Abstract

Cerebral blood flow (CBF), ¹³³Xe intraarterial injection technique, measured in 9 patients subjected to carotid surgery. During clamping CBF was reduced, and neurological complications occurred when CBF decreased to 20–30 ml/100g-min during periods of 15–35 min. In cases of total occlusion of the internal carotid and of subclavian steal, ¹³³Xe clearance gave valuable information.
