Factors influencing early progression of acute solitary pontine infarction / 中华老年心脑血管病杂志

ABSTRACT

Objective To analyze the factors influencing the early progression of acute solitary pontine infarction (ASPI).Methods 146 patients with head MRI-confirmed ASPI were divided into neurological deficit progression group (A group,n=30) and non-neurological deficit progression group (B group,n=116) according to their NIHSS score.Their clinical and imaging characteristics were analyzed.Results The acute neurological dysfunction was severer,the outcome was poorer,the hospital visiting time was longer,the infarction size was larger in A group than in B group.The incidence of infarction involving ≥2 layers and basilar artery stenosis,the stenosis rate of basilar artery stenosis and other intracranial vessels,and the percentage of NIHSS and mRS score at discharge were significantly higher in A group than in B group (76.6％ vs 37.9％;30.0％ vs 7.7％;46.6％ vs 6.0％;50.0％ vs 21.5％;80.0％ vs 15.5％,P＜0.05,P＜0.01).Conclusion The progression is faster and the infarction size is larger in ASPI patients than in cerebral stroke patients,which are related with the involved layers,stenosis of basilar artery and other intracranial vessels,and can thus play an important role in judging the early outcome of ASPI patients.
