Abstract:
Objective To investigate the changes of vertebral-basal artery and regional cerebral blood flow(rCBF) in patients with olivopontocerebellar atrophy(OPCA).Methods 10 patients with OPCA were examined by digital subtraction angiography(DSA) and single-photon-emission-computed tomography(SPECT),and compared with the control group(patients with vertigo or transient ischemic attack).Results In OPCA group,there were 5 cases with small vertebral artery(50%),4 cases with single vertebral artery(40%),9 cases with small and little vessels(90%),10 cases with poor stain in later arterial phase(100%) could be seen by DSA.The lower rCBF in cerebellum and brain stem were seen in 8 cases(80%)by SPECT.In control group,there were 3 cases(15%),4 cases(20%),4 cases(20%),3 cases(15%) and 7 cases(35%) respectively.There were significant differences between the two groups(all P
