Comparison of the efficacy and safety of three different operation methods in the treatment of arteriovenous fistula type Ⅰ stenosis
Objective To investigate the efficacy and safety of three different operation methods in the treatment of arteriovenous fistula type Ⅰ stenosis.Methods 54 patients with arteriovenous fistula type Ⅰ stenosis admitted to our hospital from January 2019 to January 2024 were se-lected as the study objects,and divided into percutaneous transluminal angioplasty group,internal fistula reconstruction group and double fistula re-construction group according to random number table method,with 18 cases in each group.Clinical follow-up was performed for 12 months after surgery in all three groups,and the patency rate of internal fistula at 3,6 and 12 months after surgery was recorded in detail,and the incidence of postoperative hematoma and puncture point bleeding was compared among the three groups.Results The internal fistula patency rates of patients in the double fistula reconstruction group and the internal fistula reconstruction group were significantly higher than those in the percutaneous en-dovascular angioplasty group at 3,6 and 12 months after surgery(P＜0.05),while the internal fistula patency rates of patients in the double fistula re-construction group and the internal fistula reconstruction group at 3,6 and 12 months after surgery had no statistical significance(P＞0.05).The inci-dence of postoperative hematoma and puncture point bleeding in the double fistula reconstruction group and the internal fistula reconstruction group was significantly lower than that in the percutaneous endovascular angioplasty group(P＜0.05),while the incidence of postoperative hematoma and puncture point bleeding in the double fistula reconstruction group and the internal fistula reconstruction group had no statistical significance(P＞0.05).Conclusion The efficacy and safety of internal fistula double fistula reconstruction and internal fistula resection and reconstruction in the treatment of arteriovenous fistula type Ⅰ stenosis are superior to that of percutaneous transluminal angioplasty,and suitable surgical treatment can be selected according to the patient's condition.
