Peripheral vascular trauma from close-range shotgun injuries.

This report summarizes an eight-year experience (1976 to 1983) with 49 close-range shotgun blasts with associated major vascular injuries seen in a large urban hospital. Injuries to the upper extremity (40%), lower extremity (56%), and neck (4%) were seen. A high frequency of associated deep venous injury (82%), nerve injury (37%), fracture (33%), massive soft-tissue loss (43%), and compartmental hypertension (39%) was observed. There were no deaths in this series, and the limb salvage rate was 96%. Neither patient with multiple carotid artery injuries suffered a neurologic deficit. We attribute our success in the management of these complex injuries to rapid fracture immobilization, early and aggressive use of fasciotomy, adequate débridement of devitalized tissue, repair of deep venous injuries, arterial repair with autogenous tissue, and extra-anatomic bypass grafting in selected cases.
