Venous thromboembolism swine model with reflux-induced venous hypertension
Objective: This study describes a novel swine model of venous thromboembolism (VTE) with reflux-induced venous hypertension. Methods: Six pigs underwent disruption of the tricuspid chordae tendineae to create reflux and venous hypertension in the femoral

Duplex assessment of venous reflux and chronic venous insufficiency: The significance of deep venous reflux [PDF]
This study was undertaken to examine the role of superficial and deep venous reflux, as defined by duplex-derived valve closure times (VCTs), in the pathogenesis of chronic venous insufficiency.Between January 1992 and November 1995, 320 patients and 500 legs were evaluated with clinical examinations and duplex scans for potential venous reflux.

Study of the venous reflux progression [PDF]
Patients with chronic venous disease (CVD) often ask whether elective vein surgery could be delayed without consequences. Because the natural history of CVD is not well known, this study was designed to determine its progression in such patients.One hundred and sixteen limbs in 90 patients who had at least 2 exams with duplex ultrasound (DU) scanning ...

Deep venous thrombosis and superficial venous reflux [PDF]
Although superficial venous reflux is an important determinant of post-thrombotic skin changes, the origin of this reflux is unknown. The purpose of this study was to evaluate the frequency and etiologic mechanisms of superficial venous reflux after acute deep venous thrombosis (DVT).Patients with a documented acute lower extremity DVT were asked to ...

Lower extremity venous reflux. [PDF]
Venous incompetence in the lower extremity is a common clinical problem. Basic understanding of venous anatomy, pathophysiologic mechanisms of venous reflux is essential for choosing the appropriate treatment strategy. The complex interplay of venous pressure, abdominal pressure, venous valvular function and gravitational force determine the venous ...

Purpose Spectral Doppler ultrasound (SDUS) is used for quantifying reflux in lower extremity varicose veins. The technique is angle-dependent opposed to the new angle-independent Vector Flow Imaging (VFI) method. The aim of this study was to compare peak
