Abstract:

Objective To observe the effect and restenosis rate of ultrasound-guided balloon dilatation in the treatment of arteriovenous fistula stenosis. Methods The clinical data of 78 patients with arteriovenous fistula stenosis were retrospectively analyzed. The above patients were grouped by different surgical methods. Thirty-eight patients who received balloon dilatation under digital subtraction angiography (DSA) were included in the DSA group, and 40 cases who adopted ultrasound-guided balloon dilatation were enrolled as the ultrasound-guided group. The surgical conditions (success rate of one-time puncture, surgical time, intraoperative blood loss and postoperative fistula starting time) were observed in the two groups of patients. The postoperative clinical indicators, postoperative restenosis and occurrence of postoperative complications were compared. Results Compared with the DSA group, the success rate of one-time puncture, was higher, and the surgical time was shorter in the ultrasound-guided group (P<0.05), but there were no significant differences in the intraoperative blood loss and postoperative fistula starting time between the two groups (P>0.05). The internal diameter, dialysis blood flow volume, internal fistula natural blood flow and cross-sectional area of the arteriovenous fistula stenosis were increased at 7 days after surgery compared with those before surgery in the two groups (P<0.05). The internal diameter, dialysis blood flow volume and internal fistula natural blood flow in the ultrasound-guided group at 7 days after surgery were significantly higher than those in the DSA group (P<0.05). There was no significant difference in postoperative cross-sectional area between the two groups of patients (P>0.05). No restenosis occurred within 1 month after surgery in the two groups, and there was no significant difference in the restenosis rate at 3 months after surgery between the two groups of patients (P>0.05). The restenosis rates at 6 and 9 months after surgery were lower in the ultrasound-guided group than those in the DSA group (P<0.05). There was no statistical difference in total incidence rate of postoperative complications between the two groups of patients (P>0.05). Conclusion Ultrasound-guided balloon dilatation in the treatment of arteriovenous fistula stenosis can effectively improve the inner diameter of the stenosis, exhibit quick surgery and increase the dialysis blood flow volume. In addition, it has low risk of restenosis and few postoperative complications.
