Abstract:
Objective To discuss the predictable factors for the occurrence of intra-operative aneurysm rupture(IAR).Methods A total of 84 patients with 101 aneurysms treated by neurosurgical clipping from September 2009 to September 2014 were retrospectively analyzed.The statistic analysis was performed for the risk factors of IAR such as aneurysm location,aneurysm sac,dome/neck ratio,direction,pre-operative Hunt-Hess Scale,history of hypertension and operation time.Results Eighteen cases (21.4％) occurred LAR (18 (17.8％) of aneurysms) during the operations,2 patients (2.4％) died.Statistic analysis revealed that preoperative Hunt-Hess scale (P =0.042),history of hypertension (P =0.038),aneurysm sac (P =0.012),dome/neck ratio(P=0.027),direction (P =0.010) and operation time (P =0.002) were the predictable factors for the occurrence of IAR,while the location of aneurysm was not included (P =0.199).Conclusion The IAR may be the result of the synthesis of various factors in the occurrence of intracranial aneurysms clipping.Hypertension history,Hunt-Hess scale,direction,aneurysm sac,operation time and dome/neck ratio 1.78-2.89 are the predictable factors for the occurrence of IAR and the combination of various factors leads to the occurrence of IAR.
