[Complications of wide decompressive craniectomy. Clinical case].

A patient with acute subdural hematoma and multiple cerebral centres of infection, has been surgically treated with an hemicraniectomy. Three months after the operation, the appearance of both a counter-lateral stenic deficit and of a deterioration of the conditions of awareness, has been observed; these problems have been solved thanks to the operation of cranioplasty. The supposed mechanism appears to be that of the alteration of the pressory gradient existing between the environment and the cranial cavity.
