Abstract:
Objective To explore the correlation between the elder brain atrophy and calcification score at siphon segment of internal carotid artery.Methods The brain CT examination was detected in 327 elders.The brain atrophy occurrence were observed, and the calcification score at siphon segment of internal carotid artery were determined and calculated.Accroding to the calcification score, all the cases were divided into calcification 0 score group, calcification 1-199 score group, calcification 200-399 score group, calcification 400-599 score group and calcification ≥600 score group.The situation of brain atrophy were compared among these groups.And the correlation between the brain atrophy and calcification score were analyzed.Results Accroding to the calcification score, there were 63 cases in calcification 0 score group, 133 cases in calcification 1-199 score group, 72 cases in calcification 200-399 score group, 28 cases in calcification 400-599 score group and 31 cases in calcification ≥600 score group.There were 13 cases ( 20.63%) of brain atrophy in calcification 0 score group, 64 cases (48.12%) in calcification 1 -199 score group, 51 cases (70.83%) in calcification 200 -399 score group, 23 cases (82.14%) in calcification 400-599 score group and 28 cases (90.32%) in calcification≥600 score group;the differences of the brain atrophy rate among these groups were statistical significant ( all P<0.05 ) .The brain atrophy was mainly mild-moderate in calcification 0 score group and calcification 1 -199 score group;which was mainly severe in calcification 200 -399 score group;and mainly moderate-severe in calcification 400 -599 score group and calcification≥600 score group (all P<0.05).Spearman rank correlation analysis showed that the degree of brain atrophy were positive correlated with calcification score at siphon segment of internal carotid artery ( r=0.717, P<0.05) .Conclusions The elder brain atrophy is significantly correlated with calcification score at siphon segment of internal carotid artery.The calcification score higher, the brain atrophy rate higher and the degree more severe.Calcification score can be used as an important indicator of the elder brain atrophy.
