PURPOSE To determine the clinical effectiveness of parent artery occlusion of the carotid or vertebral artery by means of temporary proximal flow arrest and microcoils. METHODS Nineteen parent artery occlusions (15 carotid, four vertebral) were performed in 19 patients who successfully passed a balloon test occlusion. In these patients, endovascular occlusion of the carotid or vertebral arter...

To enhance the consistency of the ischemic insult caused by reversible transorbital middle cerebral artery occlusion, we investigated the variability of somatosensory evoked potential amplitudes and regional cerebral blood flow in 26 anesthetized cats using four procedures to induce transient ischemia. These procedures included 60 minutes of left middle cerebral artery occlusion with or without...

BACKGROUND AND PURPOSE An animal model of selective middle cerebral artery (MCA) occlusion is needed for evaluation of intra-arterial (IA) delivery of thrombolytic agents. We describe a technique for MCA thrombo-occlusion in the rabbit with real-time angiographic documentation of occlusion and thrombolytic recanalization. METHODS After femoral artery cutdown, a microcatheter was advanced from...

INTRODUCTION Combined endovascular interventions on carotid and coronary arteries are rare. Stenting of the unprotected coronary left main stem is a high risk procedure. We presented hemodynamically unstable patient with combined carotid artery and left main stem coronary artery stenting. CASE REPORT A 78-year-old female patient was admitted to our institution for right carotid endaterectomy....

We describe a unique case of Kimura's disease in which cerebral infarction was caused by occlusion of the right internal carotid artery. A 25-year-old man with Kimura's disease was admitted to our hospital because of left hemiparesis. Computed tomography and magnetic resonance imaging of the head showed infarction in the right frontal and temporal lobes. Cerebral angiography demonstrated right ...

BACKGROUND AND PURPOSE It is now widely accepted that thrombotic coronary artery occlusion usually follows rupture of an unstable atherosclerotic plaque. The significance of such instability in arteries supplying the brain is less well appreciated. We therefore describe the clinical and pathological features of recent, symptomatic internal carotid artery occlusion to examine the pathogenetic ro...

The angiographic appearance of the proximal end of internal carotid artery occlusion is reported in 41 patients with acute stroke in the areas of the brain supplied by the carotid artery. All patients had angiography within 6 days of stroke onset, the majority within 24--48 hours. Three angiographic configurations of internal carotid occlusion were found, in descending order of frequency: a sha...

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 new method that employs a cerebral perfusion imaging agent, 99mTc-HMPAO, is described for identifying those patients who clinically pass an internal carotid artery balloon test occlusion but who then may develop a cerebral infarction after permanent occlusion. Test balloon occlusion of the internal carotid artery was performed in 17 patients, and 99mTc-HMPAO was injected intravenously while t...
