Constriction of the thoracic IVC induced an increase in abdominal central venous pressure below the constriction within 12 weeks after surgery.

<p>Venous pressure measured in (A) the jugular vein above the constriction level and (B) the abdominal IVC below the constriction level in sham-operated (SHAM, n = 6) and IVC-constricted rats (IVCc, n = 7). Based on the Shapiro-Wilk normality test, data were analyzed using an unpaired t-test (A) or a Mann-Whitney test (B). Data are shown as median, minimum and maximum. ** denotes p < 0.01. CVP = central venous pressure, IVC = inferior vena cava, IVCc = IVC-constricted rats.
