Aneurisma da artéria dorsal do pé: relato de caso e revisão da literatura Aneurysm of the dorsalis pedis artery: case report and literature review

The present article reports a case of a male child with aneurysm of the dorsalis pedis artery. Diagnosis was confirmed by duplex scanning and pathoanatomical examination. End-to-end anastomosis was performed. Six months later, the lesion reappeared. A new duplex scan showed integrity of the anastomosis and revealed another aneurysm immediately close to this one. An angiographic study was performed and showed complete plantar arch. The aneurysm was resected and the dorsal foot artery was ligated. A pathological examination evidenced arterial dissection after anastomosis. During a six-month follow-up period after the second surgery, no recurrence was noted. Most of the published case reports related to pseudoaneurysms. True aneurysms are relatively rare. A discussion about the etiology, epidemiology and treatment of this type of aneurysm is also presented.
