Penetrating combat-related thoracic trauma (review)

Objective — to study in detail the mechanisms and to investigate the imaging manifestations of combat-related penetrating thoracic injuries. Materials and methods. To perform the work, a literature search was provided according to the criterion «Thoracic penetrating combat-related trauma». 32 literary sources were selected for this request. Frag­ments of the clinical experience described in the literature according to the selected sources were illustrated by our own clinical cases of patients who were treated in Kharkiv medical institutions in 2022 for penetrating combat-related thoracic injuries. Results and discussion. Among victims who received chest injuries, polytrauma was most often diagnosed, complicated by several mechanisms of injury associated with penetrating, blunt, and explosive injuries. Pneumothorax and pulmonary contusion were the most common chest injuries. Thoracic injuries, thoracic vascular injuries, and lung ruptures were associated with the highest mortality rates, whereas pulmonary contusions, pneumothorax, and chest wall injuries were associated with relatively lower mortality rates. Chest X-ray is the first-line imaging method during the initial assessment of thoracic trauma in combat and non-combat situations. Such an examination is particularly important in polytrauma situations where multiple fatal injuries can be rapidly diagnosed in order to rapidly triage and include such an injury in the initial evaluation. Tension pneumothorax, large hemothorax, chest fragmentation, and some other lesions can be quickly diagnosed with a portable chest X-ray. Computed tomography (CT) of the chest is an important component of the comprehensive trauma evaluation, which allows to diagnose life-threatening injuries in hemodynamically stable patients with suspected multiple injuries not identified on chest X-ray. Chest CT detects 20 % more pathologies compared to chest X-ray. Conclusions. Combat-related thoracic trauma continues to be a significant contributor to the mortality rates of those injured in military operations. A clear injury pattern and atypical imaging manifestations of thoracic trauma are important to recognize at an early stage because of the acuteness of this category of patients and the impact of an accurate diagnosis on clinical management. Chest X-ray remains the main diagnostic tool. However, in modern and well-equipped institutions, chest CT, video-assisted thoracoscopy, and ultrasound scanning of the abdominal and chest cavity play an important role in the diagnosis of thoracic trauma. Quick and high-quality diagnosis and treatment are possible only in direct cooperation between surgeons and radiologists.
