Abstract: Objecctive To evaluate the treatment of arteriovenous fistula rupture during endovascular manipulationt for graft and fistula. Methods In the period from April 2012 to July 2016, arteriovenous fistula rupture happened 7 times in 200 patients during endovascular manipulation in our hospital. Six ruptures happened intraoperatively, and one was of delayed rupture. Covered stents were implanted in 4 of these ruptures, 2 patients refused further treatment, and one patient was treated with compression. Results Covered stents were successfully implanted for the 4 patients, and the fistulas could be used for blood access immediately, However, dysfunctioning of the fistula due to vascular proliferation occurred in one patient after stent implantation for 6 months. The other 3 patients were followed up for 1 to 20 moths without recurrence of rupture and stenosis. Conclutions Hemodialysis access rupture is a rare but serious complication during endovascular manipulation. Covered stent provided a safe and effective treatment for this complication.
