Diameter reductions in the internal carotid artery (ICA) and vertebral artery (VA) contribute to the decline in brain blood with hypotension. The decline in vertebral blood flow with hypotension was greater when carbon dioxide was low; this was not apparent in the ICA.

Probe Holder

SUMMARY:Regional cerebral blood flow (rCBF) during internal carotid artery (ICA) occlusion for endarterectomy can be measured without inconvenience using the probe holder illustrated.When mean ipsilateral hemispheric CBF exceeds 20 ml/100 gm/min, an intraluminal bypass is not necessary (63% of patients), except in patients with extensive cerebrovascular disease in whom rCBF should also exceed 20 ml/100 gm/min in all areas. ICA “stump” pressure is falsely high in about 20% of patients, and is therefore not a dependable criterion for selecting patients who need shunting.While intraoperative shunting is capable of restoring pre-occlusion CBF levels, it does not eliminate the risk of intraoperative ischemic neurological deficit of probable embolic origin.

The Difference

With the intraarterial 133Xenon injection method, regional cerebral blood flow (rCBF) was measured from 35 regions of a cerebral hemisphere. The effect of a constant infusion of serotonin (10–33 μg/min) for 2–5 min into the internal carotid artery was studied eight times in five patients. During rest, mean rCBF was 43.5 ml/100g/min as compared to 42.6 ml/100g/min during serotonin infusion. The latter value was altered to 42.8 ml/100g/min if correction for altered PaCO2 was carried out. In neither instance was the difference significant. It is concluded that circulating serotonin is unlikely to cause the cerebrovascular alterations associated with classical migraine attacks.
