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 (...

arterial sclerosis has been extensively described but reports on venous sclerosis are very sparse. phlebosclerosis refers to the thickening and hardening of the venous wall. despite its morphological similarities with arteriosclerosis and potential morbid consequences, phlebosclerosis has gained only little attention. we report a 72 year old male with paralysis and atrophy of the right leg due ...

OBJECTIVE Failure of saphenous vein grafts remains a major limitation of coronary bypass surgery. The aims of the present study were to determine whether pressure distension of human saphenous vein induces the activation of p38-MAPK and to determine its role in apoptosis. METHODS AND RESULTS Phosphorylated p38 was detected at basal levels in human saphenous vein obtained immediately after har...

Anatomic, histologic and ultrasound studies demonstrate two distinct types of longitudinal veins in the lower extremities. The great saphenous vein is deep to the saphenous fascia. Accessory saphenous veins are superficial to this layer, have thin walls with diminished muscle cells and elastic fibers. Vein characteristics may affect long-term graft patency. This study assesses the incidence of ...

OBJECTIVE Among the veins used as a graft in myocardial revascularizations and ends, great saphenous vein is the most used. Knowing the presence and location of valves has great importance when evaluating the surgical anatomy of the great saphenous vein. Despite major surgical application and many works involving great saphenous vein, the number of valves present in it from the saphenous hiatus...

abstract vascular injury presents a great challenge to the emergency resident because these injuries require urgent intervention to prevent loss of life or limb. sometimes serious vascular injury presents with only subtle or occult signs or symptoms. the patient may present weeks or months after initial injury with symptoms of vascular insufficiency, embolization, pseudoaneurysm, arteriovenous ...

OBJECTIVE More than 50% of aortocoronary saphenous vein grafts are occluded 10 years after surgery. Intimal hyperplasia is an initial, critical step in the progression toward occlusion. To date, no clinically relevant large animal models of aortocoronary saphenous vein graft intimal hyperplasia have been fully characterized. Gene therapy holds promise as a novel treatment for aortocoronary saph...

BACKGROUND Two novel approaches to implanting a central venous catheter port in non-human primates (NHPs) using peripheral insertion are presented and compared. METHODS Sixty vascular access port (VAP) implants were attempted in 52 NHPs by saphenous vein puncture (n = 20) or saphenous vein cutdown (n = 40). RESULTS Fifty eight procedures were successful. Eighteen of 20 VAPs were successfull...

To explore the cellular adaptations and responses to hypoxia in normal human saphenous vein smooth muscle cells (SMCs) and presume what roles phenotypic modulation of normal human saphenous vein SMCs would play in varicose vein of lower extremity, we used cobalt chloride (CoCl2), a hypoxia mimetic, to treat normal human saphenous vein SMCs in vitro. The proliferating ability of cells exposed to...

OBJECTIVE The saphenous vein is the most commonly used graft in coronary artery bypass surgery, since no suitable arterial graft is available. However, the frequency of late graft failure is a cause for research into graft protection. The objective of this study was to investigate the effect of synthetic adhesive cyanoacrylate administration on the saphenous vein graft for preventing vascular d...
