Case:
A 51-year-old man presented with pain and paresthesias in the median nerve distribution and a subjective loss of grip strength. Imaging revealed a thrombosed persistent median artery in the carpal tunnel abutting the median nerve. The thrombosed portion of the artery was surgically excised, and the patient experienced resolution of symptoms.
Conclusion:
Persistent median artery thrombosis is rare and can cause carpal tunnel syndrome. Ultrasound is a useful tool for diagnosis and appropriate surgical planning. Although treatment with systemic anticoagulation is an option, surgical excision resulted in resolution of symptoms and an excellent short-term outcome.
