Portal vein thrombosis
Portal vein thrombosis (PVT) is a medical condition that involves the formation of a blood clot in the portal vein, which carries blood from the digestive organs to the liver. The pronunciation of the term is /ˈpɔːrtəl veɪn θrɒmbəʊsɪs/.
Etymology
The term "portal vein thrombosis" is derived from three words. "Portal" comes from the Latin word "porta," which means gate. This is in reference to the function of the portal vein as a gateway for blood from the digestive organs to the liver. "Vein" comes from the Latin word "vena," which means blood vessel. "Thrombosis" comes from the Greek word "thrombos," which means clot.
Symptoms
Symptoms of portal vein thrombosis may include abdominal pain, nausea, vomiting, and jaundice. In severe cases, it can lead to liver failure and death.
Causes
Portal vein thrombosis can be caused by several factors, including liver cirrhosis, pancreatitis, infection, and cancer. It can also occur as a complication of surgery.
Diagnosis
Diagnosis of portal vein thrombosis is typically made through imaging studies, such as ultrasound, CT scan, or MRI. Blood tests may also be used to assess liver function and check for signs of clotting.
Treatment
Treatment for portal vein thrombosis may include anticoagulant therapy, to prevent further clotting, and thrombolytic therapy, to dissolve the existing clot. In severe cases, surgery may be required.
