Varicose veins of the lower extremity (VVLE) are a frequently encountered vascular disorder in the general population. The general view that VVLE are a non-serious disease with primarily aesthetic impact is a common misconception, as the disease can have a significant negative impact on generic and disease-specific quality of life. Further, VVLE may be associated with potentially threatening clinical conditions, such as chronic venous ulceration, venous thromboembolism and haemorrhage from ruptured varicose veins...

BACKGROUND: Endovenous radio frequency ablation for small saphenous vein incompetence by and large appears to be superior and safer than conventional open surgery. Small saphenous vein ablation from approximately mid-calf to the point proximally where the small saphenous vein dives into the popliteal fossa is considered to be safe, as the sural nerve is in most cases separated from this segment of the small saphenous vein by the deep fascia. The outcome of the distal incompetent small saphenous vein remains unclear...

OBJECTIVE/BACKGROUND: Hemodynamic measurements of blood flow in the common femoral vein and artery can be performed readily using duplex sonography. The ratio of venous to arterial volume flow in these vessels, the venous arterial flow index (VAFI), is increased in patients with varicose veins and/or chronic venous disease. The objective was to determine the reproducibility of sonographically measured hemodynamic flow parameters using phase contrast magnetic resonance imaging (MRI). METHODS: Based on hemodynamic volume flow measurements from the common femoral vein and artery the VAFI was calculated in seven patients with varicose veins (C2, Ep, As, Pr) and 32 healthy controls using standard duplex sonography and MRI...

INTRODUCTION AND OBJECTIVES: The gold standard for the diagnosis of lower extremity deep vein thrombosis (DVT) is reported to be venous duplex ultrasound (VDU) because it is noninvasive, sensitive, relatively inexpensive, and can be performed at a patients bedside. The objective of this investigation was to measure agreement in the interpretation of VDU between multiple medical specialties. METHODS: Agreement among different physicians who typically interpret VDU images were examined...

BACKGROUND: The spectrum of chronic venous disease (CVD) is well documented in adults; clinical guidelines standardize diagnosis and treatment. There is a paucity of data published commenting on pediatric CVD exclusive of Klippel-Trénaunay syndrome (KTS) and post-thrombotic syndrome. METHODS: This study aimed to define patterns of pediatric venous disease. All venous reflux studies performed on patients <18 years of age between January 2012 and June 2014 were reviewed...

The authors analysed the results of examination and treatment of a total of 102 patients presenting with iliofemoral venous thrombosis. During treatment, ultrasonographic duplex scanning was used to determine the localization of the proximal margin of thrombotic masses, the time of appearing of the first signs of recanalization, its degree at various levels of the deep venous system, as well as alteration in velocity of the venous blood flow in the deep veins of the lower limbs. The dynamics of clinical symptoms was assessed by the visual analogue scale...

COMPARATIVE STUDY
S I Savolyuk, V S Gorbovets, V A Khodos
The results of treatment of 58 patients, suffering chronic diseases of the lower extremities veins, were analyzed. In 28 patients a vertical reflux was eliminated using endovascular laser coagulation, in 32 patients--a standard phlebectomy in accordance to Babcock method was performed. The complications rate was compared as well as the term of the patients' stationary treatment. After elimination of endovascular laser coag- ulation the complications rate and severity is significantly lesser, than after a standard phiebectomy...

OBJECTIVE: Although the end cephalic vein-to-side radial artery arteriovenous fistula is the "gold standard" procedure for primary hemodialysis access, it is associated with high rates of primary failure because of the development of neointimal hyperplasia and juxta-anastomotic stenosis. We report initial results of a new approach to perform radial-cephalic fistulas, radial artery deviation and reimplantation (RADAR), designed to avoid juxta-anastomotic stenosis. METHODS: RADAR patients' data were prospectively maintained and retrospectively reviewed and compared with a historical control group of traditional radial-cephalic fistulas created in the same center...

INTRODUCTION: Unilateral leg swelling with suspicion of deep venous thrombosis (DVT) is a common emergency department (ED) presentation. Proximal DVT (thrombus in the popliteal or femoral veins) can usually be diagnosed and treated at the initial ED encounter. When proximal DVT has been ruled out, isolated calf-vein deep venous thrombosis (IC-DVT) often remains a consideration. The current standard for the diagnosis of IC-DVT is whole-leg vascular duplex ultrasonography (WLUS), a test that is unavailable in many hospitals outside normal business hours...

OBJECTIVE/BACKGROUND: To evaluate whether the outcome of radiofrequency ablation (RFA) treatment of great saphenous vein (GSV) incompetence may be predicted using strain-gauge plethysmography (SGP) with selective occlusion of the superficial venous system. METHODS: Seventeen patients (20 limbs) underwent endovenous RFA treatment for GSV incompetence (Clinical Etiology Anatomy Pathophysiology classification C2-C5; "C-group"). Duplex ultrasound (DUS) and SGP were performed with selective occlusion of superficial veins before and after RFA...

OBJECTIVE: Chronic venous ulcer (CVU) is a potentially debilitating condition that remains the most common etiology for leg ulcers. The condition has significant associated costs and effect on patient quality of life. That truncal reflux can be worsened by iliac vein occlusive disease is well known. However, there has not been systematic investigation of venous duplex ultrasound (VDUS) criteria to correlate common femoral vein (CFV) reflux with iliac vein stenosis. We sought to correlate VDUS criteria for predicting iliac vein stenosis and to investigate venous outflow factors associated with CVU recurrence...

BACKGROUND: Sex is associated with disparate risk of venous thromboembolism (VTE) in nontrauma patients, with increased risk seen during pregnancy and in women on hormone-containing medications. Sex effects on VTE after trauma are unclear. Some studies have demonstrated no effect whereas others have instead shown a higher incidence of VTE among men. We hypothesized that male sex would increase the risk of VTE across all age groups in trauma patients undergoing standardized duplex screening...

Chronic venous insufficiency of the lower limbs is often underestimated and, in the absence of therapy, results in increasingly severe complications, including therapy-resistant tissue defects. Therefore, early diagnosis and adequate therapy is of particular importance. External counter pulsation (ECP) therapy is a method used to assist the venous system. The main principle of ECP is to squeeze the inner leg vessels by muscle contractions, which are evoked by functional electrical stimulation. A new adaptive trigger method is proposed, which improves and supplements the current therapeutic options by means of pulse synchronous electro-stimulation of the muscle pump...

Varicose veins have a high recurrence rate following surgery. Besides poor surgical technique, majority of these recurrences are attributable to neovascularization after both primary and repeat surgery. Authors have studied the effectiveness of a polytetrafluoroethylene (PTFE) patch interposition between the ligated vein stump and the overlying soft tissue at saphenofemoral junction in decreasing recurrence of varicose veins after initial surgery. Study was conducted on 50 patients of varicose veins with saphenofemoral junction incompetence...

BACKGROUND: The great saphenous vein (GSV) in patients with superficial venous insufficiency might act as a beneficial conduit for antegrade venous drainage and also as a harmful conduit for promotion of reflux and/or recirculation and subsequent skin changes. The aim of this study was to measure the antegrade and retrograde GSV volume displacements during calf compression and release maneuvers. This was used to quantify harm over benefit with a recirculation index (RCI). METHODS: Sixteen legs (nine right) from 16 patients (nine male) with primary superficial venous insufficiency were scanned standing with duplex ultrasound, at the upper thigh GSV, 10 cm below the sapheno-femoral junction...

OBJECTIVE: We used the Caprini venous thromboembolism risk assessment score to prospectively evaluate if there was a correlation between the Caprini scores and the incidence of postoperative deep vein thrombosis (DVT) in high-risk surgical patients. A second objective was to determine whether patients at extremely high risk need a more effective prophylactic regimen. METHODS: This prospective multicenter observational study involved 140 high-risk patients who underwent abdominal (48%) or cranial and/or spinal (52%) surgery...
