- Abstract: Objective To evaluate the effects of the multiple single cannulation technique(MUST)on the outcomes of arteriovenous graft(AVG).Methods A retrospective study of AVG created between January 2018 and December 2021 at the First Affiliated Hospital of Zhengzhou University was conducted.The clinical data of patients and their follow-up data for venous access were analyzed.Subjects were divided into the MUST group or the non-MUST group according to whether MUST was used.The cumulative patency rate and complication incidence were compared between the two groups.Logistic regression was applied to analyze the influencing factors of applying MUST in AVG.Results The MUST group included 115 AVG and the non-MUST group,122 AVG.The 1-year,2-year,3-year,and 4-year cumulative patency rates of the MUST group were 100%,99.1%,95.2%,85.4%,and 73.2%,respectively,while those for the non-MUST group were 97.5%,92.7%,77.7%,69.7%,and 50.0%,respectively,with the 2-year and 3-year patency rates showing significant difference(P=0.022,P=0.004).The standard intervention rate expressed in(median[interquartile range])in the MUST group was significantly lower than that in the non-MUST group(0.46[0.00,0.94]vs.0.97[0.60,1.59],Z=-5.808,P＜0.001).A total of 24(20.9%)AVG in the MUST group and 60(49.2%)AVG in the non-MUST group had a standard intervention rate＞1.0 per patient-year,with significant difference between the two groups.Three(2.6%)AVG in the MUST group and 7(5.7%)AVG in the non-MUST group were complicated by aneurysm(χ2=20.737,P＜0.001).One(0.9%)AVG in the MUST group and 6(4.9%)AVG in the non-MUST group had graft infection,with the difference between the groups showing no significance(P=0.121).Multivariate logistic regression showed that dialysis in the alliance facilities(odds ratio[OR]=2.713,95%confidence interval[CI]:1.698-4.336,P＜0.001],and excellent follow-up[OR=2.189,95%CI:1.221-3.927,P=0.009]were the influencing factors of applying MUST in AVG.Conclusion MUST improves the cumulative patency of AVG and decreases the intervention frequency and the incidence of aneurysm without increasing the risk of graft infection.
