Tension hemothorax caused by a ruptured aneurysm of the descending thoracic aorta: report of a a case.

The rupture of an aneurysm of the descending thoracic aorta into the right thoracic cavity is a comparatively rare event, and it is very difficult to establish a diagnosis immediately and rescue such patients. We describe herein the successful surgical treatment of a patient with this life-threatening emergency by initiating immediate cardiopulmonary bypass. It is mandatory to drain the right thoracic bleeding through a left thoracotomy without delay to release the tension hemothorax. Furthermore, it is necessary to evacuate the right thoracic hematoma through a right thoracotomy because complete removal o f a hugh hematoma through a left thoracotomy cannot be effectively achieved.
