Abstract
Popliteal artery aneurysms (PAAs) can recur because of persistent perfusion of the excluded aneurysm sac. However, recurrences despite exclusion bypass is rare. We report the case of a 76-year-old man presenting with a second recurrence of PAA with proximal extension involving the distal superficial femoral artery, occurring more than 30 years after initial ligation and bypass. He underwent a third operation involving repeat aneurysm sac excision and ligation of collateral geniculate branches. This case highlights the rarity and challenges of managing recurrent PAA, emphasizing the importance of meticulous collateral control during the index procedure and lifelong surveillance following repair.
