Correlation of thalamic blood flow redistribution with persistent complex regional pain syndrome in a stroke patient with poor diabetic control.
We present a right-hemispheric stroke patient with complex regional pain syndrome (CRPS). Symptoms of CRPS developed in conjunction with a corresponding elevation of the contralateral thalamic flow when the glycosylated hemoglobin values were high (16.1% and 13.4%), twice observed as migration from the bottom to the top location of the thalamus. CRPS improved after the glycosylated hemoglobin level reduced to 10.6% and 8.3%. Poor blood sugar control might cause redistribution of thalamic regional blood flow and be associated with the persistence of CRPS in this case.
