OBJECTIVE An increase in transmural pressure reportedly depolarizes myocytes in various arterial blood vessels. We have examined the relationship between transmural pressure and membrane potential (E(m)) in human saphenous veins with a view to determine whether contractile force generation, hence spasmogenesis in vein grafts, involves a similar process of mechanoelectrical excitation. METHODS...
The Society for Vascular Surgery (SVS) and the American Venous Forum (AVF) have developed clinical practice guidelines for the care of patients with varicose veins of the lower limbs and pelvis. The document also includes recommendations on the management of superficial and perforating vein incompetence in patients with associated, more advanced chronic venous diseases (CVDs), including edema, ...
We studied isolated canine arteries and veins to compare the pharmacological properties of their postjunctional alpha-adrenoceptors. Rings of femoral and splenic arteries and of femoral and saphenous veins were mounted for isometric tension recording in organ chambers filled with Krebs-Ringer bicarbonate solution. The four blood vessels contracted when exposed to methoxamine, norepinephrine, ph...
This study was done to identify the normal and variants of saphenous tributaries in Korean adults. The pattern of confluence of saphenous tributaries, medial accessory saphenous, lateral accessory saphenous, superficial epigastric, superficial circumflex iliac and superficial external pudendal veins, was carefully examined in 249 lower limbs (right, 129; left, 120) of embalmed Korean cadavers (...
Primary chronic venous disorders, which according to the CEAP classification are those not associated with an identifiable mechanism of venous dysfunction, are among the most common in Western populations. Varicose veins without skin changes are present in about 20% of the population while active ulcers may be present in as many as 0.5%. Primary venous disorders are thought to arise from intrin...
INTRODUCTION Venous catheterisation in paediatric patients can be technically challenging. We examined factors affecting catheterisation of invisible and impalpable peripheral veins in children and evaluated the best site for ultrasound-guided catheterisation. METHODS Systolic pressure, age, sex, and American Society of Anaesthesiologists (ASA) physical status were determined in 96 children w...
BACKGROUNDS The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a c...

Aims: We aimed to evaluate success rate and complications after radiofrequency ablation of small Saphenous Vein and simultaneously sclerotherapy of its branches in Rasht. Materials and Methods: in this cross-sectional study we followed up the patients with success rate, possible complications including pain, hematoma, thigh and leg paresthesia, neuropathy, Endothermal Heat Induced Thrombosis (...
