Open surgical repair of true saccular aneurysm of dorsalis pedis artery using a reversed great saphenous vein bypass graft.

True aneurysms of the dorsalis pedis artery (DPA) are very rare phenomena with no obvious pathophysiology. Prompt diagnosis and treatment are important due to the high risk of thrombosis, distal embolization, hemorrhage, and rupture. We present a case of a true DPA saccular aneurysm in a 58-year-old man and highlight the feasibility of using a reversed great saphenous vein bypass graft in specifically treating true DPA aneurysms. Our treatment resulted in near-immediate resolution of the patient's foot pain and mass without complications and maintaining arterial patency.
