Usefulness of routine computed tomography in the evaluation of penetrating war injuries to the chest.

OBJECTIVES This review was conducted to compare the contributions of chest X-ray (CXR) and computed tomography (CT) towards detecting intrathoracic damage in patients with penetrating war injuries to the chest and to determine whether identification of additional injuries by chest CT will have an impact on the choice of therapeutic interventions and clinical outcomes. METHODS We reviewed records of 449 patients (374 men, mean age 29.3 ± 14.8 years) who were admitted to our hospital with penetrating war injuries to the chest over a 7-year period. Collected data included mechanisms of injury, associated injuries, results of CXRs and chest CTs, methods of management, in-hospital stays, complications and mortalities. RESULTS Immediate screening CXRs were obtained in all patients not requiring emergent thoracotomies, of which 91.4% showed positive signs of injury. Chest CTs were performed at the discretion of the physicians in 49.4% of patients, and CXR-positive findings were confirmed in all cases, while revealing additional injuries in 11% of patients. Chest CT findings led to additional closed chest drainage in 5.6% of patients but had no impact on treatment strategy in 94.4% of scanned patients. Follow-up CXRs showed new positive findings in 22 patients, leading to additional closed chest drainage in 3 patients and delayed open thoracotomies in 7 other patients. CONCLUSIONS CXRs continue as the primary diagnostic modality in the assessment of patients with penetrating war injuries to the chest. Chest CTs can be omitted in most patients, thus reducing CT imaging case-load substantially, while most clinically significant chest injuries remain sufficiently recognized.
