We describe a technique to predict preoperatively the safety of permanently occluding an internal carotid artery. The method was performed by imaging stable xenon cerebral blood flow (CBF) with the internal carotid artery both open and temporarily occluded with a nondetachable balloon on a double lumen Swan-Ganz catheter. Patients were those in whom we planned to sacrifice the internal carotid ...

Atherosclerotic and dysplastic aneurysms of the extracranial internal carotid artery are rare in Japan. We have experienced only four cases since 1982. The patients were two men and two women with a mean age of 67 years (range 51 to 82 years). All four patients had a saccular type aneurysm; sizes ranged from 30 to 75 mm. Aneurysmectomy and end-to-end anastomosis of the internal carotid artery c...

Spontaneous dissecting aneurysm of the extracranial internal carotid artery is uncommon, and simultaneous onset of multiple dissecting aneurysms is rare in patients without congenital or traumatic risk factors. A few reports suggest that extracranial internal carotid artery dissecting aneurysms can grow after SAH due to another intracranial dissecting aneurysm. The present report describes two ...

Carotid stump syndrome (CSS) is known to be one of the causes of recurrent ipsilateral ischemic stroke following the occlusion of the internal carotid artery (ICA). The present study describes a case of left CSS in a 50-year-old patient presenting with a central retinal artery embolism following internal carotid and middle cerebral artery occlusion. The central retinal artery embolism was belie...

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...
