Figure 3 (A) Angiographic findings of portal vein thrombosis of Case 3. Note that the portal vein trunk is completely thrombosed (arrowheads) and a large collateral vein (*) with marked cavernous transformation (**) has formed. (B) Intraoperative view of the Rex shunt created between the SMV and the UP using the donor’s external iliac vein. Note the shunt graft is tunneled through the prepancreatic retropyloric route. (C, D) A computed tomography scan taken at 3.3 years after the procedure shows a patent Rex shunt graft (C) and the UP of the graft (D). EIV – external iliac vein; UP – umbilical portion of the portal vein.
