Extrahepatic portal vein (PV) obstruction (EHPVO) is a rare disorder in early childhood with unknown incidence and mostly unknown etiology. In children with EHPVO, the hepatopedal flow of the mesenteric venous blood is hindered by an obstruction of the PV resulting in prehepatic portal hypertension. The curative treatment with a meso-Rex shunt connects the superior mesenteric vein to the left PV by a venous autograft. Despite good primary patency, reocclusion of a meso-Rex bypass and its treatment can be challenging. We present 2 patients with EHPVO with subtotal functional occlusion of a meso-Rex shunt treated by percutaneous interventions with short- and mid-term follow-up.
