目的：探索Willis环在分水岭脑梗死发生过程中的独特代偿作用。方法应用CT血管成像(CT an?giography,CTA)技术，回顾性分析2011年6月至2013年12月于我院住院治疗的471例急性非分水岭脑梗死和93例分水岭脑梗死（包括外侧型及内侧型两型）患者的颅内动脉，比较各组患者Willis环相关动脉的变异情况及构型特点。结果与非分水岭脑梗死相比，外侧型分水岭脑梗死患者中单侧胚胎型大脑后动脉明显增多(36.4%，P<0.05)，而内侧型分水岭脑梗死患者双侧胚胎型大脑后动脉明显减少(0%, P<0.05)，Willis环其余相关动脉变异及构型组成未见明显统计学差异(P>0.05)。结论与非分水岭脑梗死相比，胚胎型大脑后动脉与分水岭脑梗死有着独特关系。

Objective To explore the unique relationship between Willis circle and cerebral watershed infarction in a Chinese population. Methods A retrospective analysis of cerebral CT angiography was conducted in 471 non-cere?bral watershed infarctions and 93 MRI-diagnosed cerebral watershed infarctions (CWI)(including External CWI and In?ternal CWI)in Department of Neurology of our hospital and compare the related variations and types of Willis circle be?tween these groups. Results Compared with non-cerebral watershed infarctions, the prevalence of Uni-FTP (short for“fetal type of the Posterior cerebral artery”) in E-CWI (36.4%, P<0.05) and Bi-FTP in I-CWI (0%, P<0.05) was signifi?cantly higher in cerebral watershed infarctions. Conclusion FTP is probably an unique risk factor in Chinese patients with CWI.
