Abstract

Background: The present study is a prospective interventional study that investigates the effectiveness of balloon venoplasty in hemodialysis access disorders in ESRD patients and the clinical and anatomical factors affecting it.

Methods: Patients with impaired permanent hemodialysis access function (AVF, AVG) were included in the study and underwent venography and endovascular balloon venoplasty procedure. The effectiveness of the procedure was evaluated at one month, six months and twelve months after the procedure. After examining the patency rate in the intervals of one, six and twelve months, we examined the relationship between clinical and anatomical variables with the patency rate.

Results:Finally, the data and results of the remaining 48 patients were analyzed. We first looked at patency rate in different months after venoplasty; Patency rates in the first, sixth and twelfth months after venoplasty were 58.3%, 41.7% and 25%, respectively. The results showed that the patency in the first, sixth and twelfth months was not related to age, sex, diabetes, type of access (AVG and AVF), time from access implantation to stenosis and catheter presence. However, there was a significant relationship between patency in the first month, sixth and twelfth with the length of access. Also, there was a significant relationship between patency in the first month, sixth and twelfth with the degree of stenosis.

Conclusion: The present study suggests that balloon venoplasty treatment can be used as a minimally invasive treatment with good success in treating access disorders in dialysis patients, although patency decreases over time. Also, specialist physicians can use the results of this study to better predict the degree of patency after balloon venoplasty according to clinical and anatomical factors.
