A Case of Isolated Profunda Femoris Artery Aneurysm with Gait Disturbance Due to the Femoral Nerve Palsy

Abstract

Profunda femoris artery aneurysms are rare, and clinical form is various. We experienced a case of profunda femoris artery aneurysm with gait disturbance by femoral nerve compression. An 80-year-old man presented with left leg muscle weakness and gait disturbance. He was transferred from previous hospital on the basis of the suspect of femoral artery aneurysm because of a mass in left inguinal region. The enhanced CT scan showed a left profunda femoris artery aneurysm measuring 54 mm. We judged that the gait disturbance was caused by femoral nerve compression from the aneurysm. We performed graft replacement and femoral nerve release. Postoperatively the patient became ambulant by himself after improvement of the symptom from the femoral nerve compression and discharged on 9th postoperative day.
