Ultrasonography, Doppler, Duplex
Human Umbilical Vein Endothelial Cells
Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.
Ultrasonography, Doppler, Color
Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Arteriovenous Shunt, Surgical
Tissue and Organ Harvesting
Skin breakdown or ulceration caused by VARICOSE VEINS in which there is too much hydrostatic pressure in the superficial venous system of the leg. Venous hypertension leads to increased pressure in the capillary bed, transudation of fluid and proteins into the interstitial space, altering blood flow and supply of nutrients to the skin and subcutaneous tissues, and eventual ulceration.
Pulmonary Veno-Occlusive Disease
Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.
Vein of Galen Malformations
Homopolymer of tetrafluoroethylene. Nonflammable, tough, inert plastic tubing or sheeting; used to line vessels, insulate, protect or lubricate apparatus; also as filter, coating for surgical implants or as prosthetic material. Synonyms: Fluoroflex; Fluoroplast; Ftoroplast; Halon; Polyfene; PTFE; Tetron.
Catheterization, Central Venous
Upper Extremity Deep Vein Thrombosis
DEEP VEIN THROMBOSIS of an upper extremity vein (e.g., AXILLARY VEIN; SUBCLAVIAN VEIN; and JUGULAR VEINS). It is associated with mechanical factors (Upper Extremity Deep Vein Thrombosis, Primary) secondary to other anatomic factors (Upper Extremity Deep Vein Thrombosis, Secondary). Symptoms may include sudden onset of pain, warmth, redness, blueness, and swelling in the arm.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Blood Vessel Prosthesis
Tomography, X-Ray Computed
Highly specialized EPITHELIAL CELLS that line the HEART; BLOOD VESSELS; and lymph vessels, forming the ENDOTHELIUM. They are polygonal in shape and joined together by TIGHT JUNCTIONS. The tight junctions allow for variable permeability to specific macromolecules that are transported across the endothelial layer.
Vena Cava, Superior
Blood Flow Velocity
Chemical agents injected into blood vessels and lymphatic sinuses to shrink or cause localized THROMBOSIS; FIBROSIS, and obliteration of the vessels. This treatment is applied in a number of conditions such as VARICOSE VEINS; HEMORRHOIDS; GASTRIC VARICES; ESOPHAGEAL VARICES; PEPTIC ULCER HEMORRHAGE.
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow. (Stedman, 25th ed)
A spectrum of congenital, inherited, or acquired abnormalities in BLOOD VESSELS that can adversely affect the normal blood flow in ARTERIES or VEINS. Most are congenital defects such as abnormal communications between blood vessels (fistula), shunting of arterial blood directly into veins bypassing the CAPILLARIES (arteriovenous malformations), formation of large dilated blood blood-filled vessels (cavernous angioma), and swollen capillaries (capillary telangiectases). In rare cases, vascular malformations can result from trauma or diseases.
Procedures of applying ENDOSCOPES for disease diagnosis and treatment. Endoscopy involves passing an optical instrument through a small incision in the skin i.e., percutaneous; or through a natural orifice and along natural body pathways such as the digestive tract; and/or through an incision in the wall of a tubular structure or organ, i.e. transluminal, to examine or perform surgery on the interior parts of the body.
Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).

Blood Vessel Prosthesis Implantation
Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.
A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.
A condition characterized by a chronically swollen limb, often a leg with stasis dermatitis and ulcerations. This syndrome can appear soon after phlebitis or years later. Postphlebitic syndrome is the result of damaged or incompetent venous valves in the limbs. Distended, tortuous VARICOSE VEINS are usually present. Leg pain may occur after long period of standing.
Esophageal and Gastric Varices
Portasystemic Shunt, Surgical
Surgical venous shunt between the portal and systemic circulation to effect decompression of the portal circulation. It is performed primarily in the treatment of bleeding esophageal varices resulting from portal hypertension. Types of shunt include portacaval, splenorenal, mesocaval, splenocaval, left gastric-caval (coronary-caval), portarenal, umbilicorenal, and umbilicocaval.

Venous duplex scanning of the leg: range, variability and reproducibility. (1/2259)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)
Infrainguinal revascularisation in the era of vein-graft surveillance--do clinical factors influence long-term outcome? (2/2259)OBJECTIVES: To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN: A retrospective analysis. PATIENTS AND METHODS: Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex surveillance. Factors affecting patency, limb salvage and survival rates were examined. These factors were gender, diabetes, hypertension, aspirin, warfarin, ischaemic heart disease, run-off, graft type, early thrombectomy, level of anastomoses and indication for surgery. RESULTS: The 6-year primary, primary assisted and secondary patency rates were 23, 47, and 57%, respectively. Six-year limb salvage and patient survival were 68 and 45%, respectively. Primary patency was adversely influenced by the use of composite vein grafts. Early thrombectomy was the only factor that significantly influenced secondary patency. Limb salvage was worse in diabetic limbs, limbs with poor run-off and in grafts that required early thrombectomy. Postoperative survival was better in males, claudicants and in patients who took aspirin. CONCLUSIONS: Although co-morbid factors did not influence graft patency rates, diabetes did adversely effect limb salvage. This study, like others before it, confirms that aspirin significantly reduces long-term mortality in patients undergoing infrainguinal revascularisation. (+info)
Regulation of myocardial blood flow by oxygen consumption is maintained in the failing heart during exercise. (3/2259)The hemodynamic abnormalities and neurohumoral activation that accompany congestive heart failure (CHF) might be expected to impair the increase in coronary blood flow that occurs during exercise. This study was performed to determine the effects of CHF on myocardial oxygen consumption and coronary blood flow during exercise. Coronary blood flow was measured in chronically instrumented dogs at rest, during 2 stages of graded treadmill exercise under control conditions (n=10), and after the development of CHF produced by 3 weeks of rapid ventricular pacing (n=9). In the normal dogs, coronary blood flow increased during exercise in proportion to the increase in the heart rate x the left ventricular systolic blood pressure product (RPP). After the development of CHF, resting myocardial blood flow was 25% lower than normal (P<0.05). Myocardial blood flow increased during the first stage of exercise, but then failed to increase further during the second stage of exercise despite an additional increase in the RPP. Myocardial oxygen consumption during exercise was significantly lower in animals with CHF and paralleled coronary flow. Despite the lower values for coronary blood flow in animals with CHF, there was no evidence for myocardial ischemia. Thus, even during the second level of exercise when coronary flow failed to increase, myocardial lactate consumption continued and coronary venous pH did not fall. In addition, the failure of coronary flow to increase as the exercise level was increased from stage 1 to stage 2 was not associated with a further increase in myocardial oxygen extraction. Thus, cardiac failure was associated with decreased myocardial oxygen consumption and failure of oxygen consumption to increase with an increase in the level of exercise. This abnormality did not appear to result from inadequate oxygen availability, but more likely represented a reduction of myocardial oxygen usage with a secondary decrease in metabolic coronary vasodilation.

Prevalence of true vein graft aneurysms: implications for aneurysm pathogenesis. (4/2259)BACKGROUND: Circumstantial evidence suggests that arterial aneurysms have a different cause than atherosclerosis and may form part of a generalized dilating diathesis. The aim of this study was to compare the rates of spontaneous aneurysm formation in vein grafts performed either for popliteal aneurysms or for occlusive disease. The hypothesis was that if arterial aneurysms form a part of a systemic process, then the rates of vein graft aneurysms should be higher for patients with popliteal aneurysms than for patients with lower limb ischemia caused by atherosclerosis. METHODS: Infrainguinal vein grafting procedures performed from 1990 to 1995 were entered into a prospective audit and graft surveillance program. Aneurysmal change was defined as a focal increase in the graft diameter of 1.5 cm or greater, excluding false aneurysms and dilatations after graft angioplasty. RESULTS: During the study period, 221 grafting procedures were performed in 200 patients with occlusive disease and 24 grafting procedures were performed in 21 patients with popliteal aneurysms. Graft surveillance revealed spontaneous aneurysm formation in 10 of the 24 bypass grafts (42%) for popliteal aneurysms but in only 4 of the 221 grafting procedures (2%) that were performed for chronic lower limb ischemia. CONCLUSION: This study provides further evidence that aneurysmal disease is a systemic process, and this finding has clinical implications for the treatment of popliteal aneurysms. (+info)
Superficial femoral eversion endarterectomy combined with a vein segment as a composite artery-vein bypass graft for infrainguinal arterial reconstruction. (5/2259)OBJECTIVE: The purpose of this study was to determine the results of composite artery-vein bypass grafting for infrainguinal arterial reconstruction. METHODS: This study was designed as a retrospective case series in two tertiary referral centers. Forty-eight of 51 patients underwent the procedure of interest for the treatment of ischemic skin lesions (n = 42), rest pain (n = 3), disabling claudication (n = 1), and infected prosthesis (n = 2). The intervention used was infrainguinal composite artery-vein bypass grafting to popliteal (n = 18) and infrapopliteal (n = 30) arteries, with an occluded segment of the superficial femoral artery prepared with eversion endarterectomy and an autogenous vein conduit harvested from greater saphenous veins (n = 43), arm veins (n = 3), and lesser saphenous veins (n = 2). The main outcome measures, primary graft patency rates, foot salvage rates, and patient survival rates, were described by means of the life-table method for a mean follow-up time of 15.5 months. RESULTS: The cumulative loss during the follow-up period was 6% and 24% at 6 and 12 months, respectively. The primary graft patency rates, the foot salvage rates, and the patient survival rates for patients with popliteal grafts were 60.0% +/- 9.07%, 75.7% +/- 9.18%, and 93.5% +/- 6.03%, respectively, at 1 month; 53.7% +/- 11.85%, 68.9% +/- 12.47%, and 85. 0% +/- 9.92% at 1 year; and 46.7% +/- 18.19%, 68.9% +/- 20.54%, and 53.1% +/- 17.15% at 5 years. For infrapopliteal grafts, the corresponding estimates were 72.4% +/- 7.06%, 72.9% +/- 6.99%, and 92.7% +/- 4.79% at 1 month; 55.6% +/- 10.70%, 55.4% +/- 10.07%, and 77.9% +/- 9.02% at 1 year; and 33.6% +/- 22.36%, 55.4% +/- 30.20%, and 20.8% +/- 9.89% at 5 years. CONCLUSION: The composite artery-vein bypass graft is a useful autogenous alternative for infrainguinal arterial reconstruction when a vein of the required quality is not available or when the procedure needs to be confined to the affected limb.

Evaluation of lidocaine as an analgesic when added to hypertonic saline for sclerotherapy. (6/2259)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)
Evaluation of the microdialysis technique in the dog fat pad. (7/2259)In the present study the microdialysis technique was evaluated in an isolated autoperfused dog fat pad. Concentrations of glucose, lactate, and glycerol were measured in interstitial fluid by microdialysis and simultaneously in arterial and adipose venous plasma. Adipose tissue blood flow was measured by both 133Xe washout and timed weighing of venous blood. Metabolite concentrations in adipose venous plasma calculated from interstitial and arterial metabolite concentrations and 133Xe washout were positively correlated with measured venous concentrations (glucose: r = 0.95, lactate: r = 0.92, glycerol: r = 0.81). Calculated and measured venous plasma concentrations did not differ for either glucose or lactate, but for glycerol, calculated concentration was on average 76% of measured concentration. Metabolite exchanges (Fick's principle) calculated from interstitial metabolite concentrations were positively correlated with measured exchanges only for lactate (r = 0.69). In conclusion, metabolite concentrations in adipose venous plasma can be calculated from microdialysis measurements with greater accuracy for glucose and lactate than for glycerol. The precision, however, is too low to allow calculation of metabolite exchange when arteriovenous metabolite differences are low. (+info)
A method for collecting right coronary venous blood samples from conscious dogs. (8/2259)This report describes for the first time a technique to collect right coronary venous blood samples from conscious dogs. Catheters, prepared from Micro-Renathane tubing, were surgically implanted in right ventricular superficial veins of three anesthetized dogs. Also implanted were an arterial catheter, a right coronary flow transducer, and a right coronary artery constrictor. The coronary catheter was introduced at a venous bifurcation so that its side holes were positioned above the bifurcation; both ends of the catheter were exteriorized. Heparinized saline was continuously infused through the venous catheter by a battery-powered pump. The dogs were maintained for 10-13 days after surgery, and all catheters remained patent. Multiple right coronary venous samples were collected from each dog. These samples were analyzed for venous oxygen tension (PvO2) under baseline conditions, with right coronary pressure reduced to 50 mmHg, and during the reactive hyperemia after release of the right coronary artery constriction. PvO2 was 27.7 +/- 1.0 mmHg at baseline, 23.4 +/- 1.0 mmHg during coronary artery constriction, and 34.3 +/- 1.5 mmHg during reactive hyperemia. These data and the position of the catheter at autopsy demonstrated that coronary venous blood had been sampled. (+info)
Relative location of alpha- and beta-adrenoceptors to sites of release of sympathetic transmitter in the rabbit facial vein. |...
We studied alpha- and beta-adrenoceptor-mediated responses of rabbit facial vein rings to adrenergic stimulation to determine the location of the two types of receptors in relation to the sympathetic nerve terminals. Transmural electrical nerve stimulation (TNS) at low frequency elicited large beta-receptor-mediated relaxation responses in rings pretreated with phentolamine (6 x 10(-7)M). These responses were significantly greater than the corresponding alpha-receptor-mediated contractions in rings pretreated with propranolol (10(-6)M). Blockade of neuronal uptake with desmethylimipramine (DMI, 10(-7)M) increased significantly the neurogenic relaxation but had little effect on neurogenic contractility. DMI pretreatment caused a shift to the left (x 5.6) in the relaxant dose-response curve to exogenous l-norepinephrine (NE). The NE contractile dose-response curve was also shifted to the left after DMI pretreatment but by a significantly smaller amount (x 3.1). Neurogenic activation of ...

Are arterial and venous samples clinically equivalent for the estimation of pH, serum bicarbonate and potassium concentration...
AIMS: To assess the comparability of venous and arterial samples for pH, bicarbonate and potassium measurements in critically ill patients. METHODS: Simultaneous arterial and venous samples from 206 critically ill patients were analysed in duplicate. Coefficients of variation and 95% limits of agreement were calculated for arterial and venous samples. Bland-Altman plots were constructed to assess agreement between sampling sites. RESULTS: The median (range) of arterial pH, bicarbonate concentrations, potassium concentrations and glucose concentrations were 7.40 (7.01-7.56), 25 (9-41) mmol/l, 4.2 (3.1-6.8) mmol/l and 7.4 (3.0-13.5) mmol/l, respectively. Coefficients of variation for arterial and venous pH were both 0.1%, with bias (95% limits of agreement) of -0.01 (-0.03 to 0.01) for arterial and -0.01 (-0.02 to 0.01) for venous samples. The bias (95% limits of agreement) between arterial and venous samples was 0.03 (-0.02 to 0.08). Coefficients of variation for arterial and venous bicarbonate results

What are Facial Veins?
Facial veins can appear as spider veins, reticular veins, or varicose veins and are basically abnormally functioning blood vessels that become clogged and enlarged. To understand how this happens let`s examine how the veins work:. The heart is responsible for pumping blood to all areas of the body to supply the oxygen and nutrients that the body needs to survive. Arteries are the pathways that carry the blood to all of the parts of the body. Veins are one way valves that transport the blood back to the heart. When the walls of the vein become weak some of the blood trickles back into the vein and collects there, creating a pool of blood. As a result, the vein becomes clogged and engorged and visibly appears on the surface of the skin.. Spider veins are the most common facial veins. They often resemble the body of a spider, with a red dot in the center and tiny little red veins, called telangiectasias, coming out from all sides. These types of veins normally appear around the nose and cheeks. ...
Leg Veins, Facial Veins, Spider Veins - Keris Dermatology
Unwanted leg veins and spider veins are a very common cosmetic concern. They are caused by leaky valves in the veins and can be hereditary. Pregnancy and occupations that require being on the feet for long periods of time can exacerbate this condition. Wearing compression socks/ stockings and leg elevation can help slow the development of the condition. Sclerotherapy is very effective at improving the appearance of unwanted leg veins. This is a method that involves injecting the veins with a substance that reduces the diameter of the vessels, making them more difficult to see. Lasers can also be used to treat unwanted veins and are commonly used to treat broken blood vessels and veins on the face. We use the Sciton Profile 1064nm NdYAG laser to easily treat unwanted veins. Smaller veins can also be treated by Broad Band Light. We can discuss the right treatment during an in office consultation. ...
Chlamydia pneumoniae aggravates vein graft intimal hyperplasia in a rat model | BMC Microbiology | Full Text
Along with angioplasty, autologus vein grafts are commonly used for artery bypass grafting in patients with advanced arterial stenosis and drug-resistant angina pectoris. Although initially a successful procedure, long-term functionality is limited due to proliferation and migration of smooth muscle cells. Like in atherosclerosis, common chronic infections caused by viruses and bacteria may contribute to this process of vein graft failure. Here we investigated the possible role of Chlamydia pneumoniae (Cpn) in the pathogenesis of venous graft failure in an experimental animal model. In 2 groups (n = 10 rats/group), an epigastric vein-to-common femoral artery interposition graft was placed. Immediately thereafter, rats were infected with Cpn (5*108 IFU) or injected with control solutions. Rats were sacrificed three weeks after surgery and the grafts were harvested for morphometrical and immunohistochemical analysis. Cpn administration immediately after vein grafting resulted in a significant increase in
Graft-Extrinsic Cells Predominate in Vein Graft Arterialization | Arteriosclerosis, Thrombosis, and Vascular Biology
We have shown for the first time to our knowledge that even in the absence of atherosclerosis, the majority of vein graft neointimal and medial cells derive from precursors that are extrinsic to the vein at the time of grafting. We have also provided the first evidence that the arterializing vein graft wall develops largely from focal expansions of progenitor cells, which originate within and outside of the vein graft at the time of implantation. Finally, we have shown that endothelial remodeling of vein grafts is accomplished by the expansion of graft-intrinsic as well as graft-extrinsic cells, and that BM-derived cells participate in this process. Importantly, these novel insights into vein graft biology derive from a murine vein graft system that we have shown to model human vein grafts, with regard to their surgical anastomoses as well as the distribution, composition and extent of neointimal hyperplasia within the grafts.12. Sources of graft-extrinsic neointimal cells in our murine model ...

Thats where laser vein therapy comes in. Laser Vein Therapy is an easy way to have a smoother complexion. Learn how to fix your facial veins and redness in Reno, NV
The good news: Facial veins can be treated with advanced technology using several laser systems designed specifically to erase facial veins.* And only our physician, Dr. Roper, performs these treatments.. The Excel V Laser is an excellent treatment for facial veins , spots and redness, incorporating the 532 nm and 1064 laser wavelengths to gently pull facial redness, veins, and spots off the skin, states Dr. Roper. The Candela VBeam Laser, the Gentle Yag 1064 laser and the Iridex KTP 532, are also excellent lasers for my patients with facial veins and redness, requiring no preparation and minimal post-treatment care, states Dr. Roper. the 532 nm and 1064 nm laser emits a continuous wave light which passes through a crystal and is selectively absorbed by the deep red hue of the hemoglobin inside the vein, sealing the vein without bruising. One can safely combine these lasers in the same appointment in order to decrease the number of treatments that are needed to obtain maximal results for ...

Vein Center of Ocala | Nagender Reddy, MD, FACC | Vein Doctor
Veins carry blood back to the heart. Your legs contain a network of veins. Superficial veins (near the surface of the skin) connect to perforating veins. Perforating veins carry blood from the superficial veins to the deep veins of the thigh and calf. Healthy leg veins contain valves that open and close to assist the return of blood back to the heart. Venous reflux disease develops when the valves that keep blood flowing from the legs back to the heart become damaged or diseased. This can cause blood to pool in your legs, which can lead to a progression of symptoms.. ...

In a normal circulatory system, blood flows to and from the heart through arteries and veins. Arteries take oxygen rich blood away from the heart and veins return blood to the heart. As muscles contract, the blood is squeezed forward in the veins and when muscles relax, the valves shut to prevent blood from flowing backwards. When an abnormal circulatory problem exists, and the blood from the legs cannot efficiently return to the heart, the condition is known as venous insufficiency.. When the vein walls become weak or diseased, a faulty or weak valve can exist within the vein which prevents the valve from directing the blood flow upwards and against the pull of gravity. The reflux of blood in a negative direction is caused by a malfunctioning valve. This leads to a pooling of the blood or backward flow and can cause a variety of vein complications such as chronic vein disease, which includes varicose and spider veins, reticular veins, deep vein thrombosis (DVT) or blood clots, superficial ...
Influence of Emotional and Physical Stimuli on Pressure in the Isolated Vein Segment | Circulation Research
Generalized alterations in venous tone may shift large amounts of blood within the vascular system. Both physical and emotional stimuli are capable of affecting venous tone. The present report is a study in healthy males of the effects of certain of these factors on pressure (tone) in a peripheral vein segment isolated by means of specially designed, Plexiglas vein occluders. The emotional stimuli employed were the most effective of the group in increasing venous tone.. ...
Chemotherapy - Carti : Carti
Chemotherapy is often given through a thin needle that is placed in a vein on your hand or lower arm. Your nurse will put the needle in at the start of each treatment and remove it when treatment is over. Let your doctor or nurse know right away if you feel pain or burning while you are getting IV chemotherapy.. IV chemotherapy is often given through catheters or ports, sometimes with the help of a pump.. Catheters. A catheter is a soft, thin tube. A surgeon places one end of the catheter in a large vein, often in your chest area. The other end of the catheter stays outside your body. Most catheters stay in place until all your chemotherapy treatments are done. Catheters can also be used for drugs other than chemotherapy and to draw blood. Be sure to watch for signs of infection around your catheter. For more information on infection, see Infection.. Ports. A port is a small, round disc made of plastic or metal that is placed under your skin. A catheter connects the port to a large vein, most ...
Deep Vein Thrombosis - Vascular Vein Center at Gulfcoast Surgeons
In some instances your surgeon may recommend placement of a filter, which acts like a trap, to block clots from travelling up to your lungs (a PE). This is a minimally invasive procedure that we do under a local anesthetic. We place a catheter in a vein that we advance into the vena cava - the large vein in your abdomen that both of your leg veins drain into on their way to the heart and lungs. The filter looks a lot like an umbrella with no fabric, so normal blood can flow past, but the filter will trap large clots so your body can break them down. Many times these filters are removable and we can remove them when the concern for a PE has lessened. The decision to place and/or remove a filter depends on several factors that we will discuss with you.. ...
World Thrombosis Day | Catching Health
The average persons deep vein system carries about 80% of blood from the feet back up to the heart. Deep veins are located in the center of your leg under the muscles and fascia layers (thats the fibrous tissue that surrounds the muscles). The system is under a great deal of pressure, because each time you take a step, the muscles around the deep veins squeeze these veins and force the blood uphill, or back towards your heart, against gravity.. When a blood clot forms in one of the large veins - usually in one of the lower limbs, such as the thigh or calf - leading to either partially or completely blocked circulation, this is called a deep vein thrombosis (DVT). Symptoms may include pain, tenderness, swelling or discoloration of the affected area, and skin that is warm to the touch, although only about half of people with DVT experience any of these symptoms.. A clot in a deep vein can be dangerous because the high pressure could cause the clot to let go, or break free from the vein wall ...

FMRI is a technique using BOLD contrast to identify areas of cerebral activity. Large vessels contribution to this signal induces a delay in the measured response. It is therefore imperative to precisely colocalize brain activity and large veins. MR venography is an acquisition procedure using phase variations to reinforce cerebral vasculature on anatomical data. In this article, we present a method to register brain large veins and activation map in order to achieve an accurate interpretation of measured activity ...
The vein or veins entering the leaf from the petiole are called primary or first order veins. The veins branching from these are secondary or second order veins. These primary and secondary veins are considered major veins or lower order veins, though some authors include third order. Each subsequent branching is sequentially numbered, and these are the higher order veins, each branching being associated with a narrower vein diameter. In parallel veined leaves, the primary veins run parallel and equidistant to each other for most of the length of the leaf and then converge or fuse (anastomose) towards the apex. Usually many smaller minor veins interconnect these primary veins, but may terminate with very fine vein endings in the mesophyll. Minor veins are more typical of angiosperms, which may have as many as four higher orders. In contrast, leaves with reticulate venation there is a single (sometimes more) primary vein in the centre of the leaf, referred to as the midrib or costa ...

USO DE VARFARINA EM PEDIATRIA: CARACTERÍSTICAS CLÍNICAS E FARMACOLÓGICAS
DISCUSSION. All patients presented at least one risk factor associated with VTE. The most common risk factors were CVC, cancer and use of TPN. The use of CVC was the most frequent factor, as demonstrated in the study by Van Ommen et al., with neonates (94%).13 The frequency of VTE related with catheter observed in the systematic review by Vidal et al., which included 3,128 patients aged ,18 years, was 0.20 (95%CI 0.16-0.24).3 Andrew et al. verified that more than 50% of the VTE in children, which occurred in the upper venous network, were a result of the use of CVC,12 which calls our attention as to the location of VTEs in our study. More than half of the patients presented with thrombosis in the upper venous network. The mechanisms that can explain VTE related with CVC include lesions to the vessel wall caused by the CVC itself or by the infusion of substances like TPN and chemotherapy through the catheter, blockage of the blood flow or the material the catheter is made of.3,16 According to the ...
Vericose veins:causes,symptoms,risk factors and complications
In most cases vericose veins are not alwats a cause for alarm.. Many people have lived and died with them,and also had a healthy life..

Subcutaneous Ports - Atlanta Vascular & Vein Center
When a patient needs a subcutaneous port placed in the body it is typically done in an operating room setting under general anesthesia. Sometimes local anesthesia is used for adults and older children. During placement Dr. Tilara will make two small incisions in the skin - one in the chest to place the port and the other near the collarbone where the catheter will enter a vein in the lower part of the neck. The catheter is placed in a large vein in the neck and threaded into or near the right atrium of the heart. The other end of the catheter is tunnelled under the skin and attached to the port. The port is then placed under the skin in the chest and stitched to the underlying muscle. The site may be tender for a few days but will heal quickly and secure the port. ...

Neonatal | PEM Source
Youre seeing a 5 day old with a fever of 39. Attempts to get IV access have been unsuccessful. The child is alert and not toxic appearing, but youd like to get empiric antibiotics started within the first hour of evaluation. What are your options other than drilling with an IO or embarking on a potentially long sweaty frustrating attempt at a central line in a neonate? An ultrasound-guided peripheral line is one possibility if you have the skills. Another vascular access method to keep in mind is the umbilical venous line - the umbilical vein can stay patent up to 7-10 days of life! Soak the dry cord in saline soaked gauze to soften it, use a scalpel to cut straight across at 1-2cm from the base, look for the single large vein, insert a pre-flushed catheter with gentle pressure into the vein while pulling back on a syringe until you see a flash of blood.

BACKGROUND: AZD3043 is a positive allosteric modulator of the γ-aminobutyric acid type A receptor, with sedative and anesthetic properties. We describe a population pharmacokinetic (PK) model of arterial and venous concentrations of AZD3043 and the pharmacodynamic effects on bispectral index (BIS) in healthy volunteers.. METHODS: Arterial and venous plasma concentrations of AZD3043 and BIS were measured in 2 clinical studies in 125 healthy volunteers, where AZD3043 was given as a 1-minute bolus (1-6 mg/kg), a 30-minute infusion (1-81 mg/kg/h), or 0.8 + 10, 1 + 15, 3 + 30, and 4 + 40 (mg/kg bolus + mg/kg/h infusion for 30 minutes). Population PK/pharmacodynamic analysis was performed with NONMEM.. RESULTS: A recirculatory model, comprising a series of 5 compartments for the transit of drug between venous and arterial plasma, 2 peripheral distribution compartments, and 1 compartment for the nondistributive transit of drug from arterial to venous plasma, described the PK of AZD3043. Systemic ...
