目的：评价可脱性弹簧（ＧＤＣ）栓塞颅内动脉瘤的临床效果。材料和方法：对３２例临床表现为急性蛛网膜下腔出血、颅内占位、颅神经压迫、癫痫，并经影像学证实的颅内动脉瘤患者，经血管途径用ＧＤＣ栓塞动脉瘤腔，分别在栓塞后当时，１周，３个月，６个月，１２个月后随访血管造影，观察栓塞效果和临床情况。结果：３２只动脉瘤中，获完全栓塞１８例（５６％）．部分栓塞１２例（３８％）．２例手术失败（４％）。手术并发症７例，其中４例脑内动脉血栓，１例动脉瘤破裂，２例术后５天死亡。２例部分栓塞患者术后６个月随访血管造影示残留腔扩大行第二次栓塞。存在临床症状的所有患者经治疗后临床症状改善。结论：ＧＤＣ可控性好，可靠性、安全性强，是目前经血管治疗颅内动脉瘤的较为成熟的材料。
Objective: To evaluate the clinical effect of detachable spring (GDC) embolization intracranial aneurysm. MATERIALS AND METHODS: Thirty-two patients with acute intraamental subarachnoid hemorrhage, intracranial space occupying, cranial nerve compression, epilepsy and imaging confirmed intracranial aneurysm were enrolled in this study. Thirty-two patients with aneurism, At the time of embolization, 1 week, 3 months, 6 months, 12 months after angiography were followed up to observe the embolization effect and clinical situation. Results: In 32 aneurysms, 18 cases were completely embolized (56%). Partial embolism in 12 cases (38%). Two patients failed surgery (4%). There were 7 cases of surgical complications, including 4 cases of intracerebral arterial thrombosis, 1 case of aneurysm rupture, and 2 cases died 5 days after operation. Two patients with partial embolism after 6 months of follow-up angiography showed residual cavity expansion of the second embolization. All patients with clinical signs of clinical symptoms improved after treatment. Conclusion: GDC has good controllability, reliability and safety. It is the most mature material for the treatment of intracranial aneurysm by blood vessel.
