[Embolization of benign non tumoral diseases of the kidney (author's transl)].
The material includes 11 traumatic lesions of the kidney after needle biopsy, one hemangioma of the kidney with arteriovenous fistula and 4 renal exclusions for malignant hypertension. In traumatic lesions of the kidney after needle biopsy, embolization was followed by 90,9 p. cent excellent, permanent results without any marked loss of renal parenchyma and with simple post-operative follow-up. A hemangioma with congenital arteriovenous fistula required complex embolization owing to multiple pedicles and caused devascularisation of part of the lower pole of the kidney. The clinical result was satisfactory, but an arteriographic control carried out as a routine 3 months later after the embolization showed the development of newly formed vessels around the renal pelvis. However, no relapse of the hematuria occurred after a follow-up of 2 years. During the same period, spontaneous disappearance of 3 hemangiomas of the kidney sent up for embolization was noted, which led us to treat only hemangiomas which bled and prefer embolization in order to keep the kidney intact. In malignant hypertension, embolization proved efficacious and lasting in one case of small unilateral kidney. Carried out in two stages in one case of chronic nephritis with small kidneys, it proved efficacious on one side, insufficient on the other and had to be followed by nephrectomy. Finally, embolization of a remaining kidney due to chronic glomerulonephritis, technically incomplete, was followed by an uncontrollable attack of hypertension with later death of the patient. The blood supply of the kidney must thus be interrupted completely and embolization should not be undertaken unless it appears technically possible. The degree of pain following embolization suggests the possibility of peridural anesthesia.
