Central vessel trauma.
During a 24 month period, 30 patients were treated for central vessel trauma (CVT). Injured vessels included all of the major arteries and veins in the chesk, neck and abdomen except the infrarenal aorta. Overall survival was 70 per cent. Experience with specific injuries is reviewed with commentary on surgical access to difficult areas including the thoracic outlet, suprarenal aorta and inferior vena cava. Common factors in the nine deaths are reviewed with the findings that cardiac arrest at any time during pre- or intraoperative management is uniformly lethal; emergency thoracotomy for control of bleeding carries an expectedly high mortality; cross-clamping of the descending thoracic aorta to control hemoperitoneum has a limit of tolerance of about one hour, and prolonged shock, whether compensated or profound is poorly tolerated and is associated with a high mortality.
