A ruptura traumática da aorta torácica é uma situação que expõe o paciente a risco de vida e que pode ser causada por vários mecanismos, principalmente por lesões penetrantes ou iatrogênicas e traumas contusos. Embora os mecanismos penetrantes predominem, o número de pacientes com rotura da aorta devido a trauma contuso tem aumentado. Este artigo apresenta um panorama, enfocando patogênese, diagnóstico, urgência e tipo de tratamento referentes a lesões traumáticas da aorta torácica; o artigo contém, além disso, um relato de experiências de um centro que trata essas lesões. A maior dificuldade na avaliação de dados sobre lesão contusa da aorta é que as revisões retrospectivas freqüentemente classificam em um mesmo grupo os pacientes com todos os tipos de lesões da aorta, comparando resultados de lesões em diferentes localizações, com diferentes métodos de reparo e diferentes cirurgiões e/ou instituições.
Traumatic rupture of the thoracic aorta is a life threatening situation, and may be secondary to several mechanisms; mainly penetrating or iatrogenic lesions and blunt trauma. Although penetrating mechanisms predominate, the number of patients with aortic disruption due to blunt trauma has continued to increase. This paper shows an overview focusing on the pathogenesis, diagnosis, timing and type of treatment regarding traumatic injuries of the thoracic aorta; it also reports the experience of one single center that deals with these lesions. The major difficulty in the evaluation data on blunt aortic injury is that retrospective reviews often group together patients with all types of aortic lesions, comparing outcomes for injuries in different locations, with diverse methods of repair and different surgeons and/or institutions.

Abstract
Traumatic rupture of the thoracic aorta is a life threatening situation, and may be secondary to several mechanisms; mainly penetrating or iatrogenic lesions and blunt trauma. Although penetrating mechanisms predominate, the number of patients with aortic disruption due to blunt trauma has continued to increase. This paper shows an overview focusing on the pathogenesis, diagnosis, timing and type of treatment regarding traumatic injuries of the thoracic aorta; it also reports the experience of one single center that deals with these lesions. The major difficulty in the evaluation data on blunt aortic injury is that retrospective reviews often group together patients with all types of aortic lesions, comparing outcomes for injuries in different locations, with diverse methods of repair and different surgeons and/or institutions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
