Air under pressure: a case report on tension pneumomediastinum arising from traumatic injury

Abstract

Abstract Background Tension pneumomediastinum (TPM) is a rare but critical condition characterized by the accumulation of air in the mediastinum, leading to increased intrathoracic pressure and cardiovascular compromise. This case report is novel due to the rarity of TPM arising from blunt chest trauma and the necessity for emergent surgical intervention after initial conservative management failed. Case presentation A 63-year-old male presented with severe chest pain and dyspnea following a high-impact motor vehicle collision. Initial assessment revealed tachypnea, tachycardia, and hypotension, along with extensive subcutaneous emphysema over the chest and neck. Imaging confirmed pneumomediastinum and bilateral pneumothoraxes, consistent with TPM. Despite initial management with high-flow oxygen and bilateral chest tube insertion, the patient’s condition deteriorated, necessitating emergent mediastinal decompression via an anterior subxiphoid incision. This intervention resulted in immediate hemodynamic improvement. Conclusions This case underscores the importance of recognizing TPM in patients with chest trauma and highlights the need for prompt surgical intervention in cases of hemodynamic instability. Early and accurate diagnosis and timely surgical management are crucial for improving patient outcomes in TPM.
