Cerebral 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 ...
متن کاملBlood velocity in the middle cerebral artery and regional cerebral blood flow during carotid endarterectomy.
Blood flow velocity in the middle cerebral artery, determined by transcranial Doppler ultrasonography, was monitored during 31 carotid endarterectomies. Electroencephalogram (EEG) was also monitored, and regional cerebral blood flow (rCBF) was measured. The relation between rCBF and mean velocity was dependent on the rCBF level; the correlation was strong if rCBF was less than 20 ml/100 g/min b...

Cerebral Blood Flow Measurement as a Safeguard During Carotid Endarterectomy • Intraoperative measurement of regional cerebral blood flow (rCBF) by the Xe intracarotid injection technique was performed in 17 patients operated on for stenosis of the internal carotid artery. Mean rCBF decreased from 51 ml/100 gm x minute before endarterectomy to 30 ml/100 gm x minute when the internal carotid art...
