【摘要】Objective To investigate the correlation between ≥50% apparently symptomatic vertebral stenosis and the brainstem/cerebellar infarction. Methods 54 patients with≥50%apparently symptomatic vertebral stenosis detected by 256-multislice CT angiography (CTA) were
admitted
retrospectively.

brainstem/cerebellar infarction. The symptomatic vertebral artery stenosis characteristics in brainstem/cerebellar infarction were analyzed. Results Lacunar infarction in brainstem infarction group due to vertebral artery stenosis was significantly more than ter-ritorial infarction (χ2=7.84, P<0.05). Territorial infarction in cerebellar infarction group was significantly more than la-cunar infarction (χ2=10.71, P<0.01). Atherosclerotic plaques were found in 45.45%/71.43%of the cases with brainstem/cerebellar infarction respectively. Vertebral artery hypoplasia was found in 18.19%/14.29%of the cases with brainstem/cerebellar infarction respectively. The intracranial vertebral artery (V4 segment) stenosis was significantly higher in the brainstem infarction group (42.37%) than that in the cerebellar infarction group (22.44%, χ2=6.25, P<0.05). The prox-imal vertebral artery (V1 segment) stenosis was
