RESUMO
compare the efficacy of percutaneous transluminal angioplasty (PTA) and neo-anastomosis in juxta-anastomotic stenosis of autologous arteriovenous fistula (AVF) of diabetic hemodialysis patients. Methods Diabetic patients with juxta-anastomotic stenosis in Beijing Tsinghua Changgung Hospital from February 2016 to December 2018 were retrospectively analyzed. The clinical data, success rate, patency time of PTA and vascular neo-anastomosis were compared. Results Thirteen patients received PTA, including 1 case of surgical failure and 1 case of thrombosis, and the success rate was 11/13. Vascular neo-anastomosis were performed in 15 cases, and 13 cases succeeded. The success rate was 13/15, and the success rate between two groups had no significant (P > 0.05). The median patency time was 11(7-12) months and 15(5-22) months (P>0.05). The volume of bleeding [3(2-4) ml vs. 20(10-40) ml], the length of blood vessel wastage [0 vs. (3.6 ± 1.2) cm] and the operating time [(0.6 ± 0.7) h vs. (1.8 ± 0.5) h] of PTA patients were less than those of vascular neo-anastomosis group, and there were significant differences (P < 0.05). Conclusions There are no significant differences between PTA and neo-anastomosis with respect to patency. PTA has the advantages of less vascular injury, shorter operation time, less bleeding and can dilate arteries at the same time.
