title: [Carpal tunnel syndrome from a thrombosed median artery--four case reports and review of the literature].
abstract: The aetiology of the carpal tunnel syndrome is unknown in most cases. Among our patients we found four with acute thrombosis occurring in a persistent median artery which led to acute carpal tunnel symptoms. The purpose of this study was to compare our cases with those from the literature and to show possible causes for the thrombosis. In conclusion, thrombosis of a persistent median artery as a cause of acute carpal tunnel syndrome is certainly very rare. Sudden onset of pain, local tenderness at the palm and decreased sensation in the median nerve distribution may provide clues for the diagnosis. Prior to surgery ultrasound can be performed to confirm the diagnosis.
