title: [Temporary clipping and cerebral blood flow in patients with cerebral aneurysms].
abstract: Regional cerebral blood flow (RCBF) was measured with cerebral aneurysms by the H2-inhalation technique during intraoperative occlusion test in 15 patients. Temporary clipping was followed by a decrease of RCBF below the critical values in most patients. Reperfusion at the removal of a clip from the internal carotid and middle cerebral artery induced a significant hyperemia (298 +/- 55 ml/100 g x min). At the same time, there was no increase in the frequency of postoperative complications due to temporary clipping. This suggests that their development is related to the duration of cerebral ischemia and the state of the blood-brain barrier.
