To evaluate the feasibility, safety, and efficacy of embolization of internal iliac artery aneurysm (IIAA) after percutaneous direct puncture under (cone-beam) computed tomography (CT) guidance.
A retrospective case series of three patients, in whom IIAA not accessible by way of the transarterial route, was reviewed. CT-guided puncture of the IIAA sac was performed in one patient. Two patients underwent puncture of the IIAA under cone-beam CT guidance.
Access to the IIAA sac was successful in all three patients. In two of the three patients, the posterior and/or anterior division was first embolized using platinum microcoils. The aneurysm sac was embolized with thrombin in one patient and with a mixture of glue and Lipiodol in two patients. No complications were seen. On follow-up CT, no opacification of the aneurysm sac was seen. The volume of one IIAA remained stable at follow-up, and the remaining two IIAAs decreased in size.
Embolization of IIAA after direct percutaneous puncture under cone-beam CT/CT-guidance is feasible and safe and results in good short-term outcome.
评估在（锥形束）计算机断层扫描（CT）引导下经皮直接穿刺栓塞髂内动脉瘤（IIAA）的可行性、安全性和疗效。
回顾性分析了 3 例经动脉途径无法到达 IIAA 的患者。1 例患者行 IIAA 囊腔 CT 引导下穿刺，2 例患者行锥形束 CT 引导下 IIAA 穿刺。
所有 3 例患者均成功进入 IIAA 囊腔。在这 3 例患者中的 2 例中，首先使用铂金微线圈栓塞 IIAA 的后部分支和/或前部分支。1 例患者用凝血酶栓塞动脉瘤囊，2 例患者用混合胶和碘化油栓塞。未出现任何并发症。在随访 CT 上，未见动脉瘤囊显影。1 个 IIAA 的体积在随访时保持稳定，其余 2 个 IIAA 的体积减小。
在锥形束 CT/CT 引导下经皮直接穿刺栓塞 IIAA 是可行且安全的，可获得良好的短期疗效。
