Provided that an efficient embolization must be complete, distal and irreversible or at least long-lasting, we can state that both Gelfoam and cyanoacrylates are qualified embolic materials for preoperative embolization of kidney tumors. However, we believe that some considerations can make cyanoacrylates preferable: 1) the greater efficacy in distal occlusion, and therefore in collapsing collateral venous circulation; 2) the irreversibility of the occlusion, which may be useful when successive complications eliminate the possibility of surgical intervention; 3) the useful training with a very interesting embolic material, which can be used with advantage in other embolizations (hypogastric arteries embolization, closure of a-v fistulas); 4) the advantage of radioopacity which is obtained by mixture with Lipiodol. It ensures a very good control of the embolizing injection and visualization of the embolus in the case of accidental embolism. It is also easier to follow-up by simple standard x-ray examination. Finally, the results of the histological study presented confirmed that cyanoacrylates are, in our opinion, the embolic material of choice in tumoral embolization. Gelfoam is a valid alternative material when technical difficulties make the use of acrylic emboli hazardous.
