Surgical Excision of a Thrombosed Persistent Median Artery in a Professional Hockey Player.

A persistent median artery is a rare anatomical variant found in approximately 10% of the population. Carpal tunnel syndrome due to a thrombosed persistent median artery is exceptionally rare. A 29-year-old professional hockey player presented with a 2 months history of hand pain and intermittent paresthesias without vascular symptoms. Magnetic resonance imaging and angiography demonstrated a 2-cm thrombosis in a persistent median artery at the level of the carpal tunnel, with otherwise normal vascular anatomy. He was treated with surgical excision of the thrombus and carpal tunnel decompression. The patient's symptoms resolved rapidly and he was able to return to sport without restrictions. Incidental imaging performed several months after surgery demonstrated a normal vascular pattern in the treated hand.
