Successful treatment of intimal hyperplasia in renal arteries by endovascular brachytherapy.
OBJECTIVE
The present study shows the possibility of preventing restenosis of renal arteries by endovascular brachytherapy.


METHODS
We present a patient suffering from rapid restenosis of both renal arteries with decreasing renal function. Percutaneous transluminal angioplasty (PTA) and stent implantation were unable to stop hypertension and to stabilize renal function. Both renal arteries and the right pole artery were treated by endovascular brachytherapy in one session.


RESULTS
Six months after intervention, intraarterial digital subtraction angiography (DSA) showed no evidence of recurrence, and the blood pressure remained normal without medical treatment.


CONCLUSIONS
Endovascular brachytherapy can help to prevent restenosis in renal arteries. It is possible to treat both renal arteries and one pole artery in one session without any disadvantage.
