The mean splanchnic blood flow at baseline was 651 +- 76 mL/min, rising to a mean of 1,395 +- 230 mL/min after the meal (Fig. 1a). The oxygen content in the venous blood increased from a mean of 66 +- 1.5% at baseline to 71 +- 1.2% postprandial (Fig. 1b).
Digital subtraction angiography performed during the presented case (right) and 11 years earlier (left).

It verified the presence of more than 70% stenosis of both the celiac artery and superior mesenteric artery, along with an enlarged inferior mesenteric artery, with a clearly defined Riolan's anastomosis (Fig. 2). Comparing the present angiography with one performed 11 years back revealed similar findings (Fig. 2).

A 3D volume rendering based on the contrast-enhanced CT scan showed the same enlarged Riolan's anastomosis as the angiographs (Fig. 3).
