Spontaneous Nonaneurysmal Rupture of Posterior Tibial Artery in a Patient with Bacteremia

Abstract

We report a case of spontaneous nonaneurysmal rupture of posterior tibial artery in a patient with bacteremia. The patient was an 82-year-old male. He felt slight pain with his left calf after admission for enterocolitis and Escherichia coli bacteremia. Ultrasonography showed suspected deep vein thrombosis without aneurysms, and heparinization was started. Eighteen days after admission, his painful left calf was swollen with a sudden pulsation. Computed tomography and ultrasonography showed suspected pseudoaneurysm of his left posterior tibial artery. However, there was no aneurysmal vascular tissue and the artery was completely ruptured. The arterial stumps were ligated without revascularization.
