Renal Artery Embolization in Treatment of Renal Cancer with Emphasis on Response of Immune System

RAE was introduced to clinical practice in the 70's of last century. The pioneers who devel‐ oped the technique of surgery were Lalli et al, in 1973 while Almgard et al. presented their own experience with the application of RAE in renal cancer in humans [2,3]. At that time arteriography was the basic diagnostic methods and identification of renal tumors was made during the embolization. Today, vascular embolization procedures are becoming widely used in the treatment of persistent bleeding, vascular defects and cancer.
