[Rheoencephalographic examination of patients with stroke in Trendelenburg's position].

Typical rheoencephalographic investigations were done and repeated in Trendelenburg's position in 91 subjects including 40 healthy ones and 51 patients with ischaemic strokes. The test produced haemodynamic changes in the arterial and venous systems. The arterial changes manifested themselves as bilateral increase in blood flow, more pronounced on the side of the lesion, and bilateral increase in the vascular tonus more on the side contralateral to the focus. As a rule changes were observed in the shape of rheoencephalographic waves. Venous changes included mainly increased number of venous waves, more frequent in the patients, especially on the side contralateral to the lesion. The results of the observations are interpreted in confrontation with literature data.
