The Present Day Usage of Nonselective Shunts

Abstract: The term “nonselective shunt” applies to a portal deviation which decompresses the entire portal system, in contrast to a “selective shunt” which decompresses only a portion of the portal vasculature. The nonselective shunts can be identified by their anatomical position: portacaval, mesentericocaval or splenorenal. These shunts can also be described by the degree to which they decompress the entire portal flow: “total” in which the portal pressure is reduced to approximately the systemic venous pressures, and “partial” in which only a restricted amount of portal flow is deviated into the systemic venous system, hence “taking the head off the pressure” and reducing the risk of variceal bleeding while maintaining hepatopetal flow [1].
