目的 :评价机械可脱式弹簧圈 (MechanicalDetachableSpiral,MDS)栓塞治疗颅内动脉瘤。方法 :对 1995年 3月～ 1998年 7月利用MDS栓塞的 64例 66个颅内动脉瘤进行回顾性分析。结果 :66个动脉瘤中 ,10 0 %栓塞的 2 5个 ,占 3 7 9% (2 5 /66) ;95 %的 19个 ,占 2 8 8% ;90 %的 11个 ,占 16 7% ;80 %的 6个 ,占 9 1% ;<80 %的 5个 ,占 7 6%。 5 5个 (83 3 % )动脉瘤达 90 %以上栓塞。死亡 2例 (3 1% ) ,永久并发症 3例 (4 7% )。结论 :应用MDS进行囊内栓塞 ,是治疗颅内动脉瘤安全有效的方法之一 OBJECTIVE: To evaluate the mechanical Detachable Spiral (MDS) embolization for the treatment of intracranial aneurysms. Methods: A retrospective analysis was performed on 64 cases of 66 intracranial aneurysms using MDS embolization from March 1995 to July 1998. Results: Of the 66 aneurysms, 25 (10/95) were embolized, accounting for 95% of the total, accounting for 28.8% (95%); 11 (90%) accounting for 16.7% %; 80% of the 6, accounting for 9 1%; <80% of the 5, accounting for 76%. Fifty-five (83.3%) aneurysms achieved more than 90% embolization. Two deaths (31%) and three permanent complications (47%) occurred. Conclusions: The application of MDS for intracapsular embolization is one of the safe and effective methods for the treatment of intracranial aneurysms
