Abstract:
Objective To discuss the predictable factors for the occurrence of intraoperative aneurysm rupture(IAR) of anterior circulation aneurysm treated by clipping.Methods The clinical data of 96 patients with 115 aneurysms treated by clipping were retrospectively analyzed.The univariate analysis and Logistic regression analysis was performed for the risk factors of IAR such as history of hypertension,pre-operative Hunt-Hess scale,aneurysm location,aneurysm sac,aneurysm dome/neck ratio,aneurysm direction,and operation time.Results Twenty-one patients occurred IAR [18.3 ％ (21/115) of aneurysms,21.9％ (21/96) of patients] during the operation,2 patients died and 94 patients were estimated by Rank scale:0 score was for 66 patients,2 scores was for 10 patients,3 scores was for 6 patients,4 scores was for 4 patients,5 scores was for 6 patients and 6 scores was for 2 patients at 6 months after surgery.Statistic analysis revealed that history of hypertension (P =0.037),pre-operative Hunt-Hess scale (P =0.040),aneurysm direction (P =0.009),aneurysm sac (P =0.010),operation time (P =0.001) and aneurysm dome/neck ratio (P =0.029) were the predictable factors for the occurrence of IAR,while aneurysm location was not included (P =0.198).Conclusion The history of hypertension,pre-operative Hunt-Hess scale,aneurysm direction,aneurysm sac,operation time and aneurysm dome/neck ratio 1.78-2.89 are the predictable factors for the occurrence of IAR and the combination of various factors lead to the occurrence of IAR.
