Prevention and treatment of intraoperative rupture of intracranial aneurysms (a report of 89 cases)

Objective To explore the prevention and treatment of intraoperative rupture of intracranial aneurysm. Methods The clinical data of 89 patients with ruptured intracranial aneurysms undergoing microsurgery from January, 2006 to December, 2009 were ananlyzed retrospectively. The controlled hypotension, oppression with gelatin sponge, temporal occlusion of the parent artery and coagulating the mouth of aneurysmal rupture with bipole electric coagulator were performed and then the aneurysmal necks were clipped in 17 patients who had intraoperative rupture of the aneurysms of these 89 patients with intracranial aneurysms. Results Of 89 patients with intracranial aneurysms, 78 were recovered well, 6 mildly disabled, 3 severely disabled and 2 died. Of 17 patients who had intraoperative rupture of the aneurysms, 15 were recovered well, 1 was mildly disabled and 1 died. Conclusions The intraoperative rupture of the intracranial aneurysms can be decreased or prevented by the accurate preoperative location of the aneurysms, individualized surgical approach, good exposure of the aneurysms and skillful operative technique. The operator's calmness and the individual clipping method are very important to effective control of intraoperative bleeding due to the aneurysmal rupture in the patients with intracranial aneurysms.
