BACKGROUND/AIM: Popliteal artery aneurysms (PAAs) are abnormal bulgings, which account for 70% of all peripheral artery aneurysms. They are usually asymptomatic. In this study, we present our long-term results of endovascular stent grafts in the treatment of PAA in the light of literature data.
A total of 63 legs of 63 patients with PAA, who were treated with endovascular techniques in our clinic between July 2010 and July 2019, were retrospectively analyzed. All patients underwent color Doppler ultrasound (DUS), magnetic resonance angiography (MRA), or computed tomography angiography (CTA) to identify the diameter and length of PAAs, vessel tortuosity, the presence and degree of thrombus, and diameter in the healthy landing zone and to visualize tibioperoneal vascular structures. A Viabahn stent graft was inserted in all patients.
57 patients (90.5%) were males with a mean age of 76.35 ± 7 years. 24 patients (38.1%) were symptomatic, while 11 patients (17.5%) had a concomitant abdominal aortic aneurysm (AAA). The mean follow-up period was 46.05 ± 25.01 months. The primary patency rate was 79.3%. A graft thrombosis was observed in 13 patients (20.6%) during a mean follow-up period of 8.31 ± 5.91 months. The number of distal arteries was significantly lower in the patients with thrombosis than those without.
Endovascular treatment of PAA using stentgrafts is safe in selected cases. However, it is reasonable to avoid endovascular treatment due to an increased risk for thrombosis in patients with a low number of patent distal arteries or impaired distal flow.
背景/目的：腘动脉动脉瘤（PAAs）是异常膨出，占所有外周动脉动脉瘤的 70%。它们通常无症状。在这项研究中，我们根据文献数据报告了我们用血管内支架移植物治疗 PAA 的长期结果。
回顾性分析了 2010 年 7 月至 2019 年 7 月在我院接受血管内技术治疗的 63 例 PAA 患者的 63 条腿。所有患者均行彩色多普勒超声（DUS）、磁共振血管造影（MRA）或计算机断层血管造影（CTA）检查，以确定 PAA 的直径和长度、血管迂曲、血栓的存在和程度以及健康着陆区的直径，并可视化胫腓血管结构。所有患者均植入 Viabahn 支架移植物。
57 例患者（90.5%）为男性，平均年龄 76.35±7 岁。24 例（38.1%）有症状，11 例（17.5%）合并腹主动脉瘤（AAA）。平均随访时间为 46.05±25.01 个月。一期通畅率为 79.3%。在平均 8.31±5.91 个月的随访中，13 例（20.6%）患者出现移植物血栓形成。血栓形成患者的远端动脉数量明显低于无血栓形成患者。
在选择的病例中，使用支架移植物治疗 PAA 是安全的。然而，对于远端动脉通畅数量较低或远端血流受损的患者，由于血栓形成风险增加，避免血管内治疗是合理的。
