摘　　要：Percheron动脉(AOP)是丘脑旁正中动脉的一种解剖变异形式,随着影像技术的发展,AOP受到越来越多的关注。现报道1例AOP闭塞所致双侧丘脑梗死的病例,其特点是双侧丘脑梗死呈进展性,但早期弥散加权成像未随卒中进展而出现相应弥散受限信号,多次复查后方出现与症状相符的影像学表现。通过本例患者并回顾相关文献资料,探讨AOP梗死可能的发病机制、临床表现和影像学特征,以期提高对此类疾病的诊治水平。The artery of Percheron(AOP)is an anatomical variation in the paramedian thalamic artery.With the development of imaging technologies,the AOP is attracting more and more attention.In this article,a case of AOP occlusion-induced bilateral thalamic infarction was reported;the case was characterized by progressive bilateral thalamic infarction which showed no diffusion-limited signals on early diffusion-weighted imaging with progression of the stroke and later showed radiological features consistent with the symptoms only after multiple reexaminations.Through analysis of this case and review of relevant literature,the pathogenesis,clinical manifestations,and radiological features of AOP infarction were investigated,with an expectation of improving the diagnosis and treatment of such diseases.
