Thirty-three consecutive patients with 34 TVIAs were prospectively recruited and treated with endovascular techniques. The volume of TVIAs and the required length of coils were calculated by the AngioSuite software before embolization. The treatment efficacy of TVIAs was assessed using the Raymond scale (Rs) and the modified Rankin scale (mRs).
Of the 34 aneurysms with an average volume of 7.16 mm, 13 aneurysms were treated with sole coil embolization, 19 by stent-assisted embolization, and 2 by balloon-assisted embolization. The average coil length was 5.32 cm, and the average packing density was 41.21%. The immediate DSA showed that total occlusion (Rs = 1) was achieved in 15 aneurysms, subtotal (Rs = 2) in 9, and partial (Rs = 3) in 11. Total occlusion was achieved in 30 aneurysms and subtotal in the other 4 aneurysms at 6-month follow-up. Baseline volume and diameter of aneurysms were significantly correlated with the coil length ( = 0.801, < 0.001; = 0.711, < 0.001).
Coil embolization of TVIAs was easy to achieve high packing density. According to the data from AngioSuite, relative few coils can increase the safety in procedure and stenting may reduce risk of aneurysmal recurrence.
前瞻性招募了 33 例连续的 34 个眼动脉段动脉瘤患者，并采用血管内技术进行治疗。在栓塞前，通过 AngioSuite 软件计算眼动脉段动脉瘤的体积和所需的线圈长度。采用 Raymond 分级（Rs）和改良 Rankin 分级（mRs）评估眼动脉段动脉瘤的治疗效果。
在平均体积为 7.16mm 的 34 个动脉瘤中，13 个动脉瘤单独采用线圈栓塞治疗，19 个动脉瘤采用支架辅助栓塞治疗，2 个动脉瘤采用球囊辅助栓塞治疗。平均线圈长度为 5.32cm，平均填塞密度为 41.21%。即刻 DSA 显示，15 个动脉瘤达到完全闭塞（Rs=1），9 个动脉瘤达到次全闭塞（Rs=2），11 个动脉瘤达到部分闭塞（Rs=3）。6 个月随访时，30 个动脉瘤达到完全闭塞，4 个动脉瘤达到次全闭塞。动脉瘤的基线体积和直径与线圈长度显著相关（ = 0.801，<0.001； = 0.711，<0.001）。
眼动脉段动脉瘤的线圈栓塞容易达到高填塞密度。根据 AngioSuite 的数据，相对较少的线圈可以增加手术安全性，支架置入可能降低动脉瘤复发的风险。
