在 1997 年 3 月至 2003 年 1 月期间，对 86 名接受标准铂弹簧圈栓塞治疗的 88 个脑囊动脉瘤的患者进行了研究，研究了体积栓塞率 (VER)、弹簧圈所占动脉瘤体积的百分比以及铂弹簧圈血管内治疗后动脉瘤稳定性之间的相关性。对 62 个动脉瘤进行了放射学随访，其中立即闭塞率超过 70%术后血管造影超过 6 个月。术后立即评估发现，14 个小动脉瘤 (< 4 mm) 中的 12 个、38 个中动脉瘤中的 12 个 (4- < 10 mm) 和 10 个大动脉瘤 (>= 10 mm) 中的 2 个具有高 (>= 25%) VER。此外，40 个小（= 4mm）动脉瘤中有 22 个的 VER 较高。弹簧圈栓塞后 6 个月对 57 个动脉瘤进行评估，发现 25 个高 VER 动脉瘤中有 2 个出现再通，32 个低 VER 动脉瘤中有 21 个出现再通。
The correlation between volume embolization ratio (VER), the percentage of aneurysm volume occupied by coils, and aneurysm stability after endovascular treatment with platinum coils was studied in 86 patients who underwent embolization of 88 cerebral saccular aneurysms with standard platinum coils between March 1997 and January 2003. Radiographic follow up was possible of 62 aneurysms with greater than 70% obliteration on immediate post-procedure angiograms for more than 6 months. Immediate post-procedure evaluation found that 12 of 14 small (< 4 mm), 12 of 38 medium (4- < 10 mm), and two of 10 large (>= 10 mm) aneurysms had high (>= 25%) VER. In addition, the VER was high in 22 of 40 aneurysms with small (= 4mm). Evaluation of 57 aneurysms at 6 months after coil embofization found recanalization in two of 25 aneurysms with high VER and 21 of 32 with low (
