RESUMO

O trauma representa, no mundo actual, uma das principais causas de morte, e o acometimento torácico significa um importante agravamento nas vítimas de trauma multi-sistémico. Neste trabalho foram estudados os aspectos tomográficos de 200 pacientes com trauma torácico. As lesões pulmonares predominaram, tendo sido observadas em 192 casos (96%), manifestadas sob a forma de contusões em 178 casos (89%), atelectasias em 41 casos (20,5%), lacerações em 15 casos (7,5%) e hematomas em 6 casos (3%). Lesões pleurais foram demonstradas em 140 casos (70%), dos quais em 121 casos (60,5%) havia hemotórax e em 84 casos (42%) pneumotórax. As lesões mediastínicas estiveram presentes em 28 casos (14%), com pneumomediastino em 18 (9%), hematoma mediastínico em 7 casos (3,5%), hemopericárdio em 4 (2%) e lesões da aorta em 3 (1,5%). As lesões diafragmáticas foram observadas em 8 pacientes (4%). O enfisema de partes moles foi demonstrado em 36 casos (18%).

ABSTRACT

Trauma is nowadays one of the most common causes of death and traumatic thoracic lesions are important agravant to trauma patients. In this work the aspects of computed tomography from 200 cases of thoracic trauma were studied. Lung lesions predominated, found in 192 cases (96%), manifested as contusions in 178 cases (89%), atelectasis in 41 cases (20,5%), lacerations in 15 cases (7,5%) and hematomas in 6 cases (3%). Pleural lesions were showed in 140 cases (70%), among them in 121 cases (60,5%) there were hemothorax and in 84 cases (42%), pneumothorax. Mediastinal lesions were observed in 28 cases (14%), with pneumomediastinum in 18 cases (9%), mediastinal hematoma in 7 cases (3,5%), hemopericardium in 4 cases (2%) and aortic lesions in 3 cases (1,5%). Diaphragmatic rupture was seen in 8 pacients (4%). Soft tissue emphysema was demonstrated in 36 cases (18%).
