Core Tip

Core Tip: Recanalized umbilical vein as a conduit for a Rex shunt was recently used to treat cavernous transformation of the portal vein. Fifteen children who received a recanalized umbilical vein as a conduit for a Rex shunt were included in group I, and the remaining 32 children who received a classic Rex shunt were included in group II. There was no difference in patency rate between the two groups after 3 mo of treatments. Diameter and flow velocity of bypass vessels in both two groups increased, and blood flow into the liver of both groups increased 3 mo after surgery.
