目的 探讨颅内动脉瘤囊内栓塞结果的影像学判断标准。 方法 6名专科医师根据动脉瘤栓塞后血管造影不显影为 10 0 %、瘤颈少许残留为 95 %、瘤颈残留为 90 %、瘤颈残留并有少许瘤体残留为 80 %和少部分瘤体残留为 <80 %的栓塞判断标准 ,对 1995年 3月至 1999年 7月用机械可脱式弹簧圈和 (或 )电解可脱式弹簧圈囊内栓塞的 12 0例 (12 1个 )动脉瘤的血管造影片进行评价 ,并分析该标准的合理性、可行性和局限性。 结果 12 1个动脉瘤中 ,栓塞 <80 %、80 %、90 %、95 %和10 0 %的动脉瘤数依次分别为 10 (8 3% )、15 (12 4% )、16 (13 2 % )、2 7(2 2 3% )和 5 3(4 3 8% )个 ,栓塞80 %～ 10 0 %动脉瘤的平均栓塞率 (94 6 4± 6 80 ) %。不同医师间的栓塞结果评判相互符合性好。 结论 该标准简易可行 ,符合临床实际 ;但栓塞百分比的数值规定有一定的任意性 ,对随访结果的临床指导意义有待进一步探讨。
Objective To investigate the imaging criteria of intracapsular embolization in intracranial aneurysms. Methods According to the angiography of aneurysm embolization, 6 specialists did not develop a contrast of 10%, 95% of tumor neoplasm remained, 90% of neoplasm neck remained, and some of neoplasm remained with some tumor remaining 80% and a few neoplasms Body residue was <80% of the criteria for embolization. Between March 1995 and July 1999, 120 cases (121) embolized with a mechanically releasable coil and / or electrolytically detachable coil were included. The aneurysm angiogram was evaluated and the rationality, feasibility and limitations of the standard were analyzed. Results Among the 12 aneurysms, the number of aneurysms with embolization <80%, 80%, 90%, 95% and 100% were 10%, 15%, 16% %), 27 (23.3%) and 53.3% (48.3%) embolization. The mean embolization rate of the aneurysms from 80% to 100% in the embolization group was (94 6 4 ± 6 80)%. Evaluation of embolism among different physicians is consistent with each other. Conclusion The standard is simple and feasible, which is in line with clinical practice. However, the numerical value of embolism percentage has a certain degree of arbitrariness. The clinical significance of follow-up results remains to be further explored.
