i I I D B c A supraaortic arteries and, particularly, to carotid bifurcations [4-17] . We previously reported an angioplasty technique involving temporary occlusion of the internal carotid artery to prevent cerebral embolization during manipulation of ulcerated plaques [18]. The present article describes a new triple coaxial catheter system (Schneider [Europe] AG, Zurich, Switzerland) (Fig. 1 )...

Carotid near-occlusion is distal ICA luminal collapse beyond a tight stenosis, where the distal lumen should not be used for calculating percentage stenosis. Near-occlusion with full ICA collapse is well-known, with a threadlike lumen. However, near-occlusion without collapse is often subtle and can be overlooked as a usual severe stenosis. More than 10 different terms have been used to describ...

Objective: To elucidate the value of early computed tomographic (CT) signs of stroke in predicting the occlusion site in the cerebral arteries. Patients: 105 consecutive patients with acute embolic stroke affecting the anterior circulation. Methods: Four early signs were evaluated on cranial CT within six hours of stroke onset: loss of the insular ribbon (LIR); attenuation of the lentiform nucl...

BACKGROUND Carotid dissection may lead to many different types of neurological deficits, both transient and permanent. CASE DESCRIPTION We present a patient with an isolated central retinal artery occlusion who was found to have an ipsilateral carotid dissection by neck computed tomographic scan, later confirmed by angiography. CONCLUSIONS This is the first reported case of carotid dissecti...

We report a rare complication following parent-artery occlusion in a patient with radiation-induced carotid pseudoaneurysms. Both the right internal carotid artery pseudoaneurysm and the recurrent external carotid artery pseudoaneurysm were treated by parent-artery occlusion with coils. Although rebleeding was not observed after the second embolization, angiography and endoscopy at the 12-month...

A technique for safe angioplasty of atherosclerotic stenosis of internal and common carotid arteries is described in which temporary balloon occlusion of the internal carotid artery is used to prevent cerebral embolization during manifestation of ulcerated plaques. Its successful use in six atherosclerotic stenosis is described. Five angioplasties of postsurgical stenoses are also reported in w...

Acute embolic occlusion of the intracranial internal carotid bifurcation is associated with a poor prognosis. Recanalization rates of this lesion with intravenous or intraarterial thrombolysis are exceedingly low. We describe the use of balloon angioplasty after failed thrombolysis to achieve immediate recanalization of acute carotid T occlusions in two patients. At 1-month follow-up, both pati...

PURPOSE The purpose of this study was to evaluate the reliability of angiography-based balloon test occlusion (BTO) criteria to decide whether to perform internal carotid artery (ICA) permanent occlusion. METHODS From March 1999 to August 2004, 60 patients underwent therapeutic ICA occlusion. Angiographic BTO was performed systematically in all patients under general anesthesia (GA). No clini...

PURPOSE To document a case of central retinal artery occlusion after chiropractic treatment. METHODS An 87-year-old man suffered a central retinal artery occlusion immediately after chiropractic neck manipulation. RESULTS A magnetic resonance angiogram showed an atherosclerotic plaque in the ipsilateral carotid artery, which probably shed emboli during cervical joint mobilization. CONCLUS...
