Question
How should pediatric fibrotic congestive splenomegaly syndrome be treated? Recent symptoms of dyspepsia, abdominal pain, and black stools have been reported, and the diagnosis from the doctor is pediatric chronic congestive splenomegaly. What causes this condition?
Answer
The main cause of portal hypertension in childhood is the embolism of the portal vein and splenic vein. Splenic vein thrombosis may be related to neonatal umbilical inflammation, neonatal sepsis, complications of umbilical vein catheterization, cavernous hemangioma of the portal vein, congenital splenic vascular malformation, or abdominal mass compression. Portal hypertension can be divided into two types: extrahepatic and intrahepatic. Normally, 70% of the blood from the spleen vein flows into the hepatic vein. If there is a blockage in the portal vein, the blood returning to the spleen will be obstructed, which may lead to congestive splenomegaly. Even if the cause of the blockage is removed, the condition of splenomegaly may persist.
