Among the numerous causes of carpal tunnel syndrome, thrombosed persistent median artery with bifid median nerve is extremely rare. Our presentation shows that an unusual case and surgical outcome of thrombosed persistent median artery with bifid median nerve causing acute carpal tunnel syndrome. Care has to be taken that identification of abnormal anatomy in the carpal tunnel is essential, especially in abruptly occurred carpal tunnel syndrome. We suggest that Doppler ultrasound examination is very useful in an outpatient clinic-based for identification of abnormal structure, which makes more quickly and accurate diagnosis than magnetic resonance image.
