摘要

简介:本研究分析了使用AFX支架对非常狭窄的肾下主动脉病变进行血管内动脉瘤修复(EVAR)后的患者预后。方法:收集2013年1月至2020年5月收治的35例腹主动脉瘤(AAA)(48.6%)或穿透性主动脉溃疡(PAU)(51.4%)患者的病历资料,其中主动脉分叉极窄。应用Kaplan-Meier方法估计患者的生存、无内皮渗漏(EL)和肢体闭塞。结果:平均随访时间为20.4±22.8个月。平均主动脉分叉直径15.8±2.2 mm。技术成功率为100%,无手术相关死亡发生。随访30天内发生2例II型el。在同一例患者中,我们在4个月时观察到1例常见髂动脉狭窄,在54个月时观察到1例III型EL,两者都需要再次干预。患者总生存率为95±5% (AAA: 100%;PAU: 89±10%),肢体无闭塞性94±5% (AAA: 91±9%;PAU: 100%), II型EL的自由度为94±4% (AAA: 88±8%;PAU: 100%), III型EL自由度为83±15% (AAA: 80±18%;PAU: 100%)在随访期结束时。结论:非常窄的主动脉分叉可能使患者在EVAR后易发生手术相关并发症。我们的结果表明在这种情况下使用AFX支架是安全的。尽管与AAA相比,PAU的总体短期和长期手术相关的患者结果似乎更令人满意。

Use of the AFX Stent Graft in Patients with Extremely Narrow Aortic Bifurcation: A Multicenter Retrospective Study.

Introduction: This study analyzed the patient outcomes following endovascular aortic aneurysm repair (EVAR) for infrarenal aortic pathologies with very narrow aortic bifurcations using the AFX stent graft.

Methods: The data was retrieved from the archived medical records of 35 patients treated for abdominal aortic aneurysm (AAA) (48.6%) or penetrating aortic ulcer (PAU) (51.4%) with very narrow aortic bifurcation between January 2013 and May 2020. Patient survival, freedom from endoleak (EL), and limb occlusion were estimated applying the Kaplan-Meier method.

Results: The mean follow-up time was 20.4 ± 22.8 months. The mean aortic bifurcation diameter was 15.8 ± 2.2 mm. Technical success was 100%, and no procedure-related deaths occurred. Two type II ELs occurred within 30-day follow-up. We observed one common iliac artery stenosis at four months and one type III EL at 54 months in the same patient, both of which required re-intervention. Overall patient survival was 95 ± 5% (AAA: 100%; PAU: 89 ± 10%), freedom from limb occlusion was 94 ± 5% (AAA: 91 ± 9%; PAU: 100%), freedom from type II EL was 94 ± 4% (AAA: 88 ± 8%; PAU: 100%), and freedom from EL type III was 83 ± 15% (AAA: 80 ± 18%; PAU: 100%) at the end of the follow-up period.

Conclusions: Very narrow aortic bifurcations may predispose patients to procedure-related complications following EVAR. Our results suggest a safe use of the AFX stent graft in such scenarios. The overall short- and long-term procedure-related patient outcomes are satisfying albeit they may seem superior for PAU when compared to AAA.
