Pseudoaneurysms of the deep femoral artery have been reported after external injury to the thigh and orthopedic surgery of the femur. We describe our experience with a case of spontaneous rupture of a deep femoral pseudoaneurysm in a woman who was receiving warfarin within the therapeutic range. She received a choledocholithotomy after a radical hysterectomy for uterine cervical cancer (stage IB1). Pulmonary embolism and deep-vein thrombosis developed after choledocholithotomy, and an inferior vena cava filter was left in place permanently. She was receiving warfarin since then. This time, the patient presented with a pseudoaneurysm of the deep femoral artery and a large hematoma in the adductor muscle of the thigh. Swelling of the thigh in this condition resembled the lower-extremity edema that occurs after pelvic lymph-node dissection. Contrast-enhanced computed tomography (CT) was useful for diagnosis of the pseudoaneurysm and evaluation of the extent of muscle damage.
