[Pathogenesis of traumatic subdural hydroma]. / O patogeneze travmaticheskikh subdural'nykh gidrom.

ABSTRACT

Pathogenetic factors leading to the formation of traumatic subdural hygromas (TSH) are identified from analysis of the results of complex examination of 156 patients. Comparative biochemical tests of CSF, blood serum and the hygroma fluid in 15 patients showed the hygroma to contain CSF. The formation of TSH was always a consequence of brain contusion, usually of a severe degree, and rupture of the basal CSF cisterns. As the result of critical analysis of the existing theories of TSH pathogenesis a new conception is formulated.
