Transcatheter vascular occlusion was performed in 12 patients with renal cell carcinoma during the past four years. Gelfoam and blood clots were used in seven patients and the Gianturco stainless steel coil was used in five patients as occlusion material, along with anticancer chemotherapeutics. In four of the latter five patients, occlusion was done preoperatively to reduce tumor vascularity, and satisfactory results were observed during surgery. In a patient with inoperable renal cell carcinoma, embolizatiln was performed as a palliative measure to reduce tumor bulk. The steel coil is introduced into the renal artery, through a selectively placed preshaped non-tapered 7F polytetrafluoroethylene catheter in usual fashon. Epidural anesthesia with indwelling tube was performed prior to embolization in all our series, and it effectively relieved pain due to vascular occlusion. The occlusion with steel coil is apparently superior over that with other materials and almost permanent intravascular occlusion of the proximal portion of the renal artery was obtained.
