title: Brachial artery entrapment: compression by the supracondylar process.
abstract: Ischemia occurring during hyperextension of the upper limb in a 25-year-old woman led to the discovery of a supracondylar spur responsible for compression of the brachial artery with anomalous insertion of the pronator teres muscle. Resection of all abnormal structures provided immediate relief of symptoms. When atypical arterial symptoms of thoracic outlet syndrome occur in the upper limb, the brachial artery entrapment syndrome should be considered.
