At presentation there was a 2 cm pulsatile mass over the DPA (Fig. 1), with no thrill or bruit.

Duplex ultrasound scanning and magnetic resonance images showed a 20x18 mm right DPA aneurysm (Fig. 2A). Lower limb angiography confirmed the diagnosis (Fig. 2B).
(A) The per-operative image shows a pseudo-aneurysm of approximately 2 cm in diameter originating from the dorsalis pedis artery. (B) The arterial defect causing the false aneurysm.

The DPA aneurysm was dissected free and controlled proximally and distally with vessel loops (Fig. 3A). An arterial defect of approximately 5 mm was detected as the cause of the pseudo-aneurysm (Fig. 3B).

After aneurysm resection, there was sufficient length to enable end to end anastomosis with a 7-0 prolene continuous suture between the proximal and distal ends of the remaining DPA (Fig. 4).
