破裂性颅内动脉瘤介入术中再破裂的危险因素分析及应急处理

摘要

Objective To study the risk factors of intraprocedural re-rupture (IPR) of ruptured intracranial aneurysms, and the emergency management on this event and its efficacy. Methods The clinical data of 236 patients with ruptured intracranial aneurysms, admitted to our hospital from 2005 to 2009 and treated with embolization, were retrospectively analyzed; non-conditional logistic regression analysis was performed to analyze the risk factors of IPR of ruptured intracranial aneurysms. And the emergency management of IPR and its efficacy were concluded in 16 patients with IPR. Results The risk factors of IPR of ruptured intracranial aneurysms included small aneurysms with a diameter smaller than or equaling to 3.0 mm (OR=6.353, 95% CI: 1.266-31.894, P=0.025), aneurysms at distal part of Al and M1 segment of the anterior cerebral artery or middle cerebral artery (OR=35.449, 95% CI:3.053-411.642, P=0.004), atherosclerosis (OR=5.961, 95% CI: 1.215-29.260, P=0.028), mild vasospasm (OR=13.048, 95% CI: 1.220-139.574, P=0.034) and severe vasospasm (OR=14.826, 95% CI:1.871-117.488, P=0.011). Immediate reversal of heparin anticoagulation with protamine sulfate and rapid completion of coiling were performed in 16 patients (6.78%) occurred IPR. Emergent external ventricular drainage was performed in 12 patients having above Hunt-Hess grade Ⅲ:6 patients died; 1 was under persistent vegetative state and 9 fully recovered. Conclusion Small aneurysms, atherosclerosis,cerebral vasospasm and aneurysms at the distal part of Al or M1 segment may easily lead to IPR of ruptured intracranial aneurysms. Rapid completion of coiling combined with immediate reversal of heparin anticoagulation, and emergent external ventricular drainage performed in severe patients are confirmed to be the keys, which can decrease the death rate and improve the prognosis.%目的 探讨破裂性颅内动脉瘤介入术中再破裂的危险因素、应急处理办法及疗效.方法分析自2005年至2009年广东医学院附属医院神经外科收治的236例行介入治疗的破裂性颅内动脉瘤患者的临床资料,应用非条件logistic逐步回归方法分析其介入术中再破裂的危险因素,并总结其中发生再破裂的16例患者(6.78%)的处理措施及疗效. 结果 破裂性颅内动脉瘤介入术中再破裂的危险因素为:微小动脉瘤(OR=6.353,95%CI:1.26～31.894,P=0.025),A1、M1远端动脉瘤(OR=35.449,95%CI:3.053～411.642,P=0.004),动脉粥样硬化(OR=5.961,95%CI:1.215～29.260,P=0.028),轻度脑血管痉挛(OR=13.048,95%CI:1.220～139.574,P=0.034),重度脑血管痉挛(OR=14.826,95%CI:1.871～117.488,P=0.011).16例患者均采用鱼精蛋白快速中和肝素及迅速完成动脉瘤的栓塞,其中12例Hunt-HessⅢ级以上者予急诊行脑室外引流术,结果6例死亡,1例植物生存状态,9例恢复良好. 结论 动脉硬化,脑血管痉挛,微小动脉瘤,A1、M1远端动脉瘤等因素容易导致破裂性颅内动脉瘤介入术中再破裂.快速中和肝素及迅速完成动脉瘤的栓塞,对重症患者行急诊脑室外引流术是应对介入术中动脉瘤再破裂的关键,有利于病死率降低,预后改善.
