Post-traumatic arterial injuries are often reported in crushing or penetrating gun-shot injuries that include massive soft tissue damage. In most cases, the injured arteries are treated with early repair or reconstruction surgery. When there is a delayed in diagnosis, a pseudoaneurysm might be detected several weeks or months after the trauma. Pseudoaneurysms after femoral fracture are usually detected in the superficial femoral arteries, but rarely in the very deep femoral arteries, which are protected by the vastus medialis. There are many reports on post-traumatic pseudoaneurysms, most of which are in the superficial femoral arteries, and there are few reports with normal findings in an early angiogram. We report a pseudoaneurysm of the deep femoral artery with a normal angiogram in the early stage that was diagnosed and treated 4weeks after the trauma.
