Figure 14. MIP image from MR imaging data demonstrates the Michel type II variant, in which the replaced LHA (long solid arrow) originates from the left gastric artery (straight open arrow) and the MHA (short solid arrow) arises from the proper hepatic artery (curved open arrow). In cases of left lobe tumor, the surgical technique would have to be modified: The LHA would have to be ligated at its origin from the left gastric artery.
