Portal Hypertension

Portal hypertension happens when there is higher pressure in the portal vein, usually because of scarring in the liver. At North Shore Gastroenterology, we specialize in diagnosing and treating this condition, offering expert care and personalized support for liver disease.

What is Portal Hypertension?

Portal hypertension refers to elevated blood pressure in the portal venous system. Unlike systemic hypertension, which impacts the heart and blood vessels throughout the body, this condition specifically affects the portal vein—the vessel that transports blood from the stomach, intestines, and spleen to the liver.

In a healthy liver, blood flows smoothly. When the liver becomes damaged or scarred, this flow is blocked, creating increased pressure, like a kink in a hose. The buildup forces blood to bypass the liver, redirecting it into smaller, more fragile veins. This rerouting can lead to serious complications.

Causes and Risk Factors

The most common cause of portal hypertension is cirrhosis, or scarring of the liver. As scar tissue replaces healthy liver tissue, it hardens the liver and constricts the blood vessels within it, making it difficult for blood to pass through.

While cirrhosis is the primary driver, other causes include:

  • Blood clots.
  • Parasitic infections.
  • Focal Nodular Hyperplasia: A benign liver tumor that can press on the portal vein.
  • Congenital Abnormalities: Structural defects in the portal vein present at birth.

Symptoms of Portal Hypertension

Portal hypertension often won't show specific symptoms on its own. Instead, patients usually seek medical care once the increased pressure causes significant complications.

Common signs and complications include:

The high pressure forces blood into smaller veins in the esophagus or stomach. These veins can expand and rupture, causing you to vomit blood or pass black, tarry stools, requiring immediate medical attention.

Ascites is the buildup of fluid in the abdomen, which can lead to swelling, discomfort, and shortness of breath.

Confusion or forgetfulness is caused by the liver's inability to filter toxins from the blood, which then reaches the brain.

This is when the spleen becomes enlarged. It can trap and destroy blood cells, leading to low platelet counts and a higher risk of bleeding.

Swelling in the legs and feet.

Diagnosing Portal Hypertension

Because portal hypertension is a complex internal process, diagnosing it requires specialized evaluations, such as:

Your doctor will check for physical signs such as an enlarged spleen or visible veins on the abdomen.

Ultrasound with Doppler is often the first step to visualize blood flow through the portal vein. CT scans or MRIs may also be used to look for varices and assess liver structure.

This is a critical tool for identifying esophageal varices. A small camera is passed down the throat to visually inspect the veins in the esophagus and stomach for signs of dilation or bleeding risk.

Blood tests are conducted to check platelet counts and liver function.

Treating Portal Vein Hypertension

While treating the underlying liver disease is crucial, specific therapies are often needed to manage the pressure in the portal vein and prevent bleeding.

Management strategies include:

Non-selective beta-blockers are commonly prescribed to lower pressure in the portal vein and reduce the risk of bleeding.

During an endoscopy, rubber bands are placed around enlarged veins to cut off their blood flow and prevent them from rupturing.

A low-sodium diet is crucial for managing fluid retention. Patients are also strongly advised to avoid alcohol to protect their liver from further damage.

In severe cases, a stent is inserted in the liver to connect the portal vein to a hepatic vein, creating a pathway that reduces blood pressure.
