Transluminal repair of large intrarenal arteriovenous fistulas.

Renal arteriovenous fistulas may be treated with radiological embolization or surgical ablation. Although recent reports in the literature have proposed embolization as the treatment of choice for renal arteriovenous fistulas, this form of therapy can be associated with significant morbidity in large arteriovenous communications. We report 3 cases of a large intrarenal arteriovenous fistula treated by transparenchymal repair. This technique offers an excellent method of obliterating the fistula without sacrificing the renal parenchyma.
