[Experimental study of the microcirculatory bed of the brain. (II. Circulatory disorders after craniocerebral injuries)].

Dosed moderately severe craniocerebral injury was inflicted upon puppies and rabbits. After different periods (from 17 minutes to 3 days) perfusion with India ink was conducted under anesthesia and the no-reflow phenomenon was studied. All vessels in the experimental animals remained patent in the early (up to 2 days) period after the injury. Vasospasm with zones of obstruction of the microcirculatory bed was more or less pronounced in different areas of the brain 3 days after the injury. Microcirculation is maintained in the hypothalamus after craniocerebral injury even in the presence of gross microcirculatory disorders in the other areas of the brain, the thalamus among others.
