We report the case of a 23-year-old man who suffered a service accident by crushing the thorax between two tanks during army maneuvers that resulted in an adventitial rupture of the ascending thoracic aorta extending to the Crosse. Treatment consisted of replacement of the ascending aorta with a 24 mm Hemashield straight tube and re-implantation of supra-aortic vessels at the dome of the prosthesis.展开更多
