Permissible Arterial Occlusion Time in Aneurysm Surgery: Postoperative Hyperperfusion Caused by Temporary Clipping
1999
Neurologia medico-chirurgica
The relationship between hyperperfusion and temporary clipping was evaluated to determine the safe limit for the duration of temporary clipping in aneurysm surgery. Twenty-one patients surgically treated for a ruptured aneurysm were examined using xenon-enhanced computed tomography on postoperative days 4 to 13. Eight of the 16 patients undergoing temporary clipping had focal hyper perfusion; whereas the five patients without temporary clipping had no hyperperfusion. Mean total temporary
