Abstract:
Objective:To investigate the predictive value of perirenal fat thickness(PrFT)of the assessment of computed tomography(CT)for vascular access-related events of elderly patients who received maintenance hemodialysis(MHD).Methods:A total of 160 MHD patients admitted to The 904th Hospital of People's Liberation Army Joint Service Support Force(Wuxi Taihu Hospital)from January 2021 to December 2023 were retrospectively selected.They were divided into event group(53 cases)and non-event group(107 cases)according to whether occurred vascular access-related events.Univariate and binary Logistics regression were used to analyze the influencing factors for vascular access-related events in MHD patients.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of PrFT for vascular access-related events of elderly MHD patients,and Pearson correlation was used to analyze the correlation among platelet(PLT)count,mean platelet volume(MPV)and PrFT.Results:There were statistically significant differences in PLT count,MPV and PrFT between the event group and non-event group(t=7.068,4.843,10.572,P<0.05),and the Binary Logistics regression analysis showed that PLT,MPV and PrFT were the influential factors for vascular access-related events of MHD patients(OR=0.963,2.483,1.284,P<0.05).ROC curve analysis showed that the area under curve(AUC)of ROC curve of PrFT was 0.880 in prediction,and the sensitivity and specificity of that were respectively 95.00%and 58.88%.According to Pearson's linear correlation analysis,PrFT was negatively correlated with PLT(r=-0.341,P<0.001),which was positively correlated with MPV(r=0.245,P<0.05).Conclusion:The PrFT of CT assessment has better predictive value in vascular access-related events of elderly MHD patients.
