[Transcapillary fluid filtration in the brains of patients after craniocerebral injuries].
The carotid artery and the jugular vein in patients with craniocerebral trauma were punctured simultaneously and the amount and direction of fluid filtration were calculated. The information made it possible to reveal in the posttraumatic period the predominant escape of fluid from the vascular channel into the cerebral tissue on the 1st-3rd days, a mild reverse flow of fluid on the 4th-7th days, and repeated escape of fluid from the vascular channel into the cerebral tissue on the 8th day; the duration of the last process was determined by the severity of the trauma. In patients who survived, this was followed by a period of intensive supply of fluid into the vascular channel coinciding in time with the clinical signs of an improvement in the patients' condition. In cases with a fatal outcome the flow of fluid through the vascular wall was directed into the cerebral tissue before death.
