Abstract
We present 2 rare cases of patients with uncontrolled hemorrhagic shock induced by traumatic ascending aortic pseudoaneurysm rupture into the esophagus. Two men were presented to the hospital after traffic accidents. Their chest radiograph showed no obvious signs of aortic damage or aortic pseudoaneurysms but only a small amount of high-density shadow in the mediastinum and no specific clinical signs besides chest tightness or chest tenderness. The first case was misdiagnosed as pulmonary contusion and pleural effusion, and the second case was misdiagnosed as mediastinal lesions in the mediastina. They were given symptomatic and supportive treatment. Unfortunately, they died suddenly after >1 month of traumatic accident. At autopsy, ascending aortic pseudoaneurysms that broke into the esophagus and multiple organ hematocele were detected by gross examination. In histopathological examination, inflammatory cells and proliferated fibrous connective tissue were detected in the ascending aortic pseudoaneurysms, and the pathological gastrointestinal bleeding was not seen. The drugs and poisons were not found on toxicological analysis. The 2 patients died as a result of hemorrhagic shock from traumatic ascending aortic pseudoaneurysm rupture into the esophagus. We suggest that thoracic surgeon should be aware of the possibility of aortic injury after chest trauma to reduce misdiagnosis and prevent similar accidents.
