Clinical characteristics of advance-aged posterior ci rculation ischemic stroke patients
Abstract：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 .
