To evaluate the use of covered stent-grafts in the endovascular treatment (ET) of popliteal artery aneurysms (PAAs).
A retrospective analysis was conducted over a period of 52 months in 18 consecutive patients (17 men; mean age +/- SD, 70 years +/- 11) undergoing ET of PAAs with the Viabahn endograft in a single center. Patient symptoms, aneurysm characteristics, technical outcomes, complications, and follow-up were assessed.
Aneurysm diameters ranged from 12 to 51 mm with a mean of 30 mm (+/-11). Thirteen aneurysms (72.2%) were partially thrombosed and 12 patients (66.6%) had symptoms of lower limb ischemia at presentation (11 chronic and one acute). The technical success rate was 94%. Intraprocedural emboli and endoleak occurred in one and two patients, respectively. Fourteen patients were available for follow-up after successful treatment, with a mean follow-up time of 15 months (range, 7-37 months). All stent-grafts were patent after 1 month, with no mortality or limb loss. The primary patency rate with complete exclusion of the aneurysm at 6 months was 86%. Pre- and postprocedural noninvasive arterial studies were available in 10 patients, demonstrating improvement of the ankle-brachial index from 0.96 +/- 0.41 to 1.17 +/- 0.18, respectively (P = .06).
Endovascular stent-graft repair of PAAs is a feasible treatment option. However, further follow-up studies regarding the durability of results are required.
评估带膜支架移植物在治疗腘动脉瘤（PAAs）中的应用。
在一家中心，对连续 18 例（17 名男性；平均年龄 +/- 标准差，70 岁 +/- 11 岁）接受 Viabahn 支架移植物治疗的 PAAs 患者进行了 52 个月的回顾性分析。评估患者症状、动脉瘤特征、技术结果、并发症和随访情况。
动脉瘤直径为 12 至 51mm，平均 30mm（+/-11）。13 个动脉瘤（72.2%）部分血栓形成，12 例患者（66.6%）有下肢缺血症状（11 例慢性，1 例急性）。技术成功率为 94%。1 例术中发生栓塞，2 例发生内漏。成功治疗后 14 例患者可进行随访，平均随访时间为 15 个月（7-37 个月）。所有支架移植物在 1 个月后均通畅，无死亡或肢体丧失。6 个月时完全排除动脉瘤的主要通畅率为 86%。10 例患者术前和术后均进行了非侵入性动脉研究，分别显示踝肱指数从 0.96 +/- 0.41 提高到 1.17 +/- 0.18（P =.06）。
腘动脉瘤的腔内支架移植物修复是一种可行的治疗选择。然而，需要进一步的随访研究来评估结果的耐久性。
