OBJECTIVE
Thrombosis of a hemodialysis arteriovenous fistula (AVF) is a serious complication that needs urgent treatment. Most cases are treated surgically, but recently, endovascular strategies have become a viable alternative. This study is an evaluation of the success and patency rate of percutaneous balloon angioplasty of thrombosed hemodialysis fistulas using a drug-coated balloon (DCB) contrasted with a standard balloon (SB).

METHODS
The data of 33 patients with a thrombosed native hemodialysis AVF treated percutaneously in a tertiary care center were analyzed retrospectively. Success of the procedure was defined as restoration of flow with less than 30% residual stenosis and resumption of dialysis through the hemodialysis AVF. The success rate of the procedure and the patency rate at 1, 6, and 12 months were evaluated. The effect on patency of a DCB was compared to that of a SB.

RESULTS
Twenty-five radiocephalic and 8 brachiocephalic thrombosed hemodialysis AVFs were treated during the study period. Flow was restored in 23 thrombosed fistulas, a success rate of 69.7%. The patency rate of successfully treated fistulas was 95.6% at 1 month, 76.1% at 6 months, and 57.9% at 12 months. Ten of the 23 re-established AVFs were treated with a DCB and the remainder were treated with a SB. The patency of the fistulas treated with a DCB was similar to that of a SB at 1 month (100% vs 92.3%, respectively; p=0.393). The patency rate of a DCB was greater than that of a SB at 6 months (88.9% vs 66.7%, respectively; p=0.258) and 12 months (75% vs 45.4%, respectively; p=0.219).

CONCLUSION
Percutaneous intervention for thrombosed hemodialysis AVFs is a safe, minimally invasive, and effective procedure. There was a positive trend in the patency rate of patients treated with a DCB at 6 and 12 months compared with a SB.
