Subcutaneous Emphysema Top Journals

 Subcutaneous emphysema  may result from puncture of parts of the respiratory or gastrointestinal systems. Particularly within the chest and neck, air may become trapped as a results of penetrating injury (e.g., gunshot wounds or stab wounds) or injury . Infection (e.g., gas gangrene) can cause gas to be trapped within the subcutaneous tissues.  Subcutaneous emphysema are often caused by medical procedures and medical conditions that cause the pressure within the alveoli of the lung to be above that within the tissues outside of them. Its commonest causes are pneumothorax and a chest tube that has become occluded by a grume or fibrinous material. It also can occur spontaneously thanks to rupture of the alveoli with dramatic presentation. When the condition is caused by surgery it's called surgical emphysema. The term spontaneous subcutaneous emphysema is employed when the cause isn't clear. Subcutaneous emphysema  isn't typically dangerous in and of itself, however it are often a symbol of very dangerous underlying conditions, like pneumothorax.  Since the air generally comes from the thoracic cavity , subcutaneous emphysema usually occurs on the chest, neck and face, where it's ready to travel from the thoracic cavity along the fascia
