摘　　要：目的探讨卵圆孔未闭(PFO)引起的隐源性缺血性脑卒中(CS)影像学诊断情况。方法入选2017年5月~2020年6月北部战区总医院PFO合并CS患者64例作为研究组,同时选取同期收治的非PFO所致CS患者64例设为对照组。两组均实施头部影像学检查,统计两组脑梗死病灶类型、梗死灶血管分布情况。结果研究组同一血管分布区伴散在小梗死灶融合率低于对照组(14%vs.30%,P<0.05),不同血管分布区域多发梗死灶率比例高于对照组(31%vs.14%,P<0.05);研究组与对照组的梗死灶分布于椎-基底动脉系统比例为(34%vs.14%,P<0.01),分布于大脑后动脉的比例为(36%vs.12%,P<0.01),研究组均高于对照组。研究组梗死灶分布于右侧颈内动脉系统率低于对照组(11%vs.34%,P<0.01)结论PFO所致CS影像学特征为多支血管分布区域的多发梗死灶且后循环梗死占优势。AIM To investigate the imaging diagnosis of cryptic ischemic stroke(CS)caused by patent foramen ovale(PFO).METHODS Sixty-four PFO patients combined with CS in the General Hospital of the Northern Theater Command from May 2017 to June 2020 were selected as the study group,and 64 CS patients without PFO at the same period were selected as the control group.Brain imaging examinations were performed and the types of cerebral infarction lesions and vascular distribution of infarction lesions in both groups were statistically analyzed.RESULTS The fusion rate of small infarcts in the same vascular distribution area in the study group was lower than that in the control group(14%vs.30%,P<0.05)and the rate of multiple infarcts in different vascular distribution areas was higher than that in the control group(31%vs.14%,P<0.05).The proportions in the study group distributed in the vertebrobasilar artery system and the specific involved vessel,posterior cerebral artery,were higher than those in the control group(34%vs.14%and 36%vs.12%,P<0.01).The percentage of infarction lesions in the right internal carotid artery system in the study group was lower than that in the control group(11%vs.34%,P<0.01).CONCLUSION The multiple infarcts in the multi-vessel distribution area are imaging features of PFO-induced CS,and moreover,posterior circulation infarction is dominant.
