[Revascularization of the hepatic artery. Apropos of a case]

A case of emergency revascularisation of the hepatic artery for liver necrosis following its forced ligature during corpo-caudal pancreatectomy for cancer of the pancreas in referred. Necrosis protection mechanisms, namely higher portal flow, increase in O2 extraction and collateral circulation are analysed. The therapeutic aids for preventing this serious event are presented. It is considered that peripheral expansion of the hepatic artery thrombosis prevented the installation of a valid collateral circulation, although the hypothesis of a reduction in portal flow should not be ignored.
