Temporary artery occlusion during cerebral aneurysm surgery

The routine practice of temporary artery occlusion with a conventional temporary clip and the preliminary results of use of a new clip-balloon device are analyzed. The data included 138 patients operated with temporary clipping (TC) by conventional clip, 103 patients operated by direct attack on an aneurysm and 10 patients operated with the clip-balloon device elaborated on the principle of a vessel calibrated occlusion by remote control. Intraoperative aneurysm rupture (IAR) did not worsen the prognosis only when preventative TC was used. Continuous parent artery occlusion within 15 min did not increase the rate of postoperative cerebral ischemia and its duration within 20 min did not worsen the outcome even if multiple TC was used. There were no cerebral ischemic complications due to the clip-balloon device application.
