ABSTRACT

Aim: The aim of the study was to evaluate the results of endovascular treatment of arteriovenous fistula dysfunction at the Hospital of Lithuanian University of Health Sciences (LUHS) Kaunas Clinics.

Methods: Data of 125 patients, who underwent endovascular treatment of arteriovenous fistula disfunction at the Hospital of Lithuanian University of Health Sciences (LUHS) Kaunas Clinics between 1st January, 2016 and 31st December, 2018 were analyzed.

Results: The study population consisted from 80 male and 45 female. The average age of the participants was 61,73 ± 14,86 years. 36,1% patient had AVF stenosis, 87,2% of

them had just one stenosis site and 63,9% patient had occlusion. The most frequent localization of the occlusion or stenosis was at the site of AVF anastomosis – 68%.

Conclusions: 1. AVF occlusion was more frequent than stenosis. 2. Mostly AVF stenosis or occlusion were usually on one site. 3. Most often AVF stenosis or occlusion was found on the site of AVF anastomosis and rarely on the other localization.
