Investigation of tissue perfusion of the brain in patients with large and giant tumors of the bridge-cerebellar angle

Abstract

The article presents the results of the study of pons and cerebellar tissue perfusion in patients with large and giant cerebellopontine angle tumors. Perfusion computed tomography was performed in 10 patients with vestibular schwannomas and 8 patients with temporal bone meningiomas. The parameters of cerebral blood flow were calculated in 6 regions of interest in the area of the pons and the cerebellar hemispheres. There are manifestations of brain tissue hypoperfusion in the pons and hyperemia in the nearby parts of the cerebellar hemisphere. The revealed changes indicate the possibility of disorders of local cerebral blood flow after surgery.
