[Traumatic section of the thoracic aorta: its repair by direct aortic clamping].

Traumatic section of descendent aorta, severe complication of a thoracic traumatism, requires an early recognition and restoration because its high mortality rate. Between 1988 and 1990, three patients underwent surgical approach, by direct aortic clamping [correction of clamplaje], at our Service. In two cases, a heart stoppage appeared during the clamping/unclamping [correction of clampaje/desclampaje] maneuvers. One of them had previously electrocardiographic abnormalities, suggestive of heart contusion. Two patients died, one of them during surgical procedure because an irreversible heart stoppage, and the second patient died after 7 days because of a brain hemorrhage. One case presented postoperative paraplegia. Respective rates and literature about the main factors implicated in the diagnosis and treatment of such pathology are reviewed.

Direct surgery on the aorto-iliac area. Prostheses--endarterectomy?

Of the 365 surgical techniques performed on the aorto-iliac area in 354 patients, 448 extremities were revascularized by means of the insertion of a prosthesis as a by-pass, and 165 by thromboendarterectomy (TEA), either global or ilio-femoral. The patency rate at five years was 83% for prostheses, and 72% for TEAs, studied as a whole, or 75% for global TEAs, and 60% for ilio-femoral, once they had been individually analysed. The analysis of these results proves that the patency of the ravascularized aorto-iliac area depends more on the associated pathology in the femoro-popliteal distal area, than on the surgical technique that has been applied. There are no significant differences in relation to the early patency or mortality between the three groups, although as regards age, younger patients with fewer risk factors were selected for global TEA operations.
