Right and left accessory hepatic arteries in liver donor: a technical challenge for vascular reconstruction

Case report

Liver graft donor with Michels type IV vascular anomaly: absence of common hepatic artery (CHA) with right and left accessory hepatic arteries from the upper mesenteric and left gastric arteries, respectively (Fig. 1A).

Fig. 1

Vascular reconstruction was performed in bench surgery by anastomosis of the LHA at the level of its origin in the left gastric artery with the gastroduodenal artery (GDA), a branch of the RHA (Fig. 1B). In the implant, arterial anastomosis was performed from the bifurcation of the recipient's CHA with the arch of the donor's variant RHA (Fig. 2, C1 and C2).
