Abstract Left subclavian artery occlusion is frequently treated by stent placement. The most commented on In-Stent Restenosis excessive thrombus that squeezes the and leads to vessel occlusion. In this paper, an automatic system provided segment left arteries aortic arches from chest MRI (Magnetic Resonance Imaging) images, then identify of based gray-levels extracted arch. Experimental results...

OBJECTIVE This study was designed to investigate the relation between plasma von Willebrand factor (VWF) or endothelin-1 (ET-1) and post-carotid artery stenting (CAS) restenosis. MATERIALS AND METHODS Plasma levels of VWF and ET-1 were measured in 61 patients (36 males, mean age 64.4 ± 6.8 years) before and after CAS. The mean follow-up time was 13.8 ± 1.7 months (range, 6-63). In-stent reste...

OBJECTIVES We sought to evaluate clinical restenosis in a large population of patients who had undergone coronary stent placement. BACKGROUND One-year success after coronary stenting is limited mainly by restenosis of and requirement for repeat revascularization of the treated lesion. We studied 6,186 patients (6,219 lesions) pooled from several recently completed coronary stent trials. Clini...

BACKGROUND Restenosis prediction from published studies is hampered by inadequate sample size and incomplete angiographic follow-up. The prediction of restenosis with the existing variables is poor. The aim of the present study was to include the clinical and angiographic variables commonly associated with angiographic restenosis and develop a prediction model for restenosis from the PRESTO dat...

PURPOSE To assess the relationship between plasma homocysteine levels and restenosis after femoropopliteal percutaneous transluminal angioplasty. METHODS Over a 10-month period, 128 consecutive, symptomatic patients (72 men; median age 70 years) having successful femoropopliteal angioplasty for atherosclerotic occlusive disease were prospectively enrolled in the study. Plasma homocysteine lev...

The purpose of the present study was to identify gene polymorphisms that confer susceptibility to recurrent restenosis after bare-metal stenting of coronary arteries, and thereby to assess the genetic risk for this condition. The study population comprised 527 unrelated Japanese individuals, including 28 subjects who developed in-stent restenosis two or more times and 499 subjects without reste...

Recent reports have shown the importance of new risk factors for cardiovascular disease. We investigated the relationship between Lp(a), fibrinolytic parameters and anticardiolipin antibodies (aCL) and the occurrence of clinical recurrence owing to restenosis after elective balloon percutaneous transluminal coronary angioplasty (PTCA) without stenting. In 167 patients, undergoing PTCA, Lp(a) pl...
