Clinical outcomes following endovascular treatment of the malfunctioning autologous dialysis fistula.

Abstract：

BACKGROUND:There is limited long-term prospective data on the use of endovascular techniques and the use of thrombolysis in malfunctioning autologous haemodialysis fistulas. PURPOSE:Prospective assessment of clinical outcomes following angioplasty with or without low-dose thrombolysis was undertaken in patients who presented with malfunctioning autologous haemodialysis fistulas. METHODS:Consecutive patients referred to our department over a 6-month period were included. Twenty-five patients underwent percutaneous intervention by angioplasty alone (n = 14), angioplasty and stent (n = 2), thrombolysis alone (n = 2), angioplasty, thrombolysis and stent (n = 2) and angioplasty and thrombolysis (n = 5). Patients underwent clinical follow-up and were reviewed at 6, 12, 18 and 24 months to determine fistula status. Thirty-day mortality in the group was two patients. Statistical analysis was performed with Mann-Whitney, chi-squared and Kruskal-Wallis tests. Kaplan-Meier curves were constructed to compare primary and secondary patency rates. RESULTS:Technical success and initial clinical success rates were 88% and 76%, respectively. Primary and secondary clinical success rates at 6 months were 68% and 72%, at 12 months were 68% and 72%, at 18 months were 60% and 68% and at 24 months were 52% and 68%, respectively. There were no major complications following interventional procedures. There were four minor complications. After an initially successful procedure, five patients required subsequent intervention during the follow-up period. The overall fistula event rate was very low (five per 600 patient months or 0.0996 per access year) with a fistula loss rate of 0.14 per access year. CONCLUSIONS:Our results confirm that excellent clinical results can be achieved by percutaneous endovascular treatment in malfunctioning autologous fistulas, justifying their continued use as first-line management.
