[Experimental conditions for embolization treatment of renal hypertension].

An experimental study was carried out on 146 rats with hypertension in order to determine whether the intensive collateral circulation which develops in reno-vascular hypertension is responsible for the high failure rate following clinical embolisation. Ethibloc embolisation, which fills the capillaries, is as effective as nephrectomy, whereas ligature of the renal artery fails to affect the hypertension.
