다발성 손상 환자에서 Abdominal CT Scan을 이용한 흉부손상의 진단 = DIAGNOSIS OF CHEST INJURY BY ABDOMINAL CT SCAN IN MULTIPLE INJURED PATIENTS

다국어 초록 (Multilingual Abstract)

Injuries to the thorax was evaluated among 224 patients admitted to the emergency room with multiple trauma who had undergone abdominal CT scan for possible intraabdominal injuries. In order to detect possible intrathoracic injury, abdominal CT scan were sliced 1cm apart starting from a point 2cm superior to the diaphragm. Soft tissue and lung window were performed on cross sectional images 2cm, 1cm above the diaphragm and to the diaphragm level. Among the 224 patients with multiple trauma who had undergone abdominal CT scan, thoracic injuries previously undetected on plain chest X-ray were detected in 42 patients(18.8%) on the abdominal CT scan. 123 different thoracic lesions were found to present on the 42 patients diagnosed to have thoracic injuries on the abdominal CT scan, among which there were 67 cases of hemothorax, 24 cases of lung contusion, 24 SQ emphysematous lesions, 6 cases of pneumothorax, and chest wall hematoma in 1 patient. Among the 67 patients with hemothorax 21 patient(31.3%) and 4 patients(66.7%) among the 6 with pneumothorax eventually received closed thoracostomy, and 4 patients among the 24 with lung contusion received ventilator care following admission. In conclusion, when abdominal CT scan is performed for evaluation of suspected abdominal injuries with absence of thoracic injuries on plain chest X-ray, possible thoracic as well as abdominal lesions should be closely observed.
