Abstract

Aneurysm of the pedal arteries is uncommon. Dorsalis pedis aneurysms are a clinically rare phenomenon. We present a case of traumatic fusiform aneurysm of the dorsalis pedis artery in an otherwise well 53-year-old Caucasian man. Initial history was suggestive of micro-embolic disease to the medial toes of the left foot and on examination pulses were palpable throughout the lower limbs with a strong, palpable dorasalis pedis pulse. Ankle brachial pressure indexes were normal but reduced toe pressures to the left toes. Colour flow duplex imaging revealed aneurysmal dilation, involving all layers of artery wall, with irregular intraluminal thrombus across a 16-mm segment. Subsequent CTA run-off revealed all vessels were patent in the left lower limb. Due to concerns over further embolisation, our patient underwent successful ligation of the his dorsalis pedis. He had an uneventful post-operative recovery.
