Percutaneous transfemoral embolization of arterio-infundibular-venous fistula.

An arterio-infundibular-venous fistula complicating partial nephrectomy was embolized successfully via transfemoral catheterization of the right renal artery using autologous muscle. The use of autologous material occluded this vascular malformation with preservation of renal function in the remaining portion of the kidney. The technique was lifesaving since this patient was in critical condition and could not tolerate an operation.
