[Surgical treatment of aortic rupture by blunt chest trauma].
During a ten-year period, seven patients with traumatic rupture of the thoracic aorta were operated upon. Four patients of them were operated within one week. Chest X-rays and chest computed tomography could not always reveal the exact diagnosis of aortic rupture. Intravenous digital subtraction angiography was useful to confirm the diagnosis. The repair of the rupture was accomplished with the adjunct of left heart bypass using Bio-pump, which was useful to reduce the bloodloss with a limited systemic heparinization. Another three patients were diagnosed to have chronic post-traumatic aneurysm of the thoracic aorta and underwent aortic replacement with prosthetic graft. One of seven patients died at seventh postoperative day because of cerebral contusion, the associated lesion of an automobile accident. It is stated that the aortic rupture is immediately fatal in approximately 80% of individuals, and most of remaining 20% die within 2 weeks unless the lesion is repaired. Therefore immediate operative intervention is recommended when the aortic rupture is strongly suspected. Chronic post-traumatic aneurysms should be resected because it has become apparent that the majority of patients with this lesion will develop complication, such as sudden rupture.
