OBJECTIVE We wanted to retrospectively evaluate the long-term therapeutic results of iliac arterial stent placement that was done in a single institution for 10 years. MATERIALS AND METHODS From May 1994 to April 2004, 206 patients who underwent iliac arterial stent placement (mean age; 64+/-8.8) were followed up for evaluating the long term stent patency. Combined or subsequent bypass surger...

OBJECTIVE To evaluate the long-term outcome of endovascular and open treatment for nonatherosclerotic renal artery disease (NARAD). DESIGN Retrospective review. SETTING Academic institution. PATIENTS Fifty-five patients (47 women; mean age, 40 years) with NARAD. Underlying disease included Takayasu arteritis in 31 and fibromuscular dysplasia in 24. INTERVENTIONS Open revascularization a...

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...

Achieving apical foramen patency through surgical maneuvers during the biomechanical preparation of root canals is a goal sought by several schools. The aim of this study was to evaluate the deformation of the foramen as a result of using stainless steel hand files and nickeltitanium rotary instruments for achieving patency. Forty recently extracted dental roots with single canals were calibrat...

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...
