Recordings were made in deeply anesthetized and laparatomized rats, with a cannula (BD Neoflon™ Cannula) connected to a pressure transducer (78534C MONITOR/ TERMINAL; Hewlett Packard, United States) inserted into the portal vein, inferior vena cava and abdominal aorta at the level of the bifurcation at 15 min, 24 h or 48 h post-ligation. Each recording lasted five minutes, being assessed in one minute intervals.
Notably, normal rats exhibited a portal pressure of 3–5 mmHg[25 (link)] similar to that of the inferior vena cava, though with at least 1 mmHg higher values in the portal vein. By contrast, abdominal aorta blood pressure values were 100–120 mmHg at the level of the bifurcation[21 (link)].
