Portal vein thrombosis happens when a blood clot blocks normal blood flow through the portal vein, the vessel that carries blood from the digestive organs to the liver. This blockage impairs the liver's ability to filter blood properly and, if not treated, can lead to complications such as portal hypertension or gastrointestinal bleeding.
Early on, symptoms may be mild or absent. As PVT progresses, you may notice:
Several factors can increase the risk of clot formation in the portal vein:

Portal vein thrombosis is most often caused by liver disease (such as cirrhosis), inherited or acquired clotting disorders, tumors (especially liver cancer), abdominal infections or inflammation, recent surgery or injury, and other chronic illnesses that affect blood flow through the portal vein.
Chronic portal vein thrombosis is managed with long-term anticoagulants to prevent new clots, regular imaging (CT scans or Doppler ultrasound) to monitor blood flow, dietary adjustments to support liver health, and treatment of any underlying liver or clotting disorders.
A CT scan is often necessary if you have symptoms or risk factors for portal vein thrombosis. It provides detailed images that confirm the presence, location, and extent of the clot, guiding further treatment.
While no diet can completely prevent clots, a balanced, nutrient-rich diet-high in lean protein, fruits, vegetables, and whole grains-supports liver function and overall vascular health, reducing additional risks.
Portal vein thrombosis can become life-threatening if left untreated, leading to complications like intestinal ischemia or severe liver dysfunction. Early diagnosis and treatment significantly lower these risks.
Many patients begin to feel improvement within days of starting anticoagulants, but full treatment typically continues for several months and sometimes longer, depending on clot size, underlying causes, and response to therapy.
Tumor thrombosis occurs when a cancerous growth-most often a liver tumor-invades or compresses the portal vein, causing a blood clot. This requires both anticoagulation and targeted cancer therapy.
Yes. In select cases, procedures such as a thrombectomy (removal of the clot) or a TIPS (transjugular intrahepatic portosystemic shunt) may be recommended to restore blood flow and relieve portal hypertension.
Follow-up typically begins on a monthly basis to monitor anticoagulation levels and symptom relief, then extends to every few months for ongoing imaging and blood tests to ensure long-term stability.
Although rare in children, portal vein thrombosis can occur, often due to abdominal infections, congenital clotting disorders, or neonatal umbilical vein catheterization. Pediatric specialists tailor diagnosis and treatment plans accordingly.
