Cortical blood flow during extracranial-intracranial bypass surgery.
Cortical blood flow was evaluated at the time of surgery with a thermal diffusion flow probe in 25 extracranial-intracranial bypass operations. The procedures were performed 14 times for carotid occlusion, 6 times for inaccessible carotid stenosis, on 3 occasions for middle cerebral occlusion, once for basilar occlusion and once for middle cerebral stenosis. Fifty-seven different cortical regio...
متن کاملEffects of extracranial carotid stenosis on intracranial blood flow.
BACKGROUND AND PURPOSE The hemodynamic effects of extracranial carotid stenosis on intracranial blood flow are not well characterized. We sought to determine the impact of degree of stenosis, stenosis length, and residual lumen on intracranial blood flow in patients with extracranial carotid stenosis. METHODS Carotid stenosis patients who had undergone both vessel flow rate measurements using...
متن کاملCerebral blood flow after carotid occlusion and extracranial-intracranial bypass.
Eleven patients with occlusion of one internal carotid artery showed marked reduction of regional cerebral blood flow (rCBF) through the hemisphere on the affected side with high rCBF on the opposite side. Six of the patients had no surgery, during follow-up of 2 to 5 years. rCBF increased on both sides leaving a persisting asymmetry of rCBF. Five patients had extracranial-intracranial bypass; ...
متن کاملCerebral blood flow and internal carotid artery flow during carotid surgery.
Abxtract: Cerebral Blood Flow and Internal Carotid A rtery Flow During Carotid Surgery • In a series of 17 patients operated on for stenosis of the internal carotid artery, measurement of the blood flow in the internal carotid artery by a squarewave electromagnetic flowmeter was performed simultaneously with measurement of the regional cerebral blood flow (rCBF) by the Xenon injection technique...
متن کاملCerebral blood flow during carotid endarterectomy.
Cerebral blood flow (CBF) was measured during 28 carotid endarterectomies in 25 patients, by injection of 133Xe into the exposed internal carotid artery (ICA). Twenty-three patients had episodic cerebral or retinal ischemia and five had neurologic deficits before operation. Initial CBF values were variable. Increases of PaC02 caused CBF to increase in four of six patients, to increase slightly ...
