Does the effect of small-diameter H-graft portacaval shunt on portal blood flow?
Small-diameter prosthetic H-graft portacaval shunts divert a significant amount of blood from the portal vein and significantly decrease portal pressures. The decreases in portal pressures with shunting are significant whereas changes in portal blood flow into the liver are not. These findings help explain the low incidence of variceal rebleeding and hepatic dysfunction after these shunts.
It was clearly observed that parents desire to know if their children with epilepsy require dietary restrictions and, hence, try to collect information from different and sometimes unreliable sources. It would be invaluable to consider the experience of families caring for epileptic children when evaluating the relationship between consumption of specific foods and seizures in future studies. This relationship may be due to a food-disease or food-drug interaction.
