[Substantiation of puncture perfusion of the subarachnoid space in experiments with biomanikins]

Experiments were performed in 30 biomannequins. Single puncture subarachnoidal perfusion cleared the subarachnoidal spaces of the brain and medulla free of preinjected dye. The clearance was more radical at the base, in the brain hemisphere cysterns and sulci, at the pons, medullar and spinal levels. This can be regarded as anatomical ground for the expedience of puncture perfusion in order to clear the subarachnoidal space.
