title: Bilateral mini-open decompression in the treatment of carpal tunnel syndrome caused by persistent median artery: case report.
abstract: Carpal tunnel syndrome (CTS) is a common peripheral entrapment neuropathy that is caused by increased pressure within the carpal tunnel resulting in a chronic process of median nerve ischemia and segmental demyelination. We report on a patient with bilateral patent persistent median artery (PMA) affected by typical symptomatic CTS who was treated by bilateral mini-open decompression with complete improvement. For PMA-associated CTS, standard decompression is considered the treatment of choice, whereas resection should be reserved for pathological PMA. Mini-open decompression can be an alternative, as we have verified in this first description.
