Two Surgical Cases of Dorsalis Pedis Artery Aneurysm

Abstract

Dorsalis pedis artery aneurysms represent an extremely rare type of peripheral aneurysm, and there is a lack of consensus regarding the necessity of revascularization after aneurysm excision. We report two cases of dorsalis pedis artery aneurysms treated surgically at our hospital, together with a literature review. Case 1: The patient presented with a saccular aneurysm; we performed end-to-end anastomosis for revascularization after aneurysm excision. Contrast-enhanced computed tomography (CT) performed 4 years postoperatively revealed occlusion of reconstructed vessels and the development of collateral circulation. Case 2: The patient presented with a fusiform aneurysm; we did not perform reconstruction using end-to-end anastomosis after aneurysm excision. Preoperative contrast-enhanced CT confirmed adequate blood circulation to the plantar arch via the arcuate artery, and intraoperative findings indicated that revascularization was not necessary. The patient did not show any postoperative peripheral blood flow abnormalities. We report two surgical cases of dorsalis pedis artery aneurysms, which represent an extremely rare type of peripheral aneurysm.
