[Complication of a successful cardiopulmonary resuscitation].

A case of bilateral extensive subcutaneous emphysema secondary to external cardiac massage is reported. This is a rare complication. It occurs with a pneumothorax after resuscitation maneuvers. The diagnosis is based on a bundle of anamnestic, clinical and radiological arguments. This case demonstrates the importance of performing a simple prehospital thoracostomy on the finger without chest tube placement and demonstrates the need for systematic investigation of possible complications in any patient who has undergone external cardiac massage.
