Hyperinsulinism Secondary to Congenital Portosystemic Shunt in a Neonate

Hong Yong Hee , Lee Dong Hoon , Kim Sung Shin

Background: Hyperinsulinism is a common cause of persistent hypoglycaemia in infant. Insulin secretion from pancreatic β-cells is unregulated and inappropriate for the level of blood glucose, causing glucose into the insulin-sensitive tissues, such as the muscle, liver and adipose tissue, leading to hyperinsulinaemic hypoglycaemia. But congenital portosystemic shunt, a rare vascular malformation, can cause hyperinsulinaemic hypoglycaemia rarely because glucose from portal...
