[Ultrasound-guided percutaneous transluminal angioplasty in the treatment of arteriovenous fistula immaturation: day surgery mode and clinical efficacy].

ABSTRACT

Objective: To summarize the clinical effect of ultrasound-guided percutaneous transluminal angioplasty (PTA) in the treatment of arteriovenous fistula (AVF) immaturation under day surgery mode. Methods: The clinical data was retrospective analyzed of patients with AVF immaturation who were treated by ultrasound-guided PTA under day surgery mode from November 2016 to June 2019 in Renji Hospital. The basic information, lesion location, puncture approach, number and diameter of balloon used were counted. The primary and secondary patency rates were calculated at 6 and 12 months after operation. Results: In all of the 21 patients, 11 patients were male and 10 patients were female. The mean age was (52.6±12.9) years old. There were 20 of the 21 patients who were treated successfully. One patient had AVF reconstruction with vascular rupture, and the complication rate was 4.8% (1/21). The length of hospitalization was (1.05±0.71) days, and the cost was (11 487.7±4 401.4) yuan. The follow-up time was (19.7±8.3) months. The 6-month and 12-month primary patency rate were 70% and 55%, and the 6-month and 12-month secondary patency rate were both 90%. Conclusion: Ultrasound-guided PTA in the treatment of AVF immaturation under day surgery mode is safe and effective, which has a high technical success rate and good patency rate for AVF maturation.
