Summary Radial artery pseudoaneurysms are rare clinical entities usually occurring after penetrating trauma or iatrogenic injury. The radial artery is the least common location for peripheral artery pseudoaneurysms, and no clear standard of treatment exists. We present a case of an adolescent male who developed a radial artery pseudoaneurysm after slitting his wrists. Using a single incision, the radial artery pseudoaneurysm was excised and repaired using a reversed venae comitantes interposition graft. This single incision technique for radial artery pseudoaneurysm repair preserves the dual arterial supply to the hand, which is of particular importance in young patients.
