Traumatic Aortic Rupture Information

 A heparin-bonded artificial lung and centrifugal pump were used for three recent cases of multiple traumas.

Traumatic aortic rupture also called traumatic aortic disruption and transection. Traumatic aortic rupture (TAR) is a life-threatening injury. The injury is usually caused by high speed impacts such as those that occur in vehicle collisions and serious falls. It may be due to different rates of deceleration of the heart and the aorta, which is in a fixed position. By far the most common site for tearing in traumatic aortic rupture is the aortic isthmus, near where the left subclavian artery branches off from the aorta. It usually occurs in the region corresponding to the aortic isthmus (located between the left subclavian and the first intercostal arteries) as a result of shear forces generated by unrestrained frontal collisions or by side-impact crashes. The major risk of TAR is adventitial rupture which usually results in lethal hemorrhage.

Once traumatic aortic disruption is confirmed, the only treatment is surgery. Surgical therapy is often considered - though the timing and approach are controversial. However, morbidity and mortality rates for surgical repair of the aorta for this condition are among the highest of any cardiovascular surgery. The use of a heparin-bonded, artificial lung and centrifugal pump is advantageous because they make possible a reduction in the dosage of heparin in the cardiopulmonary bypass at the time of traumatic aortic disruption. Some can given pain medication, keeping the patient calm, and avoiding procedures that could cause gagging or vomiting.

Traumatic Aortic Rupture Treatment Tips

2. Some medication also relive pain.

3. Avoiding procedures that could cause gagging or vomiting.
