Surgical treatment of aneurysms of the thoracic aorta. Presentation of personal cases

Six cases of aneurysm of the thoracic aorta, four located in the 1st segment and two in the 3rd, are reported. The four cases in the ascending aorta presented a different aetiology: a) aneurysm on aortic stenosis (case 1); b) atheromatous aneurysm (case 2); c) aortic dissection (case 5); d) aneurysm due to dystrophy of the media in a patient with Marfan's disease (case 6). 3 tubular prosthetic substitutions of the ascending aorta were made (with a valvular substitution and commissural relocation associated with right aorto-coronary venous by-pass) and one plastic intervention on the aorta with valvular substitution. The aneurysms of the descending thoracic aorta presented traumatic aetiology and were treated with resection-dacron graft, using femoral artero-venous partial CEC.
