A Surgically Treated Popliteal Artery Aneurysm Concomitant with Advanced Inflammation

Abstract

A 65-year-old man was referred for a popliteal artery aneurysm with severe knee pain. Computed tomography revealed a popliteal artery aneurysm in the right knee area. His laboratory data showed severe inflammatory findings, but not bacteremia. Semi-urgent surgery was performed because of uncontrollable pain in the right knee area, of a successful autologous saphenous vein graft replacement of the popliteal artery aneurysm. The pathological findings of the resected tissue revealed inflammation without bacterial infection. When the clinical course was taken into consideration, inflammation of the popliteal artery had progressed to a popliteal artery aneurysm. This patient was discharged without any neurological deficit.
