摘要
目的提高临床医生对Percheron动脉梗死的认识和诊断水平。方法总结4例Percheron动脉梗死的临床表现、影像特点、治疗及预后。结果 4例均急性起病,意识障碍后出现智能障碍及眼肌麻痹,按缺血性脑卒中治疗,患者临床症状均有改善。4例磁共振T1及T2加权像均见双侧丘脑旁正中碟形长T1长T2信号,3例磁共振弥散加权成像(DWI)示双侧丘脑旁正中以及中脑高信号,其中1例中脑为"V"字形高信号。结论以卒中样形式起病,有典型临床表现,结合MRI示双侧丘脑旁正中见碟形长T1长T2信号、DWI高信号及中脑"V"字征有助于Percheron动脉梗死的诊断。
Objective To improve the recognition and diagnosis of caused by Percheron artery occlusion. Methods The clinical features,imaging, treatment and prognosis of 4 cases were analyzed retrospectively. Re- suits All cases presented with acute onset of cognition dysfunction and ophthalmoplegia after consciousness disorders, and these clinical symptoms were ameliorated by ischemic stroke treatment. Imaging magnetic reso- nance showed phialiform with hypointensity on T1 WI and hyperintensity on T2 WI in bilateral paramedian thal- ami,and 3 cases had high signal on diffusion weighted imaging in bilateral paramedian thalamus and mesen- cephalen,one of which had a ＂V＂ signal in mesencephalen. Conclusions It is helpful to make the diagnosis of infarction of percheron artery occlusion based on the clinical manifestation combined with phialiform with hy- pointensity on T1 WI and hyperintensity on T2 WI in bilateral paramedian thalamus as well as hyperintensity on diffusion weighted imaging and the ＂V＂ sign in mesencephalen.
