The topographic anatomical basis for ventriculosinusal shunting in hydrocephalus in nursing and young infants

: The peculiarities in the structure and topographic anatomical relations of the superior longitudinal, lateral, and sigmoid sinuses were studied on block preparations of the posterior cranial fossa of 14 children under 3 years of age who died from somatic diseases. It was shown that intrasinus inclusions preventing catheterization of the sinus (bands and septa) were absent at the junction of the first angle of the sigmoid sinus with its descending part. The authors recommend this area for shunting operation--ventriculosinusotomy--in progressive hydrocephalus.
