[The arterial bed of the spinal cord in newborn infants following segmental artery ligation].
The aim of the investigation was to find out the number of ligated segmental arteries which did not cause neurological spinal complications. The segmental arteries were ligated at different distances from the aorta and in different numbers. A unilateral ligation of 1--8 segmental arteries near their branching from the aorta did not result in alterations of the arterial bed of the spinal cord. A bilateral symmetrical ligation of 4--5 segmental arteries next to aorta caused a poor filling of root vessels. Uni- and bilateral ligations of 3--4 intercostal and lumbar arteries near the aorta and at the level of intervertebral foramens resulted in both root arteries and the anterior spinal artery being not filled with an opaque substance.
