Nowadays the palliative treatment of hepatic metastasis very often uses the hepatic arterial chemotherapy in subcutaneous injection cavity. Unfortunately in about ten per cent of the cases, the thrombosis of hepatic artery limits the lasting quality of use of the catheters which last about twelve months (more or less four). As mentioned in our observation, if the patient "answers" the chemotherapy, we propose reusing this thrombosized artery by means of an original technical artifice. In this observation, in fact, we grafted a small segment of submesenteric vein on the hepatic disobstructed artery. We think that this artifice could also be used in case of anatomic variations of the hepatic artery like trifurcation.
