Also known as: Consumption coagulopathy and DIC
- Blood transfusion reaction
- Cancer, especially certain types of leukemia
- Inflammation of the pancreas (pancreatitis)
- Infection in the blood, especially by bacteria or fungus
- Liver disease
- Pregnancy complications (such as placenta that is left behind after delivery)
- Recent surgery or anesthesia
- Severe tissue injury (as in burns and head injury)
- Large hemangioma (a blood vessel that is not formed properly)
- Bleeding, from many sites in the body
- Blood clots
- Drop in blood pressure
- Plasma transfusions to replace blood clotting factors if a large amount of bleeding is occurring.
- Blood thinner medicine (heparin) to prevent blood clotting if a large amount of clotting is occurring.
- Lack of blood flow to the arms, legs, or vital organs
Disseminated intravascular coagulation is a serious disorder in which the proteins that control blood clotting become overactive.
When you are injured, proteins in the blood that form blood clots travel to the injury site to help stop bleeding. If these proteins become abnormally active throughout the body, you could develop disseminated intravascular coagulation (DIC). The underlying cause is usually due to inflammation, infection, or cancer.
In some cases of DIC, small blood clots form in the blood vessels. Some of these clots can clog the vessels and cut off the normal blood supply to organs such as the liver, brain, or kidneys. Lack of blood flow can damage and cause major injury to the organs.
In other cases of DIC, the clotting proteins in your blood are consumed. When this happens, you may have a high risk of serious bleeding, even from a minor injury or without injury. You may also have bleeding that starts spontaneously (on its own). The disease can also cause your healthy red blood cells to fragment and break up when they travel through the small vessels that are filled with clots.
Risk factors for DIC include:
Symptoms of DIC may include any of the following:
Exams and Tests
You may have any of the following tests:
There is no specific treatment for DIC. The goal is to determine and treat the underlying cause of DIC.
Supportive treatments may include:
Outcome depends on what is causing the disorder. DIC can be life threatening.
Complications from DIC may include:
When to Contact a Medical Professional
Go to the emergency room or call 911 if you have bleeding that does not stop.
Get prompt treatment for conditions known to bring on this disorder.
