Transcatheter obliteration of the renal artery by ethanol injection: experimental results.

The sclerosing effect of the introduction of 95% ethanol into the renal artery was evaluated in eight rabbits and one pig. Longterm occlusion of the renal artery with ensuing infarction of the kidney could be produced by a small, easily tolerated dose. Several inherent drawbacks of currently used embolic sgents may be avoided with this technique, which is suggested for clinical trial.
