Ethanol for hepatic artery embolization.

Reflecting on the studies by O'Riordan et al. and Doppman and Girton that are reported in this issue, the authors discuss the safety of using ethanol for hepatic artery embolization (HAE) and stress that the optimal indications for this procedure are still to be established. They indicate that the caution necessary with any technique can direct rather than inhibit action.
