Abstract: 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.
