BACKGROUND AND PURPOSE The purpose of this study was to assess the incidence of de novo aneurysm formation, the incidence of subarachnoid hemorrhage (SAH), and the growth of existing untreated aneurysms in 52 patients after therapeutic carotid artery balloon occlusion for carotid aneurysms. PATIENTS AND METHODS Between January 1996 and August 2004, 52 patients were treated with carotid artery...

artery in the neck. Obviously the pressure is not always so low and will depend on the collateral circulation which may be much better to the eye than to the brain. On the contrary, one might expect to find a near-zero low diastolic retinal artery pressure in some patients with a stroke without carotid artery occlusion but with a retinal artery stenosis or thrombosis (near-zero low pressure is ...

One recognized limitation of carotid Doppler/ultrasound is its accuracy in differentiating occlusion from near-total occlusion of the internal carotid artery, which is a crucial issue in management decisions. Clinical histories were reviewed in 58 patients with apparent occlusion of an internal carotid artery diagnosed by Doppler/ultrasound who also underwent angiography. False-positive results...

Non-invasive ultrasonic imaging of the carotid bifurcation by duplex scanning and ultrasonic arteriography combined with pulsed Doppler spectrum analysis demonstrated patency of the external and internal carotid arteries distal to a common carotid occlusion in 3 patients. Common carotid occlusion is not invariably associated with thrombosis of the ipsilateral internal carotid artery. Identifica...

We report here on a rare case of carotid artery angioplasty and stenting in a patient with spontaneous recanalization after complete occlusion of the proximal internal carotid artery (ICA). The patient initially showed severe stenosis at the left proximal ICA on MR angiography (MRA). Digital subtraction angiography (DSA) performed three days after MRA showed complete occlusion of the proximal I...

Acute common carotid occlusion in rabbits causes a reduction in ocular blood volume and ciliary artery blood pressure. At all levels of intraocular pressure, cervical sympathetic stimulation reduces these changes. The ocidar blood volume reduction after acute common carotid occlusion is not linearly related to the absolute blood pressure change or to the lowest blood pressure reached in the cil...

Carotid artery occlusion is a major risk factor for ischemic stroke. Endovascular treatment of carotid artery occlusion in high-risk patients offers a therapeutic option to reduce subsequent ischemic events. The technical success and avoidance of complications of the endovascular recanalization of occluded carotid artery is contingent on proper visualization of the vessel wall. To highlight the...
