S35: Injury of blood vessels at abdomen, lower back and pelvis level

S35.3: Injury of portal or splenic vein

There are many blood vessels in the abdomen. For example, there are blood vessels for the digestive organs, but also for the skin and muscles.

Veins are blood vessels that transport the blood back to the heart. The portal vein collects nutrient-rich blood from the abdominal organs and carries it to the liver. The blood from the splenic vein flows straight into the portal vein. You have an injury to an portal vein or splenic vein. You may also have damaged one or more veins with blood from the intestine.

When a blood vessel is damaged, there is usually bleeding. If the bleeding is heavy, blood may collect in the tissue. There may then be some pain. When there is bleeding below the skin, a bruise sometimes forms.
