[Post-traumatic subdural hygroma: diagnostic conditions and therapeutic attitude in Gabon].
An excessive collection of cerebrospinal fluid in the subdural space is known as subdural hygroma, or hydroma. By far, the most common cause is severe cranial trauma. The diagnosis can be made by angiography or computer tomography and, with certainly, only by trephine or burr hole evacuation. 11 cases of post-traumatic subdural hygromas, mainly diagnosed during operative interventions, from April 1981 to September 1988, are reported. Most patients had acute forms of hygroma requiring acute surgical intervention. The acuteness could broken down as: coma (medium Glasgow coma scale: 6), lateralizing neurologic signs (4 cases) and temporal lobe herniation signs (7 cases). There were difficulties in obtaining angiographic studies. 10 patients underwent burr hole evacuation. Craniectomy was performed in one case. Time between cranial trauma and surgical intervention varied from 24 hours (6 cases) to 34 days. It appears that the prognosis is related to the extent of primary brain damage and not to the pressure exerted by the (usually) small mass lesion. The authors propose a clinical management of this lesion and hope for improvement in the diagnostic technics available.
