A case of traumatic pseudoaneurysm of the dorsalis pedis artery

ABSTRACT

An aneurysm occurs in association with trauma, atherosclerosis, infection and congenital diseases. Among these, the traumatic arterial aneurysms developed from blunt trauma, crushing injury, perforation, and lacerations of vessels. Generally, most traumatic arterial aneurysms are false type, so called pseudoaneurysm. A pseudoaneurysm occurs by incomplete laceration of the vessel wall or partial division of the vessel. The vascular injury will make hematoma and fibrosis of neighboring tissues. After two to eight weeks post-trauma, the organized hematoma is liquefied and the fibrous tissue acts as an aneurysmal sac. We have experienced a case of dorsalis pedis artery pseudoaneurysm associated with arterial cannulation. So, we report a case of traumatic pseudoaneurysm with a review of literature.
