Comments on “Liver resection using total vascular exclusion of the liver preserving the caval flow, in situ hypothermic portal perfusion and temporary porta-caval shunt: a new technique for central tumors”

We read with great interest the article by Azoulay et al. (1), published in Hepatobiliary surgery and nutrition, about total vascular exclusion (TVE) of the liver with preservation of the caval flow using in situ hypothermic portal perfusion and temporary porto-caval shunt (PCS) in centrally located tumors. We would like to praise the authors for their technical skills in performing such extreme liver resections and we would like to deeply discuss some technical aspects.
