During 1982, 312 patients with 408 vascular injuries and 48 cardiac injuries were seen. Two or more vascular or cardiac injuries were present in 34% of patients. Over 87% of injuries were secondary to gunshot wounds, stab wounds, or shotgun wounds. Vascular injuries were most commonly seen in the extremities (39.9%) or abdomen (31.9%). The most common arterial injuries occurred in the brachial artery (39 patients), while the most common venous injuries occurred in the internal jugular vein (26 patients). Arterial injuries were treated by the insertion of substitute vascular conduits (33.9%), ligation (22.6%), lateral arteriorrhaphy (18.6%), or end-to-end anastomosis (15.4%). Venous injuries were treated by lateral venorrhaphy (63.7%) or ligation (25.1%). In the 272 patients admitted with only vascular injuries, survival was 84.2%. Cardiac injuries in 38 patients most commonly occurred in the right ventricle (50%) and right atrium (25%). In the 34 patients who had only cardiac injuries and less than 4 minutes of prehospital cardiopulmonary arrest prior to arrival in the emergency center, survival was 64.7%.
