                  Under pathological conditions, venovenous ‘bypasses’ open to decrease hypertension in the portal vein system. These are enlarged existing venovenous anastomoses: Portocaval anastomoses. The following major routes can be distinguished (Luzsa G 1972 Röntgenanatomie des Gefäßsystems. Akadémiai Kiadó, Budapest; Kachlik et al. 2021 Bosn J Basic Med Sci 21:208-220).
