Percutaneous treatment of severe carotid stenosis due to Takayasu's arteritis early after carotid endarterectomy.

Takayasu's arteritis is a chronic inflammatory disease primarily involving large vessels. The diffuse, multifocal and progressive nature of the vascular lesions make surgical repair difficult. We describe successful carotid stenting of a 39-year-old female who presented with symptomatic, aggressive, long-segment carotid restenosis 6 months following left carotid endarterectomy.

Percutaneous intervention for posterior fossa ischemia. A single center experience and review of the literature.

Objectives: The purpose of our study was to evaluate the results of endovascular treatment of symptomatic vertebro-basilar insufficiency (VBI) unresponsive to medical therapy.

Methods: Cardiac patients regularly followed in our cardiology clinic with symptoms suggestive of posterior fossa ischemia diagnosed by the attending cardiologist, had diagnostic or suspicious findings of vertebral artery stenosis on ultrasound evaluation, with reversed vertebral flow on Doppler examination. These patients were referred for selective vertebral and subclavian artery angiography.

Percutaneous vertebral artery intervention: a necessary tool in every interventional cardiologist armamentarium.

Objectives: The purpose of this study was to evaluate the results of endovascular treatment of symptomatic vertebrobasilar insufficiency unresponsive to medical therapy.

Methods: Twenty-eight patients who were regularly followed up in our cardiology clinic with symptoms suggestive of posterior fossa ischemia and with diagnostic or suspicious findings on ultrasound evaluation were evaluated with selective vertebral and subclavian artery angiography. All patients (17 men, 11 women; mean age, 64 years; range, 54-87) had critical lesions (>70% stenosis) in the vertebral or subclavian arteries or both.
