Arterial embolisation in renal carcinoma: a useful procedure?

Twenty-eight patients underwent embolisation over a 2-year period. III effects followed embolisation in 16 (57%), 2 of whom died. Attention is drawn to the intolerance of many patients to the length of the procedure. Of 24 patients undergoing operation, one case was inoperable and difficulty was encountered in 9. No perirenal plane of oedema was identified. No specimen examined histologically showed complete infarction. The tumour tissue was more resistant to infarction than normal kidney and 8 tumours (35%) appeared to have escaped completely. It is concluded that the role of embolisation is limited and that a combination of methods for achieving adequate arterial occlusion must be used for the optimum effect.
