Percutaneous embolization of renal arteriovenous fistula.
Acquired renal arteriovenous fistula is a rare complication following a nephrectomy and its diagnosis may be made many years after the intervention. The closure of the fistula is advisable in most cases, since it represents a risk for heart failure and rupture of the vessel. There are an increasing number of publications describing different techniques of occlusion. The case of a 70-year-old woman with abdominal discomfort due to a large renal arteriovenous fistula, 45 years after nephrectomy, is presented and current literature is reviewed. Percutaneous embolization was performed by placing an occluding balloon through the draining vein followed by the release of nine coils through arterial access. One day after successful occlusion of the fistula, clinical symptoms disappeared.
