[Long-term prognosis of portal hypertension in childhood]
Insights
Portal hypertension in children often involves a prehepatic block, commonly treated with umbilical vein catheterization. Definitive therapy involves a Warren-shunt for suitable candidates, while sclerotherapy offers palliative care for smaller children.
Area of Science:
- Pediatric Surgery
- Hepatology
- Vascular Surgery
Context:
- Prevalence of prehepatic portal hypertension in European children exceeds 70%.
- Many affected children have a history of umbilical vein catheterization.
- Portal hypertension significantly impacts pediatric gastrointestinal health.
Purpose:
- To outline definitive and palliative treatment strategies for pediatric prehepatic portal hypertension.
- To establish criteria for surgical intervention, specifically the Warren-shunt.
- To assess the long-term prognosis for children with prehepatic block and successful Warren-shunt.
Summary:
- Selective distal splenorenal shunt (Warren-shunt) is a definitive treatment for children with prehepatic portal hypertension and a splenic vein diameter ≥ 7 mm, confirmed by splenoportoseriography.
- Esophageal wall sclerotherapy serves as an effective palliative option for younger children with a splenic vein diameter < 7 mm.
- Children with prehepatic block who undergo a successful Warren-shunt procedure demonstrate a favorable prognosis.
Impact:
- Provides clear surgical guidelines for pediatric hepatobiliary conditions.
- Improves treatment outcomes and quality of life for children with portal hypertension.
- Highlights the importance of accurate vascular assessment in pediatric surgical planning.
Abstract:
In Europe more than 70 per cent of children with portal hypertension suffer from a prehepatic block. Most of them underwent an umbilical vein catheter treatment in postnatal anamnesis. Constructing a selective distal splenorenal shunt (Warren-shunt) is a definitive therapy. This operation is possible for children having a patent splenic vein with a diameter of at least 7 mm measured by splenoportoseriography. Sclerosing of the oesophageal wall is a good palliative treatment for small children with a diameter of the splenic vein of less than 7 mm. Children with prehepatic block and patent Warren-shunt have a good prognosis.
