目的探讨脑动脉瘤术中载瘤动脉暂时阻断的时机和方式。方法１８例脑动脉瘤患者，术中采用干预性载瘤动脉暂时阻断，阻断时间１８～５５ｍｉｎ，平均２７ｍｉｎ，每间隔８～１２ｍｉｎ原位松开阻断夹１０余秒，以防血栓形成，阻断超过３０ｍｉｎ则开放载瘤动脉３～５ｍｉｎ，１０例复合性控制低血压。结果术后再出血死亡１例，出现脑梗塞１例，其余１６例恢复良好。结论干预性载瘤动脉暂时阻断能明显降低动脉瘤术中成熟破裂的发生率，大部分病人能耐受分离瘤颈，夹闭动脉瘤所需时间的阻断
Objective To explore the timing and method of temporarily blocking the parent artery during cerebral aneurysm surgery. Methods Eighteen patients with cerebral aneurysms underwent temporary blocking of the interventional arterial aneurysm during the operation. The blocking time was 18-55 minutes, with an average of 27 minutes. The blocking clip was released in situ at intervals of 8 to 12 minutes to prevent thrombosis. Blocking more than 30 minutes will open the parent artery 3 to 5 minutes, and 10 cases will control hypotension. Results One patient died of rebleeding after surgery. One patient had cerebral infarction and the other 16 patients recovered well. Conclusion Interventional parent artery temporary occlusion can significantly reduce the incidence of intraoperative aneurysm maturation. Most patients can tolerate the separation of the neck of the aneurysm.
