Contrast enhanced CT demonstrated complete PVT with cavernous transformation (Figure 1(a)) and clot extending into the distal SMV. A large splenorenal shunt and large upper abdominal varices were noted (Figure 1(b)).

MRI, intraoperative, and ultrasound imaging demonstrating (a) extensive esophageal varices (blue arrow), (b) a large perigastric varix used for portal inflow (green arrow), (c) the clamped varix, (d) an ileac vein graft anastomosed to the varix, (e) the porta postimplantation with varicoportal inflow and the overlying hepatic artery, and (f) Doppler imaging of the varicoportal inflow.

Preoperative imaging revealed cavernous transformation with numerous portal venous collaterals most prominent in the paraesophageal (Figure 2(a)) and perigastric regions (Figure 2(b)). Variant portal inflow was created by joining an ileac vein graft to a large perigastric varix (Figures 2(c)-2(f)).
