Radiofrequency ablation of a recanalized renal arteriovenous malformation.
Radiofrequency (RF) ablation is becoming established as a method of treatment of small renal neoplasms. Successful RF ablation of a renal arteriovenous malformation (AVM) was performed in a patient who had previously undergone coil embolization and experienced hematuria after the feeding vessels recanalized. The 3.5-cm lesion was successfully treated with RF ablation, resulting in cessation of hematuria. At follow-up, there was no residual enhancement of the AVM on computed tomography and the lesion had decreased in size.
