"Sandal strap" trauma and atherosclerosis are dual pathologies leading to bilateral true aneurysms of the dorsalis pedis arteries.

Abstract

True aneurysm of the dorsalis pedis artery is rare. To our best knowledge, only 19 cases have been reported in the literature with one case of bilateral involvement. We describe an unusual case of simultaneous, bilateral true aneurysms of the dorsalis pedis arteries due to chronic mild trauma from dorsally positioned sandal straps with secondary atherosclerotic change. This is the first such case reported. Symptomatic aneurysms are at risk for thrombosis or embolization, and surgical management is recommended. In our case, both aneurysms were resected and repaired with interposition graft of saphenous vein. The patient was symptom free at 6-month follow-up.
