Angioplasty of subclavian artery stenosis proximal to the vertebral origin.
نویسندگان
چکیده
Percutaneous transluminal angioplasty was performed in nine patients with symptomatic proximal left subclavian artery stenoses. All cases were technically successful. One significant delayed complication occurred in a patient whose common carotid-to-subclavian artery bypass graft occluded several months after a successful subclavian artery angioplasty with a probable subsequent embolic occlusion of the internal carotid artery. The other patients were asymptomatic after follow-up evaluations of 4-23 months.

BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty (PTA) for significant stenosis involving the origin of the vertebral artery is now a well established treatment for selected patients when posterior cerebral arterial circulation is compromised. Arterial spasm, dissection, and restenosis may occur in some instances, with subsequent hemodynamic compromise. To prevent these potential co...

Yazının dergiye gönderilme tarihi: 10.06.2009 Yazının basıma kabul tarihi: 18.07.2009 Abstract Subclavian steal syndrome occurs when there is stenosis of the subclavian artery proximal to vertebral artery. The vertebral artery originates from the subclavian artery just before the origin of internal mammarian artery and, the most common lesion of the vertebral artery is an atheromatous plaque lo...
متن کاملTreatment of posterior circulation ischemia with extracranial percutaneous balloon angioplasty and stent placement.
BACKGROUND AND PURPOSE Vertebrobasilar territory ischemia (VBI) leads to disabling neurological symptoms and poses a risk for stroke by an embolic or flow-related mechanism. We present our clinical experience in the endovascular treatment of patients with symptomatic VBI from severe atherosclerosis or dissection of the vertebral and subclavian arteries that was unresponsive to medical therapy. ...
متن کاملCarotid angioplasty and stenting in a patient with high grade stenosis of Internal Carotid Artery associated with both vertebral arteries and contralateral carotid occlusion
Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
