I80-I89: Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified
I81: Portal vein thrombosis
The liver is an important organ on the top right of the abdomen. For example, it helps with blood clotting and detoxifying the body. Nutrients from food are processed in the liver. A large vein collects the nutrient-rich blood from the gastrointestinal area and carries the blood to the liver. In your case, this large vein has been blocked by blood clotting.
Different reasons can cause blood clots to form. For example, if the liver hardens, the blood is unable to flow into the liver properly. As a result, blood clots can form more easily in the large vein. Some people are prone to blood clots. This is then congenital or caused by another disorder.
If the large vein gets blocked, it can cause abdominal problems. If the large vein is constantly narrowed, the blood is unable to flow properly from the gastrointestinal area. The blood then does not flow through the liver, but through other veins to the heart. This can cause the veins in the oesophagus or the stomach to get wider, for example, because more blood is then flowing through those veins.
