the purpose of the work presented here was to investigate endotheliumdependent relaxations in the rabbit coronary ligation model of heart failure. we investigated endothelium-dependent relaxations at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear v...

Background The saphenous vein is still the most widely used conduit in CABG surgery despite its poor long term patency. In the 1990’s a new No-touch technique for saphenous vein graft harvesting for CABG was introduced where the vein graft is harvested with a pedicle of surrounding tissue. With the No-touch technique the vein graft does not go into spasm and the vessel wall does not have to be ...

BACKGROUND We observed several cases of rare vascular anomalies within the femoral triangle during varicose vein operations. METHODS From among 2,093 patients who underwent stripping operations of the great saphenous vein between January 2002 and June 2016, 14 cases of rare vascular anomalies were enrolled in this study. RESULTS Twelve cases of femoral artery and vein transposition (0.57%),...

we investigated contraction to noradrenaline (na) and kc1 and sensitivity of na at the level of larger vessels (thoracic aorta and vena cava; left renal artery and left renal vein; lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. the model presented here is the rabbit coronary ligation model in w...

PURPOSE Radiofrequency ablation (RFA) is a widely accepted to treat the varicose vein. However, outcome studies for occlusion rate and patterns of the saphenous vein after RFA are scarce. The purpose of our study is to report the results of RFA in patients with varicose vein. METHODS We retrospectively reviewed the clinical outcomes after RFA using ClosureFAST (Covidien) catheter. We evaluate...

Ten normal and four transplanted canine jugular vein segments and four human saphenous vein segments were studied to determine the in vitro static elastic properties of venous tissue and their modification by transplantation into the arterial system. Both the intraluminal pressure and the longitudinal force were varied, and the resulting dimensions were recorded photographically. Venous segment...

Among the first 400 patients undergoing saphenous vein coronary artery bypass at Stanford Medical Center, 67 (18%) met criteria for "preinfarction angina". Angina was alleviated and possible myocardial infarction was prevented utilizing these surgical technics. The overall operative mortality rate in the preinfarction angina patients was 10.4%, which contrasted strikingly with a 1.5% operative ...

INTRODUCTION The pattern of venous reflux in Thai patients with chronic venous insufficiency (CVI) was studied in correlation with clinical manifestations. METHODS Ultrasonography findings and clinical data were prospectively collected and retrospectively reviewed. RESULTS CVI was found in 104 legs of 79 patients (mean age 59.8 ± 12.5 years; C4: 24.1%, C5: 8.9%, C6: 67.1%). 6.7% of the legs...

OBJECTIVE We evaluated our experience with segmental radiofrequency ablation (RFA) of the small saphenous vein (SSV), a less common procedure than great saphenous vein ablation, and developed a classification system and algorithm for endovenous heat-induced thrombus (EHIT), based on modifications of our prior algorithm of EHIT following great saphenous ablation. METHODS Endovenous ablation wa...
