Extensive subcutaneous emphysema treated with subcutaneous angiocatheters.

Subcutaneous emphysema (SCE) seen in the emergency department is usually the result of traumatic chest injuries, surgical complications, or invasive airway procedures. SCE is usually a self-limiting phenomenon involving the chest wall and neck, though may progress to involve the deeper tissues leading to respiratory and cardiovascular compromise. Emergent intervention is indicated in such cases of extensive SCE, though the ideal approach to its management is not known.
