An unusual case of a true aneurysm of the dorsalis pedis artery in a young man -an eight years observation

We present a case of a 21-year-old man, physically active, a few months after a torsion injury of the left ankle periodically began to have persistent problems similar in nature to Raynaud's phenomenon in the left foot, especially after exposure to cold and prolonged immobilization of the ankle, in ski shoes, for example. Initial Duplex Doppler ultrasonography revealed an abnormal lateral course of the distal segment of the left anterior tibial artery and the initial section of the dorsalis pedis artery and a small true aneurysm of the dorsalis pedis artery in the talus area. The changes were confirmed by a Computed Tomography Angiography test. At the same time, the immune and inflammatory origin of reported symptoms was excluded. After conservative treatment (rest, avoidance of cold temperatures, aspirin at a dose of 75 mg/day), relief of the symptoms was achieved during six-month medical supervision. During further observation, patient started again his physical activity (soccer, skiing). After 8 years of onset, he remains asymptomatic. He is observed as an out-patient.
