Using the canine thalamic infarction model, hemodynamics, CO2 responses and
thalamic EEG changes were studied in 7 dogs. Of the 7 animals, 4 showed
hemorrhagic infarction and 3 did not, following recirculation after 6 hours
of vascular occlusion. 1) The rCBF threshold for producing hemorrhagic
infarction when recirculation following 6 hours of vascular occlusion was
approximately 50% of the pre-occlusion level. 2) rCBF of the animals
showing hemorrhagic infarction included hyperperfusion due to
recirculation, and then fell to a level below the pre-occlusion level in a
relatively short period. The CO2 response became disturbed both during
occlusion and after release of occlusion. Thalamic EEG was nearly flat
during vascular occlusion and recovery was not seen following
recirculation. 3) rCBF of the animals not showing hemorrhagic infarction
recovered rapidly to the pre-occlusion level due to recirculation. The CO2
response was somewhat disturbed during occlusion, but recovered following
recirculation. Thalamic EEG was well preserved both during occlusion and
after release.
