Application Value of Autologous Arteriovenous Fistula and Human Hematopoietic Tube Fistula in Maintenance Hemodialysis Patients
Objective:To investigate the application value of autologous arteriovenous fistula(AVF)and human hematopoietic tube fistula(AVG)in maintenance hemodialysis patients,in order to improve the vascular revascularization rate and survival cycle of patients.Methods:A total of 96 patients with maintenance hemodialysis who visited the hospital from August 2019 to August 2021 were selected and divided into two groups with computer random number table method according to the visit number,with 48 patients in each group.AVG group received AVG hemodialysis treatment,and AVF group received AVF hemodialysis treatment.After 12 months of follow-up,the first patency rate,the second patency rate and the dialysis efficiency after hemodialysis were compared between the two groups.The levels of serum inflammatory factors,such as hypersensitive C-reactive protein(hs-CRP),β2 microglobulin(β2-mg),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)and the incidence of complications were compared between the two groups before treatment and 6 months after treatment.Results:Compared with AVG group,the first patency rate of blood duct path in AVF group was higher in 3 months,6 months and 12 months,with statistically significant difference(x2=16.336,12.303,12.462;P＜0.05).Compared with AVG group,the serum levels of hs-CRP,β2-MG,IL-6 and TNF-α in AVF group were lower after 6 months of treatment(t=5.312,5.857,6.877;P＜0.05).Compared with AVG group,the incidence of thrombosis,hemangioma,vascular stenosis and infection was lower in AVF group during treatment(t=18.581,15.791,34.687,16.336;P＜0.05).Compared with the AVG group,the incidence of thrombosis,hemangioma,vascular stenosis and infection was lower in the AVF group during treatment,and the difference was statistically significant(x2=6.008,4.174,16.232,7.551;P＜0.05).Conclusion:Both AVF and AVG have good effects on maintenance hemodialysis patients,among which AVF can be used as the preferred vascular pathway with a higher vascular patency rate.When there are limited factors,AVG can be selected as internal fistula.
