Several recent reports [1-7] have discussed the potential use of percutaneous transluminal angioplasty (PTA) for treatment of stenotic lesions of the brachiocephalic vessels. We report a case of successful angioplasty in a patient with innominate artery stenosis associated with reversal of blood flow in the right vertebral artery (right subclavian steal). The risk of cerebral embolization was r...

BACKGROUND Previous studies suggest that the migration of adventitial cells into the neointima after balloon angioplasty might have an important role in vascular lesion formation. The current experiments were designed to study the migration of adventitial cells in response to mechanical injury of the rat carotid artery. METHODS AND RESULTS Adventitial cells were stained in situ with PKH26, a ...

HYPOTHESIS Bovine pericardium (BP) demonstrates improved intraoperative hemostasis and equivalent perioperative morbidity compared with Dacron when used as patch material for angioplasty following carotid endarterectomy. OBJECTIVE To prospectively compare BP and Dacron patch angioplasty after carotid endarterectomy in a randomized fashion. METHODS Ninety-five consecutive primary carotid end...

OBJECTIVES The goal of this study was to determine whether carotid angioplasty and stenting (CAS) is equivalent to carotid endarterectomy (CEA) in patients with symptomatic carotid stenosis >70% by a randomized, controlled trial in a community hospital. BACKGROUND Carotid angioplasty and stenting has been suggested to be as effective as CEA for treatment of symptomatic carotid artery stenosis...

Objective: The aim of this study was to assess the different risk factors and their impact on the final outcome of standard carotid endarterectomy with dacron patch angioplasty. Methods: From January 1998 to December 2002, 805 (488 males, 317 females) patients underwent standard carotid endarterectomy with dacron patch angioplasty at Texas Heart Institute. The mean age was 69.5 years (range 34-...

In-stent stenosis is a possible long-term complication of carotid artery stenting. A simple and safe technique of cutting balloon angioplasty is described for carotid in-stent stenosis. The stented vessel is imaged by three-dimensional (3D) rotational angiography, the acquired projection images are transferred to a workstation, and the stenotic lesion and implanted stent are reconstructed. The ...

BACKGROUND AND PURPOSE Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS) patients with carotid stenosis were randomized between endovascular treatment and endarterectomy. The rates of residual severe stenosis and restenosis and their contribution to recurrent symptoms was unclear. METHODS Endovascular patients were treated by balloon angioplasty alone (88%) or stenting (22...

BACKGROUND AND PURPOSE Acute thromboembolic stroke complicated by ipsilateral carotid occlusion may present both mechanical and inflow-related barriers to effective intracranial thrombolysis. We sought to review our experience with a novel method of mechanical thrombectomy, in such cases, using the Possis AngioJet system, a rheolytic thrombectomy device. METHODS A review of our interventional...
