摘要To the Editor:Popliteal artery aneurysms (PAAs) account for nearly 70% of peripheral artery aneurysms.[1] Most PAAs are asymptomatic.Symptomatic PAAs typically present with lower extremity ischemia caused by acute or chronic thrombosis and distal embolization.Rupture of PAAs and popliteal artery pseudoaneurysms are rarely reported.[2] In this study,PAA-induced emergencies are classified as acute hemorrhagic and ischemic complications.Compared with uncomplicated PAAs with almost no limb loss and perioperative mortality,these acute complications can make management of PAAs extremely challenging,even for an experienced vascular surgeon,as evidenced by a significant risk of amputation and death in previous reports.
