目的：探讨高龄后循环脑梗死患者的发病危险因素、临床表现、影像学特点和预后。方法选择522例老年急性后循环脑梗死患者，依据年龄分为高龄组152例（≥80岁）和老年组370例（60～79岁）。比较2组患者的临床症状、影像学资料和发病危险因素，并在病后30d进行改良Rankin量表评估分析预后。结果与老年组比较，高龄组头晕和双侧肢体乏力、心房颤动比例明显升高（42．11％vs29．73％、7．89％vs3．24％、17．11％vs10．00％，P＜0．05，P＜0．01）。高龄组最常累积后循环血管的中段和远段。与老年组比较，高龄组枕叶单发梗死和多发梗死明显升高；预后不良比例明显升高（28．29％vs17．57％，P＜0．01）。结论高龄后循环脑梗死患者在发病危险因素、临床表现以及影像学特点均与老年后循环脑梗死患者存在差异，高龄后循环脑梗死患者预后相对较差。

Objective To study the risk factors ,clinical manifestations ,radiological features and outcome of advance-aged posterior circulation ischemic stroke patients .Methods Five hundred and twenty-two posterior circulation ischemic stroke patients with their age ≥60 years were di-vided into ≥80 years old group (n=152) and 60 -79 years old group (n=370) .Their risk fac-tors ,clinical manifestations ,radiological data and outcome were compared according to the modi-fied Rankin Scale (mRS) on day 30 after onset of posterior circulation ischemic stroke .Results The incidence of dizziness ,bilateral limb weakness and atrial fibrillation was significantly higher in ≥80 years old group than in 60-79 years old group (42 .11% vs 29 .73% ,7 .89% vs 3 .24% , 17 .11% vs 10 .00% ,P<0 .05 ,P<0 .01) .The most commonly involved were the middle and distal segments of posterior circulation vessels in advance-aged posterior circulation ischemic stroke pa-tients .Occipital lobe infarction was more common and the outcome was poorer in ≥80 years old group than in 60-79 years old group (28 .29% vs 17 .57% ,P<0 .01) .Conclusion The risk fac-tors ,clinical manifestations and radiological features of advance-aged posterior circulation ischemic stroke patients are different from those of aged posterior circulation ischemic stroke patients .The outcome is poorer in advance-aged posterior circulation ischemic stroke patients than in aged pos-terior circulation ischemic stroke patients .
