To evaluate the success of endoleak repair using translumbar (TL) endoleak embolization compared with a transarterial (TA) technique that involves embolization of the endoleak cavity itself in addition to the feeding artery.
Eighty-four patients (mean age, 78.2 years; age range, 58-94 years) with type 2 endoleaks were included in this retrospective study. Patients underwent either TL endoleak embolization or TA embolization between January 2002 and December 2007. TA embolization involved entering the endoleak cavity through the inferior mesenteric or lumbar artery. Both the endoleak cavity and the feeding artery were then embolized by using coils through a microcatheter. TL embolizations were performed by using standard technique with coils and n-butyl cyanoacrylate as the embolization agents. Clinical success was defined as the absence of an endoleak and/or aneurysm enlargement at follow-up CT angiography. Statistical comparison was performed with the Fisher exact test.
Endoleak repair was successful in 72% (45/62) of the TL embolizations and 78% (18/23) of the TA embolizations, with a mean follow-up of 18.7 months (range, 1-84 months). There was no significant difference in clinical success between the two groups (P = .41). There were two (3.2%) complications in the TL group and no complications in the TA group.
The effectiveness of the TA endoleak embolization technique, which involves embolizion of the endoleak cavity and the feeding artery, is similar to that of TL embolization for treatment of type 2 endoleaks.
评估经腰椎（TL）腔内漏栓塞与经动脉（TA）技术治疗 2 型内漏的效果，后者除了栓塞内漏腔本身外，还栓塞供血动脉。
本回顾性研究纳入 84 例（平均年龄 78.2 岁；年龄范围 58-94 岁）2 型内漏患者。这些患者于 2002 年 1 月至 2007 年 12 月期间分别接受 TL 内漏栓塞或 TA 栓塞治疗。TA 栓塞治疗包括经肠系膜下或腰动脉进入内漏腔。通过微导管，使用微导管将线圈栓塞到内漏腔和供血动脉。TL 栓塞治疗采用标准技术，使用线圈和 n-丁基氰基丙烯酸酯作为栓塞剂。临床成功定义为随访 CT 血管造影显示无内漏和/或动脉瘤增大。采用 Fisher 精确检验进行统计学比较。
TL 栓塞组 72%（45/62）和 TA 栓塞组 78%（18/23）的内漏修复成功，平均随访时间为 18.7 个月（范围 1-84 个月）。两组临床成功率无显著差异（P=0.41）。TL 组有 2 例（3.2%）并发症，TA 组无并发症。
TA 内漏栓塞技术，即栓塞内漏腔和供血动脉，治疗 2 型内漏的效果与 TL 栓塞相似。
