Traumatic injuries of the abdominal aorta.
Despite immediate operation, patients with abdominal aortic injuries and profound hypovolemic shock do not respond to the usual methods of resuscitation and die soon after celiotomy, prior to control and repair of the aortic injury. The rate of aortic hemorrhage exceeds the ability to restore blood volume. Shock becomes "irreversible." In such patients tamponade of the aortic injury may be effected by the use of an external counterpressure device such as a G-suit or MAST suit. These devices, used in conjunction with transthoracic aortic occlusion, may raise blood pressure sufficiently to perfuse the sritical coronary and cerebral circulation, allowing time to correct acidosis and locate, control, and repair the aortic injury. Early aggressive therapy should result in increased survival.
