Double-lung point sign in traumatic pneumothorax

Over the last 10-15 years, treatment of tuberculosis patients with artificial pneumothorax has become widespread and there are many works devoted to collapse therapy in the press; details of the technique, efficiency of treatment, and complications are discussed. Spontaneous pneumothorax (SP) is one of the most dangerous complications of pneumothorax. Under p. p. we understand gas accumulation in pleural cavity in case of lung perforation, as the result of pathological process in the lung, more often of subpleural cavernous cavity breakthrough, caseous focus, or due to lung parenchyma needle trauma while applying pneumothorax.

Objectives: Traumatic pneumothorax is one of the causes of trauma mortality and morbidity. It is a problem for developing countries as many accidents can be avoided and there are few epidemiological data to support programs injury prevention. The main objective of the current study was to determine demographic characteristics, patterns, and severity of the injury, thoracic, and extra-thoracic related injuries in a Level 1 trauma center, Riyadh, Saudi Arabia (SA). Methods: This retrospective observational study used the King Abdulaziz Medical City Trauma Center’s trauma registry to review the data of traumatic pneumothorax patients admitted to the hospital from January 2001 to December 2018. Demographic characteristics, admission date and time, type and mechanism of injury, involved body area, and severity rates were analyzed. Results: A total of 708 patients of whom 92.3% were males. Blunt trauma (75.8%) is the most common cause of injury. Motor Vehicle Accidents (MVA) were the most common cause (57%) of traumatic pneumothorax. Rib fractures (36.5%), lung contusions (31.5%), and hemothorax (23.5%) were the most common clinical forms of chest injury associated with traumatic pneumothorax. On the other hand, the head injury (34.8%) was the most common extra thoracic part associated. The mean Injury Severity Score in the current study was found to be 20.1. Conclusion: This study showed the trends of traumatic pneumothorax injuries in a Level 1 trauma center, Riyadh, SA, showing MVA are the leading cause of traumatic pneumothorax in our region. These demographic data will be crucial for local health-care systems to be optimally resourced.

Background: Pneumothorax is one of the main complications of transbronchial lung cryobiopsy (TBLC). Chest ultrasound (CUS) is a radiation-free alternative method for pneumothorax detection. Objective: We tested CUS diagnostic accuracy for pneumothorax and assessed its role in the decision algorithm for pneumothorax management. Secondary objectives were to evaluate the post-procedure pneumothorax occurrence and risk factors. Methods: Eligible patients underwent TBLC, followed by chest X-ray (CXR) evaluation 2 h after the procedure, as our standard protocol. Bedside CUS was performed within 30 min and 2 h after TBLC. Pneumothorax by CUS was defined by the absence of lung sliding and comet-tail artefacts and confirmed with the stratosphere sign on M-mode. Pneumothorax size was determined through lung point projection on CUS and interpleural distance on CXR and properly managed according to clinical status. Results: Sixty-seven patients were included. Nineteen pneumothoraces were detected at 2 h after the procedure, of which 8 (42.1%) were already present at the first CUS evaluation. All CXR-detected pneumothoraces had a positive CUS detection. There were 3 discordant cases (κ = 0.88, 95% CI: 0.76–1.00, p < 0.001), which were detected by CUS but not by inspiration CXR. We calculated a specificity of 97.5% (95% CI: 86.8–99.9) and a sensitivity of 100% (95% CI: 87.2–100) for CUS. Pneumothorax rate was higher when biopsies were taken in 2 lobes and if histology had pleural representation. Final diagnosis was achieved in 79.1% of patients, with the most frequent diagnosis being hypersensitivity pneumonitis. Regarding patients with large-volume pneumothorax needing drainage, the rate of detection was similar between CUS and CRX. Conclusion: CUS can replace CXR in detecting the presence of pneumothorax after TBLC, and the lung point site can reliably indicate its size. This useful method optimizes time spent at the bronchology unit and allows immediate response in symptomatic patients, helping to choose optimal treatment strategies, while preventing ionizing radiation exposure.
