Giant, Metachronous Bilateral Dorsalis Pedis Artery True Aneurysms

This report is the first to describe the clinical, radiographic, operative, and pathologic findings associated with large, bilateral dorsalis pedis artery true aneurysms in a single patient. A 61-year-old African American woman complained of difficulty in wearing shoes. She had a moderately firm, nontender, pulsatile mass on the dorsum of her right foot. Computed tomography and angiography confirmed dorsalis pedis artery aneurysm with sufficient collateralization. She underwent resection without reconstruction. Pathologic analysis revealed a true aneurysm (8 × 5.3 × 4.1 cm3) containing intralumenal thrombus. Treatment for small symptomatic and large dorsalis pedis artery aneurysms remains resection with or without reconstruction.
