Portal hypertension is a complication where pressure increases within the portal venous system. The portal vein forms by merging veins from the stomach, intestine, spleen, and pancreas. It then divides into smaller vessels and flows through the liver. Our body cannot circulate blood properly through the liver if there is any blockage due to liver damage. As a consequence, patients will experience high pressure in the portal system. It may lead to swollen veins (varices) in the esophagus, stomach, rectum, or umbilical region. Varices can rupture and bleed, posing a life-threatening danger.

Portal Hypertension in Cirrhosis
Cirrhosis of the liver is the most significant reason for portal hypertension. Cirrhosis is scarring that occurs after a liver injury , whether from hepatitis, alcohol, or other less frequent cause of liver damage. Cirrhosis causes increased resistance to portal blood in the liver. This increased resistance leads to back pressure in the Portal venous system leading to Portal hypertension.In patients with cirrhosis, portal hypertension is one of the most common causes of hospitalization, liver transplantation, even death. The best treatment for cirrhosis-related advanced portal hypertension is liver transplantation surgery.
Causes of Portal Hypertension, and to prevent it?
Other than the cirrhosis of the liver,
- Blood clots in the portal vein.
- Blockages of the veins that carry blood from your liver to the heart.
- A bacterial infection like schistosomiasis.
- NCPF. Non cirrhotic Portal hypertension
Symptoms of Portal Hypertension?
The symptoms of Portal hypertension are as follows:
- Due to a sudden rupture and bleeding from varices, patients may experience dark, tarry stools or blood in the stool.
- Patients may experience blood in vomiting too.
- There can be an accumulation of fluid in abdomen known as ascitis
- Patients may suffer from confusion and forgetfulness due to impaired liver function.
- The condition can lower platelet levels in your blood.
- Weight loss as a result of malnutrition.
- There can be Kidney malfunctions.
- Patients may experience fluid accumulation in your lungs.
What is the treatment for Portal Hypertension?
It is important to know the cause of portal Hypertension. In patients of cirrhosis , only therapeutic and permanent treatment is Liver Transplant. Till the patient is waiting for Liver transplant, the treatment revolves around preventing or controlling complications, especially variceal bleeding. Proper diet, medicines, endoscopic therapy, surgery, and radiology procedures are there to protect patients from any difficulties.
Endoscopic therapy: It consists of either banding or sclerotherapy. It is typically the first line of treatment for variceal bleeding. Banding is a process in which a gastroenterologist closes a blood vessel with rubber bands to avoid bleeding. Sclerotherapy involves insertion of a blood-clotting solution into the bleeding varices to prevent bleeding.
Medications:Your Doctor may suggest Nonselective beta-blockers (nadolol or propranolol) alone or with endoscopic therapy. It will reduce the risk of bleeding by lowering the varices pressure. Nonselective beta-blockers are also used to avoid first variceal bleeding in patients with varices and suspected of bleeding.
Changes in your lifestyle and diet: Stop drinking alcohol and avoid over-the-counter or prescription medications without consulting your doctor. These drugs can aggravate your condition.
Patients must adopt a low-sodium diet, which means the patient will have to cut down on their salt intake. Patients should limit their sodium intake to no more than 2 grams a day.
All of these are the primary treatments. If these treatments do not work, doctor may suggests:
- Transjugular intrahepatic portosystemic shunt (TIPS): It is a radiological method where doctors insert a stent in liver. Radiologist inserts a needle into liver to make a tunnel that connects the portal vein and hepatic veins. A metal stent is inserted into this tunnel to hold it open. This operation redirects blood flow through the liver and decreases pressure in portal veins, including those in the stomach, esophagus, bladder, and liver.
- Splenorenal shunt (SRS): In this surgical procedure, Surgeon connect the splenic vein to left kidney vein. It helps in controlling the pressure in varices and prevents bleeding. This procedure is advocated in Non Cirrhotic Portal hypertension( NCPH)
