[Potentials of a noninvasive method for studying volumetric cerebral blood flow in mitral stenosis and following its surgical correction].
The volumetric parameters of the cerebral blood flow were studied in 15 patients who had undergone comissurotomy, using the comprehensive rheographic method including tetrapolar rheoencephalography and transthoracic rheography. The non-invasive method makes it possible to determine the minute's volume of the brain circulation as well as its ratio to cardiac output. The results obtained point to a positive time-course of the brain blood flow following the surgical correction of mitral stenosis. The rheographic findings were verified by the results of computer-aided angioscintigraphy of the brain which showed the validity of the technique.
