Cerebral blood flow and clinical outcome in patients with thalamic hemorrhages: a comparison with putaminal hemorrhages

Abstract

It has been reported that the reduction of cerebral blood flow (CBF) is more pronounced with thalamic hemorrhages than with putaminal hemorrhages, and the clinical outcome is worse with the former. However, the mechanism underlying these differences is not clear. We compared neurologic status, hematoma volumes, outcome scores. and early (< 1 month) and late (2-12 month) CBF values between 15 patients with thalamic hemorrhages and 28 patients with putaminal hemorrhages. We also correlated thalamic versus hemispheric CBF on each side and ipsilateral versus contralateral thalamic and hemispheric CBF. Finally, we evaluated the response to acetazolamide during the late stage. Thalamic hemorrhages were associated with a more pronounced reduction in CBF bilaterally, even though their hematoma volumes were much smaller. Contralateral to the hemorrhage, the discrepancy in CBF values between the two groups became greater in the late stage because CBF started to recover in putaminal hemorrhages but persistently deteriorated in thalamic hemorrhages. In the group with thalamic hemorrhages, the correlation between thalamic and hemispheric CBF ipsilateral to the hemorrhage and between thalamic CBF on both sides was disrupted in the early stag...Continue Reading

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
