Traumatic Aortic Rupture

Aortic transection or other forms of traumatic aortic injury usually occur from a deceleration type of blunt trauma and usually occurs when a patient smashes his chest against the steering wheel in a motor vehicle accident. The tear usually occurs at the region of the ligamentum arteriosum just distal to the left subclavian artery. In this case, a left thoracotomy is performed and if there is a small hematoma without proximal extension, one can clamp the aorta proximal to the left subclavian, separately clamp the left subclavian, clamp the distal aorta and then do the repair with interposition graft if the cross-clamp time can be kept to less than 30 minutes. Cross-clamp time greater than 30 minutes results in an increased chance of paraplegia. If there is a large hematoma with proximal extension into the transverse or ascending aorta, femoral-femoral bypass is established, the patient is cooled, circulatory arrest established, the aorta opened and the repair done. This is achieved via a left thoracotomy. For ascending aortic traumatic injuries, a median sternotomy is performed and right atrial-femoral bypass is established. If one can get a cross-clamp proximal to the innominate, then one can perform the procedure with the aortic cannula in the distal ascending aorta or in the transverse arch. If one cannot get a cross-clamp on proximal to the innominate, then right atrial-femoral artery bypass is established, the patient cooled and hypothermic circulatory arrest established to perform the repair. Aortic transection is fur-
