PORTAL HYPERTENSION & SHUNT SURGERY (EHPVO/NCPF)

What Problems Can Portal Hypertension Cause?

Because of the high pressure, blood tries to find alternative pathways, leading to several complications:

1. Swollen veins (Varices)

• Veins in the food pipe (esophagus) or stomach become enlarged

• These veins are weak and can bleed suddenly, which is dangerous

2. Ascites

• Fluid collects in the abdomen

• Causes abdominal swelling and discomfort

3. Enlarged Spleen

• The spleen becomes large and traps blood cells

• Leads to low platelets, increasing bleeding risk

4. Bleeding

• Vomiting blood or passing black stools due to bleeding veins

5. Confusion (Hepatic Encephalopathy)

• Toxins build up in the blood

• Can cause sleepiness, confusion, or even coma

Common Symptoms

• Swollen belly

• Vomiting blood or black stools

• Easy bruising or bleeding

• Fatigue and weakness

• Confusion or poor concentration

• Loss of appetite

Some people may have no symptoms initially.

Why is portal hypertension dangerous?

High pressure in the portal vein can cause:

• Bleeding from food pipe veins (vomiting blood or black stools)

• Swollen spleen

• Fluid in the abdomen (ascites)

• Low blood counts

• Weakness and repeated hospital admissions

​

What is shunt surgery?

Shunt surgery is an operation where the surgeon creates a new pathway (shortcut) for blood to flow.

👉 Instead of blood trying to pass through the diseased liver, it is diverted to another vein, reducing the pressure.

Think of it like:

When a main road is blocked, a bypass road is created to reduce traffic.

Why is shunt surgery done?

Shunt surgery is usually done when:

• There is repeated bleeding from food pipe veins

• Medicines and endoscopic treatment fail

• The patient is young with good liver function

• Long-term solution is needed

Types of shunt surgery (simple idea)

Some common shunts include:

• Portocaval shunt

• Splenorenal shunt

• Mesocaval shunt

All of them aim to reduce portal pressure by diverting blood.

(You don’t need to remember the names—doctors choose based on the patient’s condition.)

What are the benefits of shunt surgery?

✔ Stops or prevents life-threatening bleeding
✔ Reduces portal vein pressure
✔ Improves quality of life
✔ Reduces need for repeated hospital visits

What are the risks or problems?

Like any major surgery, it has risks:

• Encephalopathy (confusion or altered behavior due to toxins bypassing the liver)

• Infection or bleeding

• Shunt blockage over time

• Surgery-related risks (especially in weak patients)

Life after shunt surgery

• Regular follow-up is needed

• Medicines may still be required

• Diet control (especially protein)

• Monitoring for mental changes

• Ultrasound or scans to check shunt flow

Is shunt surgery done for everyone?

❌ No.
It is not suitable for all patients, especially:

• Very advanced liver failure

• Elderly or very sick patients

Doctors carefully decide who will benefit the most.

​​​​Key Takeaway

Portal hypertension is a serious condition caused mainly by liver disease. Early detection, regular follow-up, and proper treatment can prevent life-threatening complications.​​​
