[Embolization of renal artery -- an alternative in nephrectomy in the treatment of patients with dialysis and malignant hypertension (author's transl)].

Embolization of renal arteries (coil embolization by Gianturco) was performed in four patients with malignant renal hypertension as an alternative to bilateral nephrectomy. Three patients with successful renal transplantation developed intractable hypertension without arterial stenosis of the transplant. One patient treated with hemodialysis showed malignant hypertension refractory to volume depletion and antihypertensive therapy. In all cases hypertension could be improved and thus medical therapy be reduced.
