Portal stump pressure monitorization in the conscious rat after porta-caval shunt and total liver arterialization with the left gastric artery.
A method for portal stump pressure monitorization following arterialization is presented. Both intra and postoperative pressure determinations were performed and a significant difference between intra and postoperative values was observed. The pressure of the arterialized portal stump either using the left gastric artery or one of its branches, when compared to the free portal pressure did not reveal significant differences. According to these data, the proposed method of arterialization seems to create a "physiologic" arterialized stump pressure. This information while contributing to a better understanding of the complex hemodynamics of the arterialized liver represents essential guidelines for further studies on liver trophism and experimental portal hypertension.
