Portal Hypertension
Portal hypertension occurs when blood flow through the liver becomes blocked or slowed, usually due to scarring from cirrhosis. This increased pressure in the portal vein can lead to complications such as enlarged veins (varices), abdominal fluid buildup (ascites), and enlarged spleen (splenomegaly).
At The Medical Group of New Jersey, our hepatologists use advanced imaging and endoscopic techniques to diagnose and manage portal hypertension, helping to reduce complications and improve long-term liver health.
Symptom Onset & Initial Evaluation
Portal hypertension itself may not cause symptoms, but its complications often do. Common signs include:
- Abdominal swelling or bloating from ascites
- Enlarged veins visible on the abdomen or legs
- Vomiting blood or passing black stools (a sign of variceal bleeding)
- Low platelet counts or anemia on routine labs
- Fatigue or confusion in advanced cases
During your evaluation, your hepatologist will review your history of liver disease, medications, and any previous bleeding or swelling. A physical exam and lab tests help assess the extent of portal hypertension and its effects on liver function.
Diagnosis
Diagnosis focuses on measuring pressure in the portal vein and identifying related complications. Testing may include:
- Ultrasound or Doppler imaging: Detects blood flow changes and enlarged veins.
- CT or MRI: Evaluates the liver’s structure and connected blood vessels.
- Endoscopy: Screens for esophageal or gastric varices (enlarged veins prone to bleeding).
- Blood tests: Assess liver function and platelet counts.
All diagnostic studies can be performed on-site or through coordinated imaging and endoscopy services at The Medical Group of New Jersey.
Treatment
Treatment aims to lower pressure in the portal system and prevent serious complications such as variceal bleeding.
Medical Therapy
- Beta-blockers: Reduce portal pressure and the risk of bleeding.
- Diuretics: Manage fluid buildup and swelling.
- Antibiotics: Used in certain cases to prevent infection in ascitic fluid.
Procedural & Surgical Options
- Endoscopic band ligation: Treats or prevents bleeding from varices.
- TIPS (Transjugular Intrahepatic Portosystemic Shunt): Creates a new channel in the liver to reduce pressure and prevent recurrent bleeding or ascites.
- Liver transplantation: Considered for advanced liver disease or recurrent complications.
Ongoing Management & Prevention
Portal hypertension requires continuous monitoring to prevent life-threatening complications. Your hepatologist will recommend:
- Regular endoscopy to monitor for new or enlarging varices
- Ongoing medication review and dose adjustments
- Low-sodium diet to control fluid buildup
- Avoiding alcohol and non-prescribed medications that can harm the liver
- Routine imaging every 6–12 months to assess circulation and liver status
At The Medical Group of New Jersey, our hepatology team coordinates care with gastroenterology, radiology, and transplant specialists to ensure comprehensive management and long-term stability.
