To report our midterm results of the crossover chimney technique to preserve the internal iliac artery (IIA) in patients with aortoiliac aneurysms (AIA) and isolated common iliac artery aneurysms (CIAA).
Between May 2012 and January 2014, 14 consecutive patients (mean age 77.3 years; all men) with 17 AIA, isolated CIAAs, or abdominal aortic aneurysms with short CIAs underwent elective endovascular aneurysm repair (EVAR) with the crossover chimney technique to preserve the IIA. Follow-up assessment, including computed tomographic angiography or duplex ultrasound, was performed at 1, 6, and 12 months and annually thereafter.
Technical success, defined as successful preservation of IIA without intraoperative type I or III endoleak, was 100%. Over a mean 14.3 months (range 6-21), primary patency was 92.8%. There was no early or late procedure-related mortality. Among the 17 iliac aneurysms excluded, the sac diameter significantly (at least 5 mm) decreased in 3, decreased <5 mm in 10, and did not change in 4.
The crossover chimney technique is a simple and safe alternative for IIA endovascular revascularization with high technical success and acceptable midterm patency.
报告我们采用交叉烟囱技术保留髂内动脉（IIA）治疗主髂动脉瘤（AIA）和孤立性髂总动脉瘤（CIAA）患者的中期结果。
2012年5月至2014年1月，14例连续患者（平均年龄77.3岁；均为男性），患有17例AIA、孤立性CIAA或伴有短髂总动脉的腹主动脉瘤，接受了采用交叉烟囱技术保留IIA的择期血管腔内动脉瘤修复术（EVAR）。在术后1、6和12个月以及此后每年进行随访评估，包括计算机断层血管造影或双功超声检查。
技术成功率定义为成功保留IIA且术中无I型或III型内漏，为100%。平均随访14.3个月（范围6 - 21个月），一期通畅率为92.8%。无早期或晚期与手术相关的死亡。在排除的17例髂动脉瘤中，瘤囊直径显著（至少5 mm）缩小的有3例，缩小<5 mm的有10例，无变化的有4例。
交叉烟囱技术是IIA血管腔内血运重建的一种简单且安全的替代方法，技术成功率高，中期通畅率可接受。
