title: Popliteal artery aneurysm: two case reports of acute lower limb ischaemia.
abstract: Two cases of thrombosed popliteal artery aneurysm causing acute ischaemia were described. This report emphasises the importance of early diagnosis and surgical intervention of this condition. We then present a brief review of clinical presentation and current management of popliteal artery aneurysm. Popliteal artery aneurysm commonly first present as acute lower limb ischaemia secondary to thrombo-embolism. Failure to recognise this limb-threatening condition can lead to delay in treatment and even limb loss. It is therefore important to increase awareness of this condition. Popliteal artery aneurysm warrants early surgical intervention, even in an asymptomatic stage because of its potential for serious complications.
