This compression could be associated to several causes, e.g., a sequela resulting from vein cauterization (Lake, 1974); fibrous arcs formed by the superficial flexor muscle of the fingers, teres pronator, or both; compression caused by the Gantzer muscle, accessory head of the long flexor muscle of thumb (Collins & Weber, 1983; Dellon & Mackinnon; Olenick et al., Shirali et al., 1998); anatomical variations and vascular chains surrounding the nerve, as related by Braun & Spinner, 1991, they noticed during a surgical intervention, that the compression of the nerve occurred in the distal part of the arm, caused by communicating veins that jointed to the cephalic and basilic veins and with the brachial vein through a bicipital aponeurosis.
