🌿 What is EHPVO (Extrahepatic Portal Vein Obstruction)?

🧠 Understanding EHPVO: A Silent Yet Serious Condition

EHPVO, or Extrahepatic Portal Vein Obstruction, is a rare condition in which the main vein that carries blood to the liver (the portal vein) gets blocked or narrowed outside the liver. Despite this obstruction, the liver cells themselves are often healthy and functional, especially in early stages.

EHPVO is more common in children and young adults in developing countries like India, and it is one of the leading causes of portal hypertension (high pressure in the portal vein) in non-cirrhotic patients.

🧬 What Causes EHPVO?

The exact cause may not always be known, but several factors can contribute:

• Umbilical vein infections in newborns

• Abdominal infections or sepsis

• Hypercoagulable states (blood clotting disorders)

• Injury during abdominal surgery or trauma

• Idiopathic (unknown causes) — common in many Indian children

⚠️ Common Symptoms of EHPVO

Although liver function remains intact, symptoms arise due to increased pressure in the portal system, such as:

• Enlarged spleen (splenomegaly)

• Low platelet count (leading to easy bruising/bleeding)

• Varices (swollen veins in the esophagus), which can bleed

• Abdominal pain or fullness

• Stunted growth in children

• Fatigue and weakness

🧪 How is EHPVO Diagnosed?

EHPVO requires early detection and regular monitoring. Diagnostic tools include:

• Doppler Ultrasound: First-line tool to see portal vein blockage

• Contrast-enhanced CT or MRI: To assess vein anatomy and collaterals

• Upper GI Endoscopy: To check for esophageal or gastric varices

• Blood tests: To monitor platelet count and liver function

At Gleneagles Hospital, Mumbai, we use advanced imaging and non-invasive tools to confirm EHPVO and manage it long-term.

👨‍⚕️ How is EHPVO Treated?

There’s no single treatment for EHPVO — management is lifelong and preventive:

• Endoscopic band ligation or sclerotherapy to treat varices

• Beta-blocker medications to lower portal pressure

• Surgical shunt in select cases (Rex shunt in children)

• Regular growth monitoring in children

• Vaccinations and infection control

• Iron and multivitamin supplements
