颅内破裂动脉瘤栓塞后再出血分析

目的分析颅内破裂动脉瘤栓塞后再出血的发生率及其可能的影响因素。方法随访285例破裂动脉瘤病人，随访时间2-72个月，平均28.1个月，通过书信，电信以及门诊的方式进行随访，内容以询问病人症状，体征为主，重点在于动脉 瘤栓塞后是否再出血。结果4例病人发生动脉瘤再次破裂出血，再出血率为1.4%，其中不全栓塞3例，大动脉瘤2例。结论颅内破裂动脉瘤应用弹簧圈栓塞后再出血发生率大大降低，再出血主要发生于不全栓塞的动脉瘤和何种较大的动脉瘤。

Recurrent hemorrhage of colled ruptured intracranial aneurysms

Objective To analyze the recurrent hemorrhage rate and its related factors after embolization for ruptured intracranial aneurysms.Methods Two hundred and eighty-five patients with coiled ruptured intracranial aneurysms were followed up for 2 to 70 months after embolization.Information about whether the patients suffered from another hemorrhage of coiled aneurysm was collected through letters,by telephone or outpatient visit.Results Recurrent hemorrhage secondary to rupture of aneurism occurred in 4 patients(1.4%),of which 3 cases were incompletely embolized and 2 had large aneurism.Conclusion The recurrent hemorrhage rate of ruptured intracranial aneurysms after embolization with coils decreased greatly.Rebleeding usually occurred in the incompletely coiled aneurysms and large aneurysms.
