This study was designed to evaluate the efficacy and safety of CT-guided embolization of internal iliac artery aneurysm (IIAA) after repair of abdominal aortic aneurysm by transretroperitoneal approach using the lidocaine injection technique to iliacus muscle, making window for safe needle path for three patients for whom CT-guided embolization of IIAA was performed by transretroperitoneal approach with intramuscular lidocaine injection technique. Transretroperitoneal access to the IIAA was successful in all three patients. In all three patients, the IIAA was first embolized using microcoils. The aneurysmal sac was then embolized with glue and coils without complication. With a mean follow-up of 7 months, the volume of the IIAAs remained stable without residual endoleaks. Transretroperitoneal CT-guided embolization of IIAA using intramuscular lidocaine injection technique is effective, safe, and results in good outcome.
本研究旨在评估经腹膜后途径修复腹主动脉瘤后，采用利多卡因注射入髂肌的技术为3例患者经腹膜后途径进行CT引导下髂内动脉瘤（IIAA）栓塞术创建安全穿刺路径窗口时，CT引导下栓塞IIAA的疗效和安全性。所有3例患者经腹膜后途径成功到达IIAA。在所有3例患者中，首先使用微线圈栓塞IIAA。然后用胶水和线圈栓塞瘤囊，无并发症发生。平均随访7个月，IIAA的体积保持稳定，无残余内漏。采用肌肉内注射利多卡因技术经腹膜后CT引导下栓塞IIAA是有效、安全的，且效果良好。
