This approach can lead to several complications, such as hyperkinetic heart failure due to a hyperfunctional AVF or dilatation of the feeding artery. These are late complications, especially in patients after a successful kidney transplantation. An observational study was performed focusing on patients more than 12\u00a0months after kidney transplantation. The AVF was evaluated by ultrasound and, if the outflow exceeded 1.5\u00a0L\/min, an echocardiogram was performed. Surgical management was indicated if the cardiac index was higher than 3.9\u00a0L\/min\/m<jats:sup>2<\/jats:sup> or upon finding a brachial artery aneurysm. A total of 208 post- kidney transplantation patients were examined over a 3-year period, of which 46 subjects (22.11%) had hyperfunctional AVF and 34 cases (16.34%) of feeding artery dilatation were determined. In total, 40 AVF flow reduction and 6 AVF ligation procedures were performed. The median AVF flow before and after the reduction was 2955\u00a0mL\/min and 1060\u00a0mL\/min, respectively. Primary patency after flow reduction was 88.3% at 12\u00a0months. Late AVF complications in patients following kidney transplantation are quite common. It is necessary to create a screening program to monitor AVFs in these patients.<\/jats:p>","DOI":"10.3389\/ti.2024.12841","type":"journal-article","created":{"date-parts":[[2024,8,12]],"date-time":"2024-08-12T16:20:29Z","timestamp":1723479629000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["Management
