Intra-Operative Monitoring of Brain Tissue O2 (PtiO2) During Aneurysm Surgery

摘要

Background: Regional cerebral blood flow may be compromised during aneurysm surgery. This may occur during vessel occlusion by temporary cliping or result from the malposition of an aneurysm clip. In this report we monitored intra-operatively the brain tissue oxygen concentration (PtiO2) to visualize regional ischaemic events.
