A Case of Infected Popliteal Aneurysm Treated by Resection and Revascularisation Simultaneously

Abstract

A 52-year-old man presented with swelling and pain in the left popliteal fossa, and transferred from previous hospital on the basis of the diagnosis of left popliteal aneurysm. On admission, he had fever and marked swelling, redness and tenderness in the left poplieal fossa. Blood examination showed high inflammatory reaction. Enhanced CT showed left popliteal aneurysm and fluid collection around the aneurysm. We diagnosed impending rupture of infected popliteal aneurysm and performed emergency operation. First we removed aneurysm and performed debridement of infected tissue via posterior approach, and wound was closed. Second revascularization was done via medial approach. Culture of the aneurismal wall and pus revealed Staphylococcus aureus infection. Postoperatively infectious signs showed rapid improvement by the adequate antibiotic therapy and any complication was not detected.
