Abstract:
Objective:To investigate the relationship between the degree of basilar artery stenosis and the short-term prognosis in patients with isolated pontine infarction.Methods:One hundred and thirty-seven patients with isolated pontine infarction within 1 month after symptom onset admitted to our hospital from April 2016 to April 2018 were consecutively included.Based on modified Rankin scale(mRS)socres, patients were divided into the good outcome group(mRS score≤2)and the poor outcome group(mRS score>2). Venous blood samples were taken for biochemical testing on admission or the next day.Baseline National Institutes of Health Stroke Scale(NIHSS)scores and demographic data were recorded and compared between the two groups.The degree of basilar artery stenosis was assessed by magnetic resonance angiography(MRA), and subjects were divided into the non-stenosis, mild stenosis, middle stenosis and severe stenosis subgroups.Results:There were 108 patients in the good outcome group and 29 in the poor outcome group.The baseline NIHSS score(2.71±0.22 vs.7.10±0.59, t=6.99, P<0.01)and total cholesterol[(4.29±0.101)mmol/L vs.(4.76±0.17)mmol/L, t=2.21, P=0.03]were lower in the good outcome group than in the poor outcome group.The proportion of patients without stenosis was higher(76 or 70.4% vs.5 or 17.2%, χ2=26.70, P<0.01)and the proportion of patients with severe stenosis were lower(4 or 3.7% vs.7 or 24.1%, P=0.002)in the good outcome group than in the poor outcome group.Binary logistics regression analysis showed that baseline NIHSS score( OR=1.658, 95% CI: 1.327-2.071, P=0.000)and degree of basilar artery stenosis( OR=2.071, 95% CI: 1.159-3.701, P=0.014)were risk factors for the short-term prognosis. Conclusions:The degree of basilar artery stenosis is a risk factor for the short-term prognosis in patients with isolated pontine infarction, and patients with severer stenosis will have a poorer prognosis.
