Abstract
• The detection of underlying arterial injury is a major problem in the management of penetrating trauma. Arteriovenous fistula and false aneurysm are late sequelae of unrepaired injuries. The diagnostic accuracy of arteriography in clinically occult injury has not been defined. One hundred and seventy-seven patients with 183 penetrating extremity wounds underwent arteriography followed by operative vessel exploration. Arteriogram/operation correlation demonstrated 36 true-positive, 132 true-negative, 14 false-positive, and one false-negative arteriogram. Arteriography is sufficiently sensitive to exclude the presence of arterial injury in patients with equivocal clinical signs of injury. The radiographic changes are often subtle and diagnostic accuracy demands attention to the details of technique and interpretation. Unequivocal clinical signs of arterial injury and any arteriographic abnormality are indications for operative exploration. (Arch Surg 113:424-428, 1978)
