Hemodynamic changes after ligation of a major branch of the portal vein in rats: Comparison with rats with portal vein constriction
Soonho Um, Osamu Nishida, Masaki Tokubayashi, Fumiko Kimura, Yukinobu Takimoto, Hideyuki Yoshioka, Ryoichi Inque, Toru Kita – 1 January 1994 – In chronic portal‐hypertensive rat models, such as portal vein constriction or cirrhosis, the portal blood flow that effectively perfuses the hepatocytes is substantially reduced because of anatomical or functional shunts. It is possible therefore that a feedback mechanism from the liver to the splanchnic bed is responsible for the splanchnic hyperemia observed in chronic portal hypertension.
