[Epileptic seizures in stenosis and de-stenosis of the common carotid arteries].

Experiments were performed in 64 white laboratory rats sensitive to acoustic stimula with disturbances and a restitution of cerebral circulation due to stenosis and destenosis of the common carotid arteries. The epileptic reaction of rats was studied prior to and following stenosis and destanosis by means of audiogenic epilepsy. In highly sensitive rats of the KM strain with a leftside stenosis of the common carotid arteries the epileptical reaction did not change significantly. In rats, selected from a random population after a simultaneous bilateral stenosis of the common carotid arteries there was an intensification of epileptical seizures in 70,6%. The restitution of the blood flow after 10 days following stenosis of the common carotid arteries facilitated a drop of the convulsive reaction. In animals who were not operated for the restitution of the blood flow in the common carotid arteries the reaction remained high even after 3 months following disturbances of cerebral circulation.
