[The dynamics of brain edema in severe craniocerebral trauma (computed tomographic and magnetic resonance studies)].

The dynamics of vasogenic brain edema were studied with comparison of the results of CT and MRT in 17 patients with severe craniocerebral trauma (CCT). It was established that edema fluid clearance in vasogenic edema in the early stages of CCT occurs through various parts of the ventricular system, which is confirmed by the hypodensity "path" on the CT and the "path" of increased activity on the MRT. The authors revealed a phenomenon of "interruption" (cessation) of the sanogenous "path" connecting the foci of contusions and/or intracerebral hematoma with the ventricular system. The formation of a more or less marked mass-effect is evidently needed for the occurrence of pressure gradient which would be sufficient enough to move the edema fluid and disintegration products from the traumatic substrate into the ventricular system.
