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.

✓ Regional cerebral blood flow (rCBF) studies using the intra-arterial 133xenon method were performed on 10 patients with subarachnoid hemorrhage. Both preoperative and postoperative studies showed evidence of decreased flow in the entire hemisphere studied, and, in addition, evidence of focal ischemia, focal hyperemia, focal vasoparalysis, and often global impairment of autoregulation. The degree of flow abnormalities correlated well with the clinical grading of the neurological deficit. It is suggested that analysis of the state of autoregulation might be useful in determining the time for surgical intervention and that rCBF studies are important in defining the effects of drugs used to counteract the ischemic effects of spasm.
