We report two female patients with Takayasu's aortoarteritis, who presented with symptoms of cerebral ischemia due to critical stenosis of the sole patent cerebral artery. Both had occlusion of both vertebral arteries and one carotid artery with critical stenosis of the other carotid artery and presented with hemiparesis contralateral to the patent but stenosed cerebral artery. They also had tr...

BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty (PTA) is currently being assessed for the treatment of carotid stenosis. In comparison with carotid endarterectomy (CEA), there is evidence of an increased risk of cerebral microembolism during the procedure. We have sought evidence of any neuropsychological sequelae of carotid PTA and compared it with CEA to demonstrate the relative ...

BACKGROUND AND PURPOSE Whether cerebral protection during carotid angioplasty and stenting (CAS) is associated with a lower risk of periprocedural stroke or death remains to be established. We report on 80 patients randomized in the CAS arm of the Endarterectomy Versus Angioplasty in Patients With Symptomatic Severe Carotid Stenosis trial comparing CAS (with or without cerebral protection) with...

We evaluate the results of stenting and angioplasty on carotid bifurcation stenotic lesions using protection systems, emphasizing the indications and technical aspects. Seventy-nine patients, mean age 64.5 years were treated from February,1998 to March, 2003. All patients were included in NASCET study criteria. Forty three patients were treated without the protection systems and thirty six were...

BACKGROUND AND PURPOSE The prevention of stroke and the correct treatment of carotid artery stenosis represent today a major debate in cardiovascular medicine. Beside carotid endarterectomy, carotid angioplasty and stenting is becoming more widely performed for the treatment of severe carotid obstructive disease, and is now accepted as a less invasive technique that may provide an alternative f...

Transluminal angioplasty of the carotid artery was successfully performed without complications in two patients, one with a stenotic internal carotid artery and one with a stenotic common carotid artery. Effectiveness of the procedure was proven by amelioration of common carotid flow. The authors outline factors to be considered in selecting patients for this procedure, including the particular...

Coexistence of a ruptured intracranial aneurysm with an internal carotid arteries carotid artery occlusion, a contralateral internal carotid artery stenoses and a intracranial venous angioma is infrequent and it suppose a complicate diagnosis and therapeutic management of either disease. We report a case who underwent a first successful microsurgical clipping of the intracranial aneurysm follow...

BACKGROUND AND PURPOSE The transluminal angioplasty and stenting procedure has been recently advocated as a potential alternative to surgical endarterectomy for the treatment of severe extracranial carotid stenosis. This study assesses the incidence and significance of intracranial hemorrhage occurring after this procedure. METHODS We retrospectively reviewed 104 carotid arteries (96 internal...

Objective and Importance: Internal Carotid Artery (ICA) stenosis is a common condition with a high prevalence in the normal population and carries a high risk of stroke. Hemodynamic impairment has been proven to be a powerful and independent risk factor for stroke. Understanding the hemodynamics beyond a stenosis may play a role in selecting patients who would benefit from treatment, determinin...
