Superselective Embolization of Arterial Bleeding as a Late Complication 3 Months After Nephron Sparing Surgery for Renal Cell Carcinoma

To our knowledge, this is the first case of an arterial bleeding as a late complication 3 months after nephron sparing surgery of renal cell cancer, presumably originating from an arteriocalyceal fistula. Superselective embolization of the feeding arterial branch was chosen for treatment of the hemorrhage and proved successful. The high efficacy of superselective embolization as a minimally invasive procedure in this and other cases of bleeding Vessels should be the preferred method instead of open surgery.
