Abstract：Objective To explore the safety and effectiveness of ultrasound-guided balloon dilatation in the treatment of arteriovenous fistula stenosis of upper extremities for hemodialysis patients.Methods Forty patients with hemodialysis treatment and upper extremity arteriovenous fistula stenosis in our hospital from January 2016 to January 2018 were enrolled in the study.They were divided into control group and observation group according to the random number table method, 20 cases in each group.Patients in the control group underwent balloon dilatation under digital angiography, and patients in the observation group underwent ultrasound-guided balloon dilatation.The balloon dilatation effect(number of balloon dilatation, balloon dilation pressure, the success rate of surgery) and vascular diameter and dialysis blood flow before and after dilatation were compared between the two groups, and follow-up results were recorded.Results The number of balloon dilatation in the observation group was significantly fewer than that in the control group,the balloon dilatation pressure and the success rate of surgery were higher than those in the control group, and the differences were statistically significant (P<0.05).There were no significant differences in the vascular diameter and dialysis blood flow between the two groups before dilatation (P>0.05).The vascular diameter after dilatation in both groups was greater than that before dilatation, the dialysis blood flow was more than that before dilatation, and the differences were statistically significant (P<0.05).The vascular diameter after dilatation in the observation group was greater than that in the control group, the dialysis blood flow was more than that in the control group, and the differences were statistically significant (P<0.05).In the study, 40 patients underwent balloon dilatation alone,and 38 patients (95.00%) were successfully opened after interventional therapy.The proportion of patients whose internal fistulas remained open for 3, 4, 5, and 6 months during subsequent hemodialysis were respectively 95.00%,82.50%, 75.00%, and 67.50%.Conclusion The ultrasound-guided balloon dilatation is safe and effective in the treatment of upper extremity arteriovenous fistula stenosis in hemodialysis patients, and it is worthy of promotion and application in clinical practice.
