Analysis on Factors Involved In Intraoperative Aneurysmal Rupture

Objective:To find out precautionary measures and management of intracranial aneurysmal rupture during operation.Methods:Retrospective analysis has been made of 21 aneurysm patients hospitalized in recent years,most of them were operated with the microneurosurgical clipping technique.Five cases' aneurysms ruptured during operation,and the causes of intraoperative aneurysmal rupture were analyzed.Results:Five(23.8%)of 21 cases′ aneurysms ruptured during operation,3 cases were rescued after clipping the neck of ruptured aneurysms and recovered afterwards,and 2 others died of postoperative complication.Conclusion:Intraoperative aneurysmal rupture could occur at any stage during operation.It seems reasonable and possible to reduce or to avoid the incidence of intraoperative aneurysmal rupture by utilizing microneurosurgical technique,opening sufficiently the cerebral cisterns,exposing carefully the proximal end of aneurysm bearing artery first,distal end next and finally the neck part,and using a suitable aneurysm clip and clipping properly.
