Brachial artery entrapment syndrome. Intermittent arterial compression as a result of muscular hypertrophy.

A description is given of an entrapment syndrome of the brachial artery in a thirty-nine-year-old muscular man. The diagnosis was made with the help of angiography. The intermittent compression was not caused by a congenital anomaly, but exclusively by muscular hypertrophy. By cutting the lacertus fibrosus the complaints and symptoms completely disappeared. No previous record of this clinical picture can be found in the world literature, but it can be assumed that this is not an isolated observation.
