OBJECTIVE To report on the short-term and long-term results of patients who underwent a third coronary balloon angioplasty for a second restenosis and to identify the correlates of a third clinical restenosis. DESIGN A retrospective analysis of clinical, angiographic, and procedure related variables of a consecutive series of patients. PATIENTS 62 patients (mean (range) age 53 (31-72) years...

Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...

OBJECTIVES This study compared the relative risks and benefits of coronary angioplasty and coronary artery bypass graft surgery in patients > 70 years old. BACKGROUND Few objective, comparative data exist to guide the clinician in the decision to use bypass surgery or angioplasty in elderly patients. METHODS The study was a case-control, retrospective analysis of 195 consecutive patients wh...

BACKGROUND Despite their potential advantages, new coronary angioplasty devices may be associated with more frequent vascular complications than noted after standard balloon angioplasty, theoretically due to the larger sheaths and prolonged periods of anticoagulation required by some of these devices. This study sought to identify the incidence, predictors, and clinical outcome of vascular comp...

Balloon dilatation angioplasty was successfully performed in five patients (ages 18 months to 17 years) with discrete aortic coarctation. The catheter size was No. 8F or 9F. Selection of balloon diameter was based on angiographic measurements of the aorta determined proximal and distal to the coarctation site. A 10 sec inflation-deflation cycle at 6 to 8 atmospheres (90 to 120 psi) was performe...

Background. Several studies suggest that repeated percutaneous transluminal coronary angioplasty procedures at the same site are associated with a progressively increasing risk of further restenosis and that short time intervals between successive procedures are predictive of future restenoses. Methods and Results. We assessed by quantitative coronary angiography the angiographic probability of...

BACKGROUND Different endovascular techniques can be employed to achieve vessel recanalization in acute stroke. We assessed whether an endovascular strategy that included angioplasty was safe and effectively recanalized acutely occluded intracranial vessels. METHODS We retrospectively reviewed 70 patients that received intra-arterial therapy for acute stroke. Patients were divided into two gro...

The incidence of coronary artery spasm at the site of previous successful angioplasty and its importance in leading to subsequent restenosis or recurrence of symptoms are unknown. Fourteen consecutive patients with single vessel coronary artery disease who had undergone successful percutaneous transluminal angioplasty were studied. All patients were given ergometrine maleate (ergonovine maleate...

We describe the use of abciximab to prevent rethrombosis of the basilar artery after transluminal angioplasty. A 60-year-old patient with vertebral basilar insufficiency and acute occlusion of the basilar artery underwent revascularization with urokinase and angioplasty. Despite the repeated use of urokinase and angioplasty under anticoagulation with heparin, the basilar artery immediately reth...
