EEM embolization (03L-326).

A. Normal selective right renal arteriogram (magnification 1X).

B. Selective right renal angiogram 1-week post VX-2 tumor inoculation: Several peripheral branches are occluded at the interlobar-interlobular-arcuate level throughout the kidney, the intensity of the parenchymal staining is slightly uneven (magnification 1X).

C. Selective right renal arteriogram obtained 3-weeks post EEM embolization: The right renal artery is occluded, except for a 1-cm long stump that carries the patent capsular artery. The capsular artery increased in caliber, (its branches supply the perirenal soft tissue), but there is no parenchymal staining. Note that the right kidney is slightly reduced in size with moderately increased radiopacity, indicating residual Ethiodol and mineralization (normal view).
