The purpose of this study was to evaluate the diagnostic capability of imaging modalities used for preoperative mesenteric-left portal bypass ("Rex shunt") planning. Twenty patients with extrahepatic portal vein thrombosis underwent 57 preoperative planning abdominal imaging studies. Two readers retrospectively reviewed these studies for an ability to confidently determine left portal vein (PV)...

BACKGROUND Off-pump coronary bypass surgery has become a widely used technique during recent years. However, limited data are available with regard to 1-year patency of bypass grafts implanted on the beating heart in unselected consecutive bypass surgery candidates. The aim of this study was to compare 1-year angiographic patency of bypass grafts done on the beating heart (off pump) with those ...

BACKGROUND Invasive coronary angiography is the gold standard means of imaging bypass vessels and carries a small but potentially serious risk of local vascular complications, including myocardial infarction, stroke and death. We evaluated computed tomography as a non-invasive means of assessing graft patency. METHODS Fifty patients with previous coronary artery bypass surgery who were listed...

Vascular access in hemodialysis patients is crucial. Vascular access monitoring to ensure access patency is important for patient survival, quality of life, and blood vessel care. The ultrasound dilution method for measuring access flow is a screening tool to assess access dysfunction. Park et al. [1] performed a single-center prospective study of the variation in access flow during hemodialysi...

To determine the efficacy of using stents and stent grafts for treatment of hemodialysis graft-related stenoses which have failed angioplasty. This retrospective study was composed of 51 patients with polytetrafluoroethylene hemodialysis grafts who underwent angioplasty of a graft-related stenosis but subsequently required insertion of a stent or stent graft. The study group included 40 patient...

introduction: the purpose of this in vitro study was to investigate the influence of 5.25% sodium hypochlorite (naocl) and 0.12% chlorhexidine gluconate (chx) use separately and combined as endodontic irrigants on the apical sealing ability of two endodontic sealers. materials and methods: eighty-six extracted maxillary central incisor teeth were used. the teeth were decoronated at the cej, acc...

BACKGROUND : In November 2005, a new automated distal anastomotic device (C-Port) for coronary artery bypass grafting (CABG) was cleared by the FDA for use in the United States. This study represents a prospective evaluation of our early experience using the device with graft patency assessment determined by 64 slice multidetector row computed tomography angiography (64CT). MATERIALS AND METH...

Abtract: Recently, a new proximal anastomosis device of a saphenous vein graft (SVG) to the aorta, the PAS-Port device (Cardica, Redwood City, Calif) has been introduced and yielded encouraging results in terms of neurologic complications and early patency.1,2 However, there is a concern about the midterm (at least 1 year after surgical intervention) patency rate. The aim of this study was to e...

PURPOSE To study the arteriovenous fistula patency, duration of its maintenance, and its relative complications. MATERIALS AND METHODS One hundred and thirty patients who had undergone hemodialysis during five years (1996 to 2001) were included in this study. The patency rate and complications, including paresthesia, pain induced by ischemia, venous hypertension, infection, erythema, and edem...
