OBJECTIVES: Crossed cerebellar diaschisis (CCD) is a secondary phenomenon caused by supratentorial brain injury, characterized by hypoperfusion and hypometabolism of the contralateral cerebellum. This study aimed to investigate the correlation between the quantitative data of initial supratentorial ischemia and CCD, and to further explore the prognosis value of CCD in the hyperacute phase.
MATERIALS AND METHODS: The imaging and clinical data of 109 patients with hyperacute ischemic stroke were analyzed retrospectively, univariate analysis and multivariate logistic regression were used to observe the relationship between the volume and degree of initial supratentorial ischemia and CCD, respectively, and to further analyze the effects of CCD in the hyperacute phase on neurological function and clinical prognosis.
RESULTS: The degree and volume of initial supratentorial ischemia was significantly correlated with hyperacute CCD. The volume of ischemic penumbra (OR=1.021 [95% CI: 1.009-1.033], P<0.001) and the reduction rate of cerebral blood volume (CBV) (OR=1.338 [95% CI: 1.073-1.668], P=0.01) were the main influencing factors of CCD; patients with hyperacute CCD had higher admission and discharge National Institutes of Health Stroke Scale (NIHSS) (P=0.046 and P=0.01), and more hemorrhagic transformation (P=0.021), but there was no significant difference in the final infarction volume (P=0.347) and the 90-day modified Rankin Scale (mRS) (P=0.757).
CONCLUSION: Patients with CCD had larger initial supratentorial ischemic volume and more severe ischemic degree in the hyperacute ischemic stroke, more short-term neurological impairment, and worse short-term treatment effect, however, but the long-term functional prognosis was not be affected.
