Figure 6 End-to-side portacaval shunt in the rat. The construction of a loop at the end of the suture facilitates the early approximation between the portal vein and the inferior vena cava, as well as its ending. Thus, when it reaches the end corner, the loop is untied by pulling on the end and the suture is tied to it. PV: Portal vein; IVC: Infrahepatic inferior vena cava.
