[Liver transplantation in the presence of a non-functional portal vein: an original technique].

Study Aim: The aim of this retrospective study was to report an original technique for heterotopic liver transplantation with the graft in the left hypochondrium, and to discuss the indications and limitations of this technique.

Patients And Method: Over the past ten years, four patients were treated by this technique; this constitutes 2% of all liver transplantations carried out during this period.

Results: No immediate per- or postoperative mortality related to the surgical procedure was noted. Moreover, no severe hemodynamic complications occurred during the per- or postoperative period. In three out of four cases, hepatic function was fully restored within 48 hours. Long-term survival (50 and 97 months) was observed in two patients.

Conclusion: Heterotopic liver transplantation in the left hypochondrium is an alternative to orthotopic liver transplantation; it is a technique that is easy, non-aggressive, and with good long-term results. It is indicated in cases where the main portal vein is non-functional (following total thrombosis or porto-caval shunt), and orthotopic liver transplantation is therefore not possible.
