No período de julho de 1986 a dezembro de 1995, foram operados 12 pacientes com rotura traumática da aorta torácica. Nove pacientes apresentavam rotura aguda da aorta e 3 rotura crônica. Em todos os pacientes a lesão localizava-se logo abaixo da emergência da artéria subclávia esquerda (istmo). Onze pacientes foram operados sob pinçamento aortico simples e em apenas 1 associamos shunt não heparinizado entre a artéria subclávia esquerda e a aorta descendente. O tempo médio de pinçamento aórtico foi de 33,2 minutos. Onze pacientes sobreviveram. Um paciente faleceu no pós-operatório imediato, devido a sangramento, e outro apresentou paresia de membros inferiores. Dez pacientes evoluíram sem complicações no pós-operatório. Concluímos que a correção da rotura traumática da aorta torácica, sob pinçamento aórtico simples, é técnica aceitável no tratamento cirúrgico desta lesão.
From July 1986 to December 1995 twelve patients with traumatic rupture of the thoracic aorta were operated on. Nine patients had an acute injury and three had chronic injury. In all patients the lesion was located in the isthmus. Eleven patients were operated on with simple cross-clamp and in just one patient a shunt without heparin, between the left subclavian artery and thoracic aorta, was done. Medium aortic occlusion time was 33.2 minutes. Eleven patients are alive. There was one hospital death (8.3%) due to bleeding. One patient developed paresis of the lower limbs. Ten patients survived without complications. In our opinion the simple cross clamp technique is acceptable in the surgical repair of the traumatic rupture of the thoracic aorta
