To evaluate the efficacy of endovascular repair of popliteal artery aneurysms (PAAs) with a wire-interwoven nitinol stent.
This is a prospective, descriptive, and analytical study. From January 2016 to December 2018, 28 consecutive patients (29 lower limbs) were treated for a PAA with the deployment of the Supera stent (Abbott Vascular, Illinois). Twenty-three (79.3%) PAAs were asymptomatic; 6 (20.7%) presented with symptoms. The mean diameter and length of the aneurysm were 26.8 mm (20-40 mm) and 47.1 mm (23-145 mm) respectively. The primary endpoint was the prevention of embolic symptoms. The secondary endpoints were aneurysm exclusion, aneurysm diameter decrease, freedom from reintervention, and preservation of preoperative runoff vessels.
Technical success was 100%, with a median of 2.4 run-off vessels at completion angiography, without any loss of run-off vessels. A double Supera stent was deployed in 10 cases. At completion angiography, a median of 2.4 runoff vessels were present, without any loss of runoff vessels. The mean follow-up time was 24.3 (12-35) months. Primary endpoints were reached in 100% of the cases and vessels run off was preserved in all cases. In 2 PAAs, complete sac thrombosis was witnessed at 6-month follow-up, while at 12-month follow-up, it was seen in 10 of 29 (34.4%) limbs. In all the other cases the diameter of the aneurysm remained stable, with a freedom from sac enlargement of 100%. No fractures or stent thromboses were detected.
For endovascular repair of PAAs, the use of a thick interwoven-wire stent, that could work like a multilayer flow modulator showed encouraging mid-term results with no cases of stent fracture, occlusion or aneurysm increase.
评估使用编织型镍钛合金支架进行腘动脉动脉瘤（PAAs）腔内修复的疗效。
这是一项前瞻性、描述性和分析性研究。2016 年 1 月至 2018 年 12 月，连续 28 例（29 条下肢）患者因 PAA 接受 Supera 支架（雅培血管，伊利诺伊州）治疗。23 例（79.3%）PAA 无症状；6 例（20.7%）有症状。动脉瘤的平均直径和长度分别为 26.8mm（20-40mm）和 47.1mm（23-145mm）。主要终点是预防栓塞症状。次要终点是动脉瘤排除、动脉瘤直径减小、免于再次干预以及术前流出血管的保留。
技术成功率为 100%，完成血管造影时中位数为 2.4 条流出血管，没有任何流出血管丢失。10 例患者植入双 Supera 支架。完成血管造影时，中位数为 2.4 条流出血管，没有任何流出血管丢失。平均随访时间为 24.3（12-35）个月。100%的病例达到了主要终点，所有病例都保留了流出血管。在 2 例 PAA 中，6 个月随访时观察到完全囊血栓形成，而在 12 个月随访时，29 例（34.4%）中有 10 例观察到完全囊血栓形成。在所有其他病例中，动脉瘤直径保持稳定，无囊扩大，扩大率为 100%。未发现支架断裂或支架内血栓形成。
对于 PAAs 的血管内修复，使用厚编织型编织镍钛合金支架，这种支架可以像多层流量调节剂一样工作，显示出令人鼓舞的中期结果，没有支架断裂、闭塞或动脉瘤增大的病例。
