BACKGROUND AND OBJECTIVE One of the possible complications of endovenous laser ablation (EVLA) is thrombus progression into the common femoral vein or popliteal vein with the potential risk of pulmonary embolism or stroke. We set out to investigate the effect of laser energy applied under standardized treatment conditions on biomarkers of platelet and endothelial activation and on the hemostati...

BACKGROUND Conventional Valsalva maneuver (CV) is a standardprocedure to exhibit reverse venous flow atsaphenofemoral junction (SFJ) by duplex ultrasonography (DUS). However some patients could not undergo CV during examination. OBJECTIVE Compare blowing party balloon assisted Valsalva (PBAV) with CV for exhibiting the reverse venous flow at SFJ incompetence. MATERIAL AND METHOD Forty patie...

BACKGROUND Neoreflux at the sapheno-femoral junction (SFJ) is an important cause of recurrent great saphenous varicose veins. This study compares four surgical methods of ligating the SFJ with the aim to reduce the rate of neoreflux. METHOD In a prospective study, 379 patients (500 SFJ ligations) were randomised to one of four surgical procedures at the SFJ (125 groins each). In group A (cont...

BACKGROUND Recurrence of varicose veins after apparently adequate surgery is common. Neovascularisation, the formation of new vascular channels between a venous surgery site and new varicosities, is thought to be an important cause of recurrence. The aim of this study was to provide histological evidence of the 'neovascularisation'process. METHOD Tissue samples from the region of the previous...

BACKGROUND Venous valves are still discussed controversially, mainly because it is still uncertain whether primarily missing or insufficient valves or the weakness of the venous walls cause varices. Furthermore, the distribution and frequencies of major superficial tributary veins (MSTVs), which should discharge the great saphenous vein (GSV) between the terminal (TV) and preterminal valve (PTV...

Our studies were carried out on 8 male and 2 female baboons Papio anubis cadavers. We examined a total of 20 hind legs. The vessels of the hind leg were filled with coloured latex. Afterwards we prepared the superficial and deep veins and accompanying arteries. We paid attention to the location, diameter and the course of the long and short saphenous veins. We found many differences between the...
