目的研究颅内动脉瘤血管内电解可脱微弹簧圈(GDC)介入栓塞的安全性和有效性。方法 30例颅内动脉瘤患者(32处动脉瘤),25例表现为动脉瘤性蛛网膜下腔出血,5例是未破裂动脉瘤。均采用血管内介入治疗。其中行单纯GDC栓塞治疗动脉瘤28处,支架辅助GDC栓塞治疗4处。结果术后随访3~12个月,无一例发生再出血。恢复良好17例,中等7例,3例恢复不良,3例死亡。结论颅内动脉瘤血管内GDC介入栓塞可减少出血、再出血的风险。 Objective To study the safety and efficacy of intracranial aneurysm endoluminal detachable coil (GDC) interventional embolization. Methods Thirty patients with intracranial aneurysms (32 aneurysms), 25 with aneurysmal subarachnoid hemorrhage and 5 with unruptured aneurysms. Endovascular interventional therapy was used. There were 28 aneurysms treated with simple GDC embolization and 4 assisted by GDC embolization. Results The patients were followed up for 3 to 12 months and no rebleeding occurred. Seventeen patients recovered well, seven were moderate, three had poor recovery and three died. Conclusion Intra-arterial GDC embolization of intracranial aneurysms may reduce the risk of hemorrhage and rebleeding.
