After exclusion of popliteal artery aneurysms (PAAs) through bypass surgery, there is a risk of persistent flow through collaterals and growth of the excluded aneurysmal sac. This study was conducted to evaluate this risk at long-term follow-up.
Sixty-five PAAs treated by proximal and distal ligation and bypass grafting with reversed autologous vein in 52 patients (1998-2010) were retrospectively reviewed.
Mean follow-up was 41 months (range, 1-144 months). Five aneurysms showed residual flow (8%). One of these aneurysms had increased in size, 36 months postoperatively. This aneurysm underwent an embolization procedure after which no flow or further enlargement was demonstrated.
In this study, the risk of persistent flow in a PAA excluded by proximal and distal ligation and bypass is low. Still, considering this risk and its possible complications, follow-up by duplex ultrasound in all patients until up to more than 10 years postoperatively is recommended.
通过旁路手术排除腘动脉瘤（PAA）后，存在通过侧支持续血流以及被排除的动脉瘤囊生长的风险。本研究旨在评估长期随访时的这种风险。
回顾性分析了1998年至2010年期间52例患者中65个接受近端和远端结扎及自体静脉逆向旁路移植术治疗的腘动脉瘤。
平均随访41个月（范围1至144个月）。5个动脉瘤显示有残余血流（8%）。其中1个动脉瘤在术后36个月时增大。该动脉瘤接受了栓塞治疗，之后未显示有血流或进一步增大。
在本研究中，通过近端和远端结扎及旁路排除的腘动脉瘤持续血流风险较低。尽管如此，考虑到这种风险及其可能的并发症，建议对所有患者进行双功超声随访直至术后10多年。
