title: [Renal arterial embolization for renal cell carcinoma].
abstract: Renal arterial embolization is often used in the treatment of patients with renal cell carcinoma, either preoperatively to facilitate nephrectomy or as palliative therapy in advanced cases. Eighteen patients (18/58; 31%) underwent renal arterial embolization in our department since 1979, initial 10 cases with Gelfoam and steel coil (group G) and recent 8 cases with absolute ethanol (group A). Clinical studies of daily changes of symptoms and blood chemistry in both groups after embolization were compared and the results were as follows: Severe flank pain was noted immediately after embolization but thereafter well controlled without analgesics in group A. The patients in group G experienced no pain during the procedure of embolization but have had moderate flank pain of two or three days' duration with nausea and/or vomiting and required surgical procedure within a few days after embolization. Post embolization fever in group A was described as higher than that in group G significantly. Leukocytosis was noted to be persistent for up to seven days and blood chemistry showed transient marked elevations of GOT, GPT and LDH immediately after the procedure without significant value in both groups. Embolization to advanced tumor with many parasitic vessels or massive local invasion may not always be available for remaining of viable-appearing tumor cells in venous lumen, as if palliative treatment. Absolute ethanol may be more useful as the embolizing substance than Gelfoam and steel coil by reason of producing wide severe infarction of diseased kidney. Broad marked infarction due to renal arterial embolization may make pathological diagnosis difficult. Immunological effects of renal arterial embolization were not observed in short term patients survival.(ABSTRACT TRUNCATED AT 250 WORDS)
