[Sequelae of diathermocoagulation of cerebellar arteries and veins in normal rabbits and rabbits sensitized to brain antigen].
Electrocauterization of an artery or a vein on the surface of the posterior lobe of the cerebellum may cause no focal changes in the bed of the occluded vessel, or result in varying severity and extension of lesion of the posterior cerebellar lobe. In occluding an artery a focus of complete necrosis or oedema is formed in its bed, while in occluding avein a focus of oedema is formed that may be accompanied by erythrocytic extravasation. In the group of animals sensitized with brain antigens a tendency towards oedema enhancement, and a vascular permeability increase is noted, neuronal changes are more frequent at a distance from the occluded vessel's basin. However, the importance of sensitization is, as a rule, masked by individual peculiarities of the collateral supply or venous return in the bed of the occluded vessel.
