Endovascular vs. open repair of popliteal artery aneurysm: review article

Abstract The conventional treatment for a popliteal artery aneurysm is open surgery to exclude the aneurysm and revascularization of the affected limb. Over recent years, endovascular treatment has grown in popularity and has been attracting increased interest. Endovascular treatment is less invasive and associated with lower rates of morbidity, but it is expensive and patency is uncertain. The aim of this review is to compare these two treatments by analyzing the outcomes reported in primary and secondary studies. A narrative review is conducted of the literature published over the last 5 years. Six retrospective studies, two meta-analyses, one clinical trial and one Cochrane systematic review were selected. We were unable to draw firm conclusions because of small patient samples and short follow-up periods. There is no clear evidence to indicate that the outcomes of one or another elective treatment are superior. New randomized trials should be conducted to determine the role endovascular treatment has to play in management of this type of aneurysm.

摘要 腘动脉瘤（popliteal artery aneurysm）的传统治疗方案为开放手术行动脉瘤隔绝术并实施患肢血运重建。近年来，血管腔内治疗（endovascular treatment）的应用愈发普及，相关研究关注度持续提升。该治疗方式创伤更小，围手术期并发症发生率更低，但费用高昂且血管通畅性尚不确定。本综述旨在通过分析原始研究与二次研究报告的结局指标，对比两种治疗方案的优劣。本次研究为叙事性综述，纳入近5年发表的相关文献，最终筛选纳入6项回顾性研究、2项荟萃分析、1项临床试验及1篇Cochrane系统综述。由于患者样本量较小且随访周期较短，本研究无法得出确定性结论。目前尚无明确证据表明任一择期治疗方案的结局更优。未来应开展新的随机对照试验，以明确血管腔内治疗在该类动脉瘤管理中的应用价值。
