OBJECTIVE The aim of this experimental study was to study the arterial supply of the corpus cavernosum recti in the inner wall of the distal rectum in relation to haemorrhoidal ligation therapy. METHOD In 10 nonfixed human cadavers, the arterial vasculature of the rectum was studied using the Araldite casting method. Subsequently, the specimens were treated with methylbenzoate in order to obt...

BACKGROUND AND OBJECTIVES To assess the safety and efficacy of transcatheter closure of residual ductal flow after initial surgical ligation of the arterial duct. SUBJECTS AND METHODS Between June 2005 and December 2009, transcatheter occlusion of residual postsurgical ductus arteriosus was performed in six children. RESULTS The mean patient age was 10±5.5 years; mean post-procedural time s...

BACKGROUND The surgically created arteriovenous fistula has recently been recommended as the best available angioaccess for hemodialysis. Therefore, in this study, we carried out a clinical analysis on surgical procedures in the ligation and division of a distal vein to achieve similar effects as those of vein end-to-arterial side after side-to-side anastomosis. METHODS We retrospectively rev...

Metabolic Changes in Response to Acute Cerebral Ischemia Following Bilateral Carotid Artery Ligation in A rteriosclerotic Versus Nonarteriosclerotic Rats • Both the left and right carotid arteries of arteriosclerotic and nonarteriosclerotic male and female rats were surgically ligated to induce a state of sudden and severe cerebral ischemia. The animals promptly developed signs of cerebral impa...

OBJECTIVE Thrombospondin-1 (TSP1) is described as a positive regulator of vascular smooth muscle growth in cell culture. However, insight into the in vivo effects of TSP1 on smooth muscle cell (SMC) function is lacking. METHODS AND RESULTS We analyzed wild-type (WT) and TSP1-deficient (Tsp1-/-) mice in a carotid artery ligation model, in which neointimal lesions form without overt mechanical ...
