Traumatic rupture of the false lumen in a patient with preexisting chronic dissection of the descending thoracic aorta.

Abstract

A 63-year-old man was transported to the emergency medical center due to blunt chest trauma combined with a fractured left leg caused by a motorcycle accident. He complained of severe dyspnea. Contrast-enhanced computed tomography revealed chronic aortic dissection DeBakey III, mediastinal hematoma of high density just above the diaphragm around the aorta, and an intimal flap-like shadow in the false lumen. Traumatic aortic rupture (TAR) with chronic aortic dissection was suspected. Aortography showed no clear sign of leakage, but a double-contour density was found in the outer wall of the false lumen of the descending aorta just above the diaphragm. He was therefore diagnosed with TAR and underwent an emergency operation. At the operation, rupture in the outer wall of the preexisting false lumen was found and was directly sutured. Acute renal failure developed immediately after surgery, which improved after several hemodialyses. We consider our case rare because no report has been so far made on TAR with chronic dissection.
