Open surgical ligation of a symptomatic mycotic aneurysm of the peroneal artery

Abstract

A mycotic peroneal artery aneurysm (MPAA) is a rare diagnosis. We describe a case of a patient with active fungal endocarditis who developed right lower extremity pain. Imaging demonstrated that this patient had an MPAA. This was treated with open ligation of the peroneal artery, and decompression of the aneurysm sac was performed for symptom relief. Although a rare diagnosis, MPAA should be considered in patients with a history of endocarditis who present with leg pain.

“…Mycotic emboli causing aneurysms tend to lodge in the lower extremity and, more specifically, at the bifurcation of the common femoral artery. 4 , 5 Sites of embolization such as the TPT or more distal vessels are rare and found as case reports 6 , 7 , 8 ; a detailed listing of these cases in the literature was published by Leon et al. 9 It should be considered that the decreased incidence of these more distal PSA may be related to decreased detection rather than truly decreased frequency.…”
