Management of injuries of the thoracic and abdominal aorta.
Thirty-five patients had surgery for injuries of the aorta at the Los Angeles County-USC Medical Center over a 4 1/2 year period. There were 27 survivors. The principles of management were to operate without delay if there was evidence of continued bleeding after initial fluid replacement as occurred in 11 patients. For the 24 patients who became stable after initial resuscitation, a more deliberate plan of management was used. Blood pressure was carefully monitored and controlled to avoid hypertension. Priorities for associated injuries were established and in several cases, they took treatment precedence over the aortic injury. Delay was sometimes necessary to utilize the more experienced personnel. In no instance did a stabilized patient hemorrhage during the delay. The most common injury seen was a blunt disruption of the proximal descending aorta. The details of the operative technique for this injury have been reported herein, along with a justification for not using either pump bypass or shunt to perfuse the distal aorta during the period of aortic cross-clamping.
