fistula, and one misplacement in the common iliac vein. CONCLUSION: This study's results show that prophylactic inferior vena cava filters can be placed safely with low morbidity and no attributable long-term disabilities. In this patient population with a high risk of pulmonary embolism, prophylactic inferior vena cava filters offered a 99.5% protection rate, with only one of 187 patients having a nonfatal pulmonary embolism.  (+info)

Title: Chronic Cerebrospinal Venous Insufficiency (CCSVI) and Multiple Sclerosis (MS): A Critical Review. VOLUME: 10 ISSUE: 6. Author(s):Chiara Zecca and Claudio Gobbi. Affiliation:Servizio di Neurologia e Neuroradiologia, Neurocentro della Svizzera Italiana, Ospedale Regionale di Lugano, via esserete 46, 6903 Lugano, Switzerland.. Keywords:Chronic cerebrospinal venous insufficiency, MRI, Multiple Sclerosis, Pathogenesis, CCSVI, ECD, TCCD, MRI Venography, CCSVI Theory, Doppler sonography. Abstract: Multiple sclerosis (MS) is a chronic disease of the central nervous system with not yet completely understood pathogenesis. The so called chronic cerebrospinal venous insufficiency (CCSVI) theory has recently emerged, supporting the concept of a cerebrospinal venous drainage impairment as the cause of MS. Since the first publication on this topic with a claimed 100% specificity and sensitivity of the condition for MS diagnosis, CCSVI theory has generated a scientific and mass media debate with a ...

Two very recent scientific papers have re-opened a debate on a vascular issue, chronic cerebrospinal venous insufficiency (CCSVI), that apparently was sent in a corner by other trials and some Editorial hasty conclusions. The never-ending debate is still open and, perhaps, a one-year truce helped to calm waters and sort out, as by means of a sandbox, the situation from the vascular point of view. Before discussing why these recent papers have widened the path for CCSVI, some mind refreshing is mandatory, since the opinions are spread in all directions and a concise summary may help for those that are newcomers in this issue.... ...
Chronic cerebrospinal venous insufficiency (CCSVI or CCVI) is a term developed by Italian researcher Paolo Zamboni in 2008 to describe compromised flow of blood in the veins draining the central nervous system. Zamboni hypothesized that it played a role in the cause or development of multiple sclerosis (MS). Zamboni also devised a procedure which was termed by the media as liberation procedure or liberation therapy, involving venoplasty (or stenting) of certain veins in an attempt to improve blood flow. Within the medical community, both the procedure and CCSVI have been met with skepticism. Zambonis first published research was neither blinded nor did it have a comparison group. Zamboni also did not disclose his financial ties to Esaote, the manufacturer of the ultrasound specifically used in CCSVI diagnosis. The liberation procedure has been criticized for possibly resulting in serious complications and deaths while its benefits have not been proven. The United States Food and Drug ...
Background It has been recently hypothesised that chronic cerebrospinal venous insufficiency (CCSVI) may be an important factor in the pathogenesis of multiple sclerosis (MS). The proposed treatment for CCSVI is percutaneous transluminal angioplasty, also known as the liberation procedure, which is claimed to improve the blood flow in the brain, thereby alleviating some of the symptoms of MS. Our objective was to determine the effects of percutaneous transluminal angioplasty used for the treatment of CCSVI in people with MS.. ...
The medical fraternity is divided over the theory whether chronic cerebrospinal venous insufficiency is linked with multiple sclerosis. Here s what the latest research says.
There has been a great deal of excitment, and rightly so, over the work of Dr. Zamboni and others using venous stents and balloons to open drainage routes of the brain and improve the symptoms of many multiple sclerosis patients. He attributes the cause of MS to chronic cerebrospinal venous insufficiency. The role of venous…
There appears to be no link between chronic cerebrospinal venous insufficiency and multiple sclerosis (MS), according to new research published in CMAJ (Canadian Medical Association Journal).
Chronic venous insufficiency may be complicated by ulceration of the skin of the involved extremity. The ulcers appear to be caused by the prolonged elevation of venous pressure in the leg and the resultant edema. A device is described that counterbalances exactly the elevated pressure in the veins of the leg, regardless of the position of the patient. This hydrostatic pressure stocking prevents formation of edema without interfering with the flow of blood through the tissues. The use of this device in the treatment of ulcers due to chronic venous insufficiency is also described.. ...
Chronic venous insufficiency occurs when the leg veins do not allow blood to travel back to the heart. (Arteries carry blood away from the heart, while veins carry blood to the heart). Problems with valves in the veins can cause the blood to flow both directions, not just toward the heart. These valves that are not working properly can cause blood in the legs to pool. If chronic venous insufficiency is left untreated, pain, swelling, and leg ulcers may result.. ...

Chronic venous insufficiency occurs when your leg veins dont allow blood to flow back up to your heart. Normally, the valves in your veins make sure that blood flows toward your heart. But when these valves dont work well, blood can also flow backwards. This can cause blood to collect (pool) in your legs. Chronic venous insufficiency is not a serious health threat. But it can be painful and disabling. ...
Venous insufficiency occurs when the valves in a persons veins do not work properly. This means that the veins are less able to transport blood back to the heart.. Venous insufficiency is fairly common. According to the Society for Vascular Surgery, it affects up to 40 percent of people in the United States.. It is also usually chronic. This condition causes leg and foot swelling, varicose veins, and aching legs..

Chronic venous insufficiency (CVI) results when the veins in the legs no longer pump blood back to the heart effectively. Normally, when the leg muscles contract, they squeeze the deep veins of the legs, aiding in circulation. Veins contain one-way valves that keep the blood from flowing in the opposite direction, toward the foot. These valves can wear out over time, leading to blood leaking backward and pooling in the veins of the leg. Over time, the veins weaken and stretch. Varicose veins, or superficial veins which are dilated due to faulty valves, can also cause CVI. Blood clots can lead to CVI when they block venous blood-flow or when the clot damages the valves in the veins ...
Chronic venous insufficiency (CVI) affects about five percent of all Americans. It is directly related to varicose veins, deep vein thrombosis, and leg ulcers. Men generally get CVI in their 70s, while women develop it much earlier, in their 40s. Half a million people in the U.S. have ulcers in their legs that are caused by CVI. It is also one of the most common underlying causes of varicose veins. In this series, Dr. Juan looks at the best natural remedies for treating it.
Venous leg ulcers are a common complication of chronic venous insufficiency and are challenging to treat. A multi-disciplinary approach using guidelines from the Society of Vascular Surgeons is discussed for those ulcers that are termed pure venous leg ulcers, i.e. no other co-morbidities are contributing to the lack of healing potential.
Chronic venous insufficiency occurs when your leg veins dont allow blood to flow back up to your heart. It causes swelling (edema) of the legs. It can also cause sores on the legs, especially in the area of the ankles.. ...
The primary investigation for diagnosing DVI is a Doppler ultrasound scan, allowing the assessment for the extent of venous reflux*, any sites of stenosis, and the presence of a DVT or varicose veins.. Routine blood tests may be useful to further exclude other potential aetiologies, including FBC, U&Es, and LFTs, and an ECHO if any cardiac disease is suspected. An essential component of the investigations is documentation of foot pulses and ankle brachial pressure index as this will be required to determine suitability for compression therapy.. *If there is evidence of a venous occlusion or reflux in the pelvis as characterised by poor flow wave forms in the femoral veins or varicosities over the buttocks/perineum, then an MR Venogram may be performed.. ...

Venous stasis - Is venous stasis considered reversible? Can control it but. Not cure it. As all of the others have said, chronic venous insufficiency (venous stasis) is very treatable but, true of all superficial venous insufficiency, it cant be cured. The manifestations of cvi can be greatly improved with treatment but, long term, your veins will need to be chronically managed with periodic checkups and treatment in order to maintain the best results possible.

As each New Year dawns, many of us spend the weeks or months preceding the turning of the calendar. contemplating potential New Year resolutions. I have RESOLVED to renew and further my commitment to the education of the general public and physician community regarding the wide variety of presentations of correctable superficial venous insufficiency.. It is estimated that 35-40 million adults Americans suffer from significant venous insufficiency who present with symptoms such as painful varicose veins, swollen legs, skin discoloration, restless leg syndrome, nocturnal leg cramps and frequent nighttime urination. Until the year 2000, the only treatments for venous insufficiency were compression hose or stripping. Endovenous closure, which was introduced in 2000, has significantly changed the landscape for patients with vein disease. Since introduced, endovenous closure (the minimally invasive and effective procedure of sealing the leaky veins within the legs with a small catheter) has been used ...

The diagnosis of superficial venous insufficiency should be confirmed with duplex ultrasound. Significant reflux is defined by >1.0 second of flow reversal on venous duplex. After making the diagnosis, conservative medical therapy with graded compression stockings, leg elevation, and good skin care should be recommended. Patients with symptomatic superficial venous disease who dont respond to 3 months of compression therapy are candidates for venous ablation or other invasive therapy. It is the experience of many, that a large number of patients improve with compression but cannot tolerate it for various reasons. This may be due to discomfort related to the tightness of the stocking, intolerance related to the heat from wearing socks especially in warm climates, a fabric-related skin reaction, and difficulty with stocking application.. ...
The study was carried out to compare the efficacy of subfascial endoscopic perforator surgery (SEPS) and open subfascial ligation of perforators in varicose veins.

BACKGROUND: The aim was to clarify the role of incompetent perforators (IPs) in venous leg ulcers. This short-term report focused on safety, patient satisfaction and the fate of IPs after subfascial endoscopic perforator surgery (SEPS), or saphenous surgery alone.. METHODS: Patients aged 30-78 years with an open or recently healed venous ulcer, and with an incompetent saphenous vein and IPs, were allocated randomly to saphenous surgery alone, or in combination with SEPS. A control duplex scan was performed 6-9 months after surgery, and clinical follow-up was scheduled after 1 week, 3 and 12 months. A standard questionnaire was completed at each clinical visit.. RESULTS: Seventy-five patients were enrolled; 37 had SEPS and 38 had saphenous surgery alone. SEPS prolonged the operation by a median of 15 min (P = 0.003). Duplex imaging revealed significantly more remaining IPs in the no-SEPS group (P , 0.001). Compared with the preoperative scan, significantly more legs were free from IPs in the SEPS ...
The study is being done to determine if venous angioplasty is an effective treatment for chronic cerebrospinal venous insufficiency (CCSVI). In this condition, areas of narrowing or blockages are present in the internal jugular or azygos veins (veins which drain blood from the central nervous system) and these blockages may be associated with symptoms classically attributed to MS. Therefore, angioplasty may help to improve the symptoms associated with CCSVI and multiple sclerosis (MS). In this study, the investigators will evaluate the effectiveness of angioplasty in the treatment of CCSVI by comparing two the outcomes of two groups of patients: one group with CCSVI diagnosed on a venogram and treated with angioplasty and one group with CCSVI diagnosed on a venogram but not treated. The patients enrolled in this study, and the neurologist evaluating patients after the procedure, will not know whether or not they were treated with angioplasty ...
Chronic venous insufficiency is a common medical problem, with symptoms ranging from mildly unsightly veins to recurrent skin infections and ulcers that require hospitalization. An estimated 25 percent of the U.S. adult population has some degree of varicose veins and up to 5 percent have advanced disease. The venous system of the lower extremities is composed of deep veins that lie within the muscular compartments and superficial veins that lie closer to the skin. Venous insufficiency is a disorder of the deep veins, whereas varicose veins are a disorder of the superficial veins. Although the underlying cause is not yet fully understood, genetic, hormonal, and environmental factors have been assumed to play a role. Most cases of varicose veins cause no symptoms. However, they can cause swelling, aching, tension, leg fatigue, burning, and itching, which are relieved upon lying down or elevating the legs. As the disease progresses, skin discoloration occurs. In severe cases, recurrent skin ...
Charles Bowkley III, M.D., is a neurointerventional radiologist and the 2017 Wyoming Medical Center Physician of the Year. Here, he answers common questions about pelvic venous insufficiency (PVI).. What is PVI?. Pelvic venous insufficiency (PVI) is a condition resulting from broken valves on the inside of the gonadal (ovarian) veins. The disease process was previously referred to as Pelvic Congestion Syndrome, however the term pelvic venous insufficiency identifies the root cause and is the newer terminology. Instead of gonadal venous blood flowing up and out of the pelvis, the blood follows gravity flowing in the wrong direction - causing the pelvic veins to dilate.. What are the symptoms?. As the veins dilate in response to venous blood flowing in the wrong direction the condition becomes painful. Women state that they feel a dull ache or heaviness, which worsens throughout the day, after strenuous activity, and commonly following intercourse. These symptoms tend to improve with lying down, ...
Multiple sclerosis is a disease of the brain and spinal cord. An abnormality in the vein that drains blood from the brain and spinal cord may be associated with MS; treating this problem might hold promise as a treatment for MS.
Varicose veins are highly prevalent. In western countries, an estimated 23% of adults have varicose veins, and 6% have more advanced chronic venous disease, including skin changes and healed or active venous ulcers [1]. There are several modalities to treat varicose veins. Open surgical treatment with ligation and stripping of the saphenous vein, combined with excision of large varicosities, has been the standard of care for many years. In 1999, radiofrequency ablation (RFA) of the saphenous vein was firstly introduced as a new and minimally invasive modality for the treatment of superficial venous insufficiency. This causes thermal damage while in direct contact with the vein wall. Initial studies in the 1990s mainly used the ClosurePlus (Covidien, Mansfield, MA, USA) continuous pullback catheter. This device has evolved and the newer version of the ClosureFast (Covidien) catheter has a longer heating element. This enables operators to heat the target vein segments at a reduced procedural time. ...
Introduction: Modern surgical management of chronic venous insufficiency is possible since the development of catheter-based minimally invasive techniques, including radio-frequency ablation (RFA) and the application of colour Doppler sonography. RFA technology requires the use of tumescent anaesthesia, which prolongs the operating time. Instilling tumescent anaesthesia percutaneously below the saphenous fascia is the steepest part of the learning curve. In our study, we compared operative and postoperative results of tumescentless RFA and RFA with tumescent anaesthesia, to investigate the necessity of tumescent anaesthesia. Methods: A total of 344 patients with Doppler-confirmed great saphenous vein insufficiency underwent RFA between January and December 2012. Patients were divided into two groups according to anaesthetic management. Group 1 consisted of 172 patients: tumescent anaesthesia was given before the ablation procedure, and group 2 contained 172 patients: a local hypothermia and compression
In the operative correction of tetralogy of Fallot with a severely narrowed right ventricular outflow tract, widening of the pulmonic annulus is frequently necessary to prevent a high residual pressure gradient and to reduce right ventricular pressure overload. This can be accomplished by incising the pulmonic annulus and inserting a patch graft across the valve, but this usually results in pulmonary valvular insufficiency.. Of 426 patients who underwent total correction of Fallots tetralogy between 1959 and 1970, 63 required a patch across the pulmonic annulus. The mortality rate for this group was 30.1%, compared with a total mortality among the 426 patients of 18%. The high mortality rate is influenced by the fact that the majority were corrected in the early years of the series.. Fifteen patients were restudied by cardiac catheterization and cineangiography an average of 9.1 years after total correction. Twelve patients were asymptomatic and three patients had only mild symptoms on exertion ...
Results from a recent investigiation has established that Laser crossectomy of the GSV is a more effective method of preventing secondary anterior accessory great saphenous vein reflux
Venous insufficiency is a common condition resulting from decreased blood flow from the leg veins up to the heart, with pooling of blood in the veins. Normally, one-way valves in the veins keep blood flowing toward the heart, against the force of gravity. When the valves become weak and dont close properly, they allow blood to flow backward, a condition called reflux. Veins that have lost their valve effectiveness become elongated, rope-like, bulged, and thickened.. These enlarged, swollen vessels are known as varicose veins and are a direct result of increased pressure from reflux. A common cause of varicose veins in the legs is reflux in a thigh vein called the great saphenous, which leads to pooling in the visible varicose veins as shown in the video below. ...
All patients had slight post-operative pain in the path of the treated saphenous segment, disappearing in 5-7 days. They have been clinically checked after 3 and 6 days and with duplex-scanned after 30 days, 6 months, 1 and 2 years. Elastic-compression stocking was removed after 3 days. Only 5(4%) patients had little haematomas in the surgical incision site, disappeared in 7-10 days, 2 (2%) patients had paresthesia. Duplex scanning showed one recanalization (1%), other veins were fibrotic 1 month later and 6 months later they were completely sclerosed and barely visible as a weak hyperecogenic signal (Figure 2). GSV persistent occlusion and reflux-free was documented in 122/123 (98%) at 1 year, 113/123 (92%) at 2 years follow-up. Neither thrombosis nor thermal injury were observed, paresthesia persisting in 2 (2%) at 1 year and 1 (1%) at 2 year follow-up ...

retrograde (backward) venous flow (reflux), or a combination of these. The deficient valves in the veins in CVI fail to prevent the retrograde flow of venous blood during muscle pump activity, specifically the activity of the calf musculature during walking (ambulatory). Muscle activity in the legs applies outside pressure to the veins and a functioning system of valves forces the venous blood upward and towards the heart while walking and prevents backflow. In CVI the blood is not only forced upward towards the heart during muscle activity, but also backwards causing the pressure in the veins of the lower leg to increase even more (ambulatory venous hypertension).. This pathological increase in pressure subsequently has an effect on the blood capillaries, and more fluid is filtered from the blood into the tissues. It is the lymphatic systems responsibility to compensate for the increased amount of tissue fluid by increasing its activity; this is also known as the lymphatic safety function. ...

Varicose veins may be a sign of something more severe - venous reflux disease. Venous reflux disease develops when the valves stop working properly and allow blood to flow backward (i.e., reflux) and pool in the lower leg veins. If venous reflux disease is left untreated symptoms can worsen over time and could lead to chronic venous insufficiency. Venous reflux disease may cause the following symptoms in your legs: swelling, cramping, aching, heaviness/tiredness, varicose veins, open sores and restlessness.. ...
Doctors say then about chronic venous insufficiency. For some of us it gives itself felt only swelling of legs, others - disfiguring skin, spider veins, varicose veins and even aching. This disease affects nearly half of women in Poland - already under thirty change is every fifth!Usually we are ourselves to blame themselves, because we move too little. If besides many hours at work sitting at a desk or worse, we face - the blood circulation in the veins starts to fail.Therefore, for this reason most often they suffer from saleswoman, hairdresser or secretary.There are also important extra-curricular weight, because then the muscle pump, conveying the blood from the legs to the heart, has a difficult operation. Venous insufficiency can also be genetically determined. As a rule, inherited predisposition to it is in the female line, which is passed from grandmother to mother, and later on her granddaughter.

Venous insufficiency is caused by a series of disorders in the vein including when the valves of the veins fail to function properly. This interferes with venous return and causes blood to pool in the veins. Venous insufficiency can become more chronic and lead to spider veins, varicose veins, phlebitis, blood clots, and changes in the skin. The most serious disorder is a venous leg ulcer. Chronic Venous Disorders (CVD) is a collective term used to describe a long-standing condition involving impaired venous return in varying degrees of severity ...
Varicose veins and spider veins can be an indication of venous insufficiency. Varicose veins most commonly occur in the legs due to venous weakness (chronic venous insufficiency). As a consequence, blood and water build up in particular in the lower parts of the leg and in the foot. This leads to pain and swelling, sometimes even the formation of ulcers. When the blood in the veins can no longer flow to the heart, the veins expand, enlarge and swell, which can lead to varicose veins. Aescin enhances the crosslinking of collagen in the venous blood vessels and contributes, together with stomach-friendly vitamin C, to a normal function of the veins. Quercetin, rutin and other bioflavonoids from red vine leaves have a vessel-sealing effect, thus reducing the formation of edemata.. ...
Varicose veins are a cosmetic issue for most people, but they can be a sign of a serious medical problem for others, an expert says.. Twenty to 25 percent of Americans have varicose veins, and about 6 percent have more advanced venous disease including skin changes or, occasionally, ulcerations, Dr. Peter Gloviczki, a vascular surgeon at the Mayo Clinic in Rochester, Minn., said in a clinic news release.. Evaluation of varicose veins with ultrasound is an easy and accurate way to assess the need for treatment. New, minimally invasive therapy is available today that is effective and is performed as outpatient treatment, said Gloviczki, who helped develop national guidelines for the treatment of varicose veins for the Society for Vascular Surgery and American Venous Forum.. Varicose veins typically appear in the legs, ankles and feet. People more likely to develop them include older adults, pregnant women, obese people, and those who sit or stand for long periods of time or who have a family ...
A group of researchers in Italy is proposing a revolutionary new theory about Multiple Sclerosis. Theyve offered some compelling evidence that MS is primarily a vascular disease, and that the neurologic damage seen in MS patients has its genesis in blood flow problems within the veins of those patients. Theyre calling this theory Chronic Cerebrospinal Venous Insufficiency, or CCSVI for short.. The Italian researchers, led by Dr. Paolo Zamboni, imaged the veins leading from the brain and spinal cord of several hundred MS patients, and found that virtually all of them showed evidence of a narrowing or blockage of these vital vascular pathways. Specifically, they found blockages or stenosis in the jugular and/or azygos veins of the MS patients they studied, findings not seen in healthy control subjects or in patients with other vascular or neurolgic conditions.. These researchers theorize that these blockages constrict the flow of blood leaving the central nervous system, causing a reflux of ...
Adding foods that contain flavonoids may also help a person to shrink their varicose veins.. Flavonoids improve blood circulation, which will keep the blood flowing, and make it less likely to pool in the veins. They also help to reduce blood pressure in the arteries and can relax blood vessels, all of which can reduce varicose veins..

If you have painful, unattractive varicose veins, you are not alone: More than 30 million Americans, men and women alike, are affected by the condition called venous insufficiency, which includes varicose veins, spider veins, and telangiectasias. While rarely serious to your health, varicose and spider veins can affect your psychological and physical sense of well-being-from their unsightly appearance to the feelings of pain, cramping, heaviness and fatigue that failing veins can produce. In some cases, changes in the skin, and even leg ulcers, may develop.. Venous insufficiency occurs when the veins valves become damaged and cannot transport blood back to the heart efficiently, says Misaki M.

Family history, multiple pregnancies, occupations requiring long periods of standing, obesity and age are all contributing factors.. Fighting against gravity, healthy veins rely ...
Spider Veins. Spider veins are also known as telangiectasia and occur at the earliest stages of venous insufficiency. They are formed by small skin veins that become dilated and are visible through the skins surface. They can be blue, purple or red and are frequently extensive, forming various patterns of linear, starburst, or tree-like distribution. In the legs, they may be associated with varicose veins and venous insufficiency. They can be present in all areas of the body, including the face and the back. Varicose Veins. Varicose veins are abnormal veins that become large and tortuous. As a result, varicose veins bulge out and can be seen through the skin. They appear as rope-like structures protruding out from the skin and can occur throughout the legs and ankles. Varicose veins occur due to a disease called venous reflux. Healthy veins have tiny leaflets inside of them called valves. They allow blood to flow in one direction from the ankles towards the heart. When valves do not work, ...

Chronic venous insufficiency, also known as varicose veins or varicose veins, are swollen veins caused by abnormal accumulation of blood due to the often inherited weakness in the walls and valves of the superficial veins. This causes the veins to widen and dilate, so that blood easily accumulates when a person stands for a long time.. When the vein dilates it does not fulfill its function. These are in charge of making the blood return to the heart and that implies that the flow has to go against gravity: from the foot to the heart, Andrés García León, director of the area of ​​Vascular Surgery at the Virgen de Virgen University Hospital, explains to CuidatePlus Valme (Seville) and member of the Andalusian Society of Angiology and Vascular Surgery. The veins have valves that prevent the return of that blood flow to the foot and facilitate the rise. However, if the vein is dilated, the valves do not fulfill their function and the flow is reversed, which causes the dilation to increase ...
