[Endovascular treatment of dysfunctional haemodialysis fistulas].
BACKGROUND
A native AV-fistula (AVF) is the first choice of access for haemodialysis. An important complication is thrombosis, which typically results from an underlying stenosis. In 2001, we introduced a surveillance program measuring the access flow (Qa). At the same time percutaneous transluminal angioplasty (PTA) was introduced as the first choice of treatment.


METHODS
Qa was conducted in a routine monitoring programme. Flow rates below a preset value indicated patient referral for angiography, and if the angiography revealed a significant stenosis, PTA was performed. In the period from August 2001 to March 2004, 71 angioplasties were performed in 52 patients.


RESULTS
The technical success rate was 66/71 (93%). Clinically significant complications occurred at a rate of 3/71 (4%). The 2-year primary patency rate was 36% and the primary assisted patency rate was 67%.


CONCLUSIONS
PTA in native haemodialysis fistulas was implemented. The rates of technical success, complications and patency were comparable with those recorded in the literature.
