title: Mycotic aneurysm of the bilateral tibioperoneal trunks associated with bacterial endocarditis: a case report.
abstract: Since antibiotics have been widely used in the treatment of bacterial endocarditis, mycotic aneurysms caused by septic emboli have become extremely rare. We report the case of a 34-year-old man who had mycotic aneurysms in the tibioperoneal trunks of both legs six weeks after he had a mitral valve replacement due to Streptococcus viridans endocarditis. Color Doppler sonography was used to diagnose pseudoaneurysms in both legs. Surgical treatment included the closures of the orifices of both aneurysms in both legs and arterial reconstructions were not required. In the literature, however, the location of mycotic aneurysms in peripheral arteries related to endocarditis were usually reported to be in the upper extremities or femoral arteries. Thus, we present the extremely rare case of mycotic aneurysms because the aneurysms occurred in the infrapopliteal vessel and developed in both legs.
