title: [Transcranial duplex scanning in estimation of cerebral hemodynamics in patients with secondary cochleovestibular neuritis].
abstract: The authors present pilot experience with transcranial duplex scanning (TCDS) of the cerebral vessels in 17 patients with secondary cochleovestibular neuritis combined with chronic leptomeningitis (primarily of the posterior cranial fossa). This method has determined extra- and intracranial hemodynamics, characterized arterial and venous blood flow qualitatively and quantitatively, outlined possible genetically determined factors in development of dyscirculatory disorders. Finally, hemodynamic defects of two types were revealed in 12 patients. Type 1 (3 patients) was characterized by asymmetric circulation in the territory of the middle, anterior and posterior cerebral arteries, by the absence of venous congestion. Type 2 (9 patients) was characterized by impaired venous outflow manifesting as higher speed of the blood flow and its phase response along the intracranial veins and sinuses. In 7 patients these defects combined with asymmetric circulation along brain stem arteries. These patients were diagnosed to have perilymphatic labyrinthine hydrops.
