[Tension pneumocephalus after surgical treatment of a bilateral chronic subdural hematoma: a banal and serious complication]. / Pneumocéphalie compressive après traitement chirurgical d'un hématome sous-dural chronique bilatéral: une complication banale et sérieuse.

The occurrence of postoperative pneumocephalus is a common event and is often trivial. When the intracranial air volume is significant, it creates intracranial hypertension causing tension pneumocephalus. This case report describes the occurrence of tension pneumocephalus after surgical drainage of bilateral chronic subdural hematoma. The pneumocephalus was responsible for severe postoperative neurological deterioration. The attending physicians should be aware of the possibility of occurrence of such complication. Treatment and prevention of pneumocephalus should also be well known by the medical staff.
