[CLinico-morphologic correlations in cases of fatal outcome following removal of acoustic nerve neuromas].

The clinical findings were compared with the results of morphological examination of the brain in 32 patients who had died in different periods after surgery for removal of neurinoma of the acoustic nerve. In all cases vessels supplying the brain stem were injured during removal of the tumor. In 5 cases all three groups of arteries of the pons varolii were injured, which led to the development of infarction of half of the pons. The short circumflex pons arteries and the anterior inferior cerebellar artery were injured in 18 patients, which caused the formation of an infarct in the lateral part of pons varolii. The distal segment of the anterior inferior cerebellar artery was injured in 9 patients, as a result of which a small focus of infarction formed in the dorsolateral parts of the pons.
