PurposeCT is a valuable tool in assessing thoracic gunshot wounds. CT is also the method of choice in emergency, because it permits rapid depiction of bullet damage to the chest and to other body districts. This in turn permits correct assessment of the main thoracic injuries, plus adequate and prompt planning of surgical treatment or support intensive care. We report on the role of CT in diagnosing the complex pleuropulmonary, cardiovascular and thoracic wall injuries caused by gunshot wounds, with their specific and acute signs which differ greatly from those of other types of chest trauma.Material And MethodsIn the last 4 years, we observed 76 cases of gunshot injury, twenty-six of them involved the chest. The patients, 25 men and 1 woman (mean age: 32 years, range: 17-48), were all submitted to emergency CT with i.v. contrast agent injection and the CT-angiography technique. The reanimator was always present to monitor the patients' vital functions and shock state. CT of the chest was integrated with CT of the abdomen and pelvis in 4 cases and with CT of the skull in 3 cases, to detect associated bullet wounds if any.ResultsThe most frequent CT finding was lung parenchyma tear and bruise (25 cases), followed by hemothorax (18 cases) and subcutaneous chest wall emphysema (9 cases). Pneumothorax was seen in 5 cases, associated with hemothorax in 6; rib injuries were found in 7 cases; pneumomediastinum was found in 4 cases and areas of pulmonary atelectasis in 3; the diaphragm was ruptured in 4 cases. CT showed spinal involvement in 11 patients, with injury of D3 and D5 in 4 and 3 cases, respectively; signs of interrupted spinal marrow were found in 7 cases. Damage from gunshot wounds was detected in the liver, spleen, skull and limbs in 3, 2, 3 and 10 cases, respectively.Discussion And ConclusionsChest radiography shows major gunshot wound damage to the chest and lungs, except for heart injuries and minimal pneumothorax. When abdominal and skull injuries are associated, CT should be the method of choice because it permits prompt and panoramic assessment of the severity of pulmonary and extrathoracic damage. This results in prompt and targeted treatment, avoiding unnecessary delays which may damage the patient further.
