Abstract
Aneurysm of the dorsalis pedis artery are rare vascular entities, producing a focal soft tissue mass in the dorsal foot. A case of dorsalis pedis artery pseudoaneurysm is reported. The patient was a 69-year-old woman. She had noticed a tumor on the dorsum on the right foot 4 years previouly and consulted our hospital complaining of pulsatile mass with uncomfortableness. We diagnosed this tumor as aneurysm at dorsalis pedis artery by duplex doppler ultrasound and CTA. It was thought that the etiology of the dorsalis pedis artery pseudoaneurysm was traumatic or iatrogenic (cannulation of a dorsal vein of foot, during the previous operation of cerebral aneurysm). The postoperative course was uneventful. The patient was discharged on 7th day after the operation. A review of literature in Japan is also presented.
