Trauma-related pneumopericardium (TRPP) is the collection of air in the pericardial space secondary to trauma, potentially leading to tension pneumopericardium (TPP) in which the entrapment of air generates sufficient pressure to compromise cardiac output leading to a life-threatening cardiac tamponade and circulatory failure. We aim to classify the diagnostic and therapeutic approaches of TRPP and the causes of the subsequent development of TPP. A computer-based search of all published reports on TRPP in the medical literature from database inception to March 2020, on MEDLINE, Ovid, and Scopus; analyzing the data regarding initial status at presentation, extent of injuries, diagnostic and treatment measures with the intention to have an understanding of the clinical behavior and management outcomes of TRPP. The search identified 84 published case reports of 105 patients with TRPP. In conclusion, TRPP leading to TPP is described in the literature as a condition that involves a young male who is subjected to blunt trauma, most commonly in a motor vehicle collision, presenting as a polytrauma patient in a state of shock and low systolic blood pressure, or possibly in cardiac arrest. In addition, he might have a tracheobronchial injury with or without pneumothorax or pneumomediastinum and might require mechanical ventilation.

opment of psoas muscle abscess following such an injury is extremely rare. Moreover, literature surrounding psoas muscle hematoma formation as a consequence of penetrating abdominal injury is scarce. Objective: We report a case of psoas abscess formation following the development of psoas hematoma in a patient who suffered from a penetrating abdominal injury. Case presentation: A 40-year-old Indian male presented to the Emergency department with multiple abdominal cut and stab wounds as a result of physical assault. A computed tomography scan revealed injuries to the ascending colon along with hemoperitoneum and right psoas muscle hematoma. Exploratory laparotomy was performed in which a right hemicolectomy and a right psoas muscle evacuation were successfully achieved along with multiple drainage tubes placed. Six days later, a peritoneal fluid culture tested positive, and a computed tomography scan revealed right psoas muscle collection which was diagnosed as an abscess. Treatment of the abscess included antibiotics and ultrasound-guided drainage. Patient was eventually discharged but was lost to follow-up. Conclusion: The development of iliopsoas abscess and hematoma as a consequence of abdominal penetrating injuries is a rare occurrence. Diagnosis can be made by computed tomography imaging and examination of the drained fluid. Managing a case with both of these rare phenomena can be challenging due to the scarce literature highlighting and comparing the different management modalities.

Background: Motor vehicle collisions (MVC) are a major burden on healthcare systems. Saudi Arabia is one of the countries with a high mortality rate of MVC. Blunt tracheobronchial injuries are rare; however, it is a catastrophic event that requires a high center of care. Lack of experience and advanced faculty prompt early stabilization and transfer of the victim for advanced care. Due to the uncertainty of management of these injuries, we would like to share our experience in dealing with such injuries. Objective: To address the difficulties in initial management and transfer of patient with blunt traumatic tracheobronchial injuries. Methods: This is a single-center retrospective case-series study including patients admitted as cases of trauma including all age groups with blunt acute tracheobronchial injuries confirmed by imaging or bronchoscope. Results: In our study, four patients with tracheobronchial injuries were identified, and a retrospective analysis was performed. Two of the males and one of the females are adults, while the other two are pediatrics. Two of them have a right main bronchial injury and the other two have a left main bronchial injury. Posterolateral thoracotomy and bronchial anastomosis were performed on all four patients and were followed up. Conclusion: In Saudi Arabia, blunt trauma is a prevalent type of injury, although tracheobronchial injuries are uncommon. In the event of trauma, a high index of suspicion of tracheobronchial injuries in a high mechanism injury warrants prompt treatment. Due to a lack of experienced and specialized hands in this field, management may be delayed, and eventually lead to unfavorable outcomes, hence we thought of a guide to facilitate the decision-making.
