Gunshot wounds to the upper extremity. Evaluation and management of vascular injuries.

Gunshot wounds to the upper extremity are uncommonly life threatening but are associated with a high incidence of significant long-term disability. The identification of vascular injuries is dependent on careful clinical examination and the liberal use of arteriography. Standard techniques of vascular repair should be followed for arterial reconstruction. The rate of successful vascular repair is in excess of 90%, but long-term function is limited by a high incidence of associated nerve injury.
