[Complete disruption of thoracic descending aorta without widening of the pseudoaneurysm].
A 41-year-old male was transported to our emergency room 25 minutes after blunt chest trauma. The chest X-ray film and CT scanning demonstrated left pulmonary atelectasis, hemothorax, and widening of mediastinum possibly due to hematoma. Hundred and fifty minutes after arrival to the hospital, we were rush to bring him to the operation theater suspecting serious injury of the thoracic organs in association with bleeding from left thoracic drainage tube without detection of the aortic rupture. The left standard thoracotomy disclosed no injury of the left lung, good continuity and no dilatation of the thoracic descending aorta. But visual blood flow observed through the adventitia of the aortic isthmus led us to the final diagnosis of the aortic rupture. After aortic clamping, the intima of the injured aorta was found to be completely disrupted for a length of 6 cm and was repaired with a vascular prosthesis under the partial cardiopulmonary bypass using a centrifugal pump. His postoperative course was uneventful. We reported a case of complete circumferential aortic rupture without widening of the pseudoaneurysm in the acute stage of the disease.
