What is thrombosis?

A thrombosis is a blood clot that develops within veins or sometimes arteries in the body. Thrombosis may be serious or inconvenient but often occurs as a complication of a procedure, medication, or other disease. If left untreated a thrombosis can cause long-term problems; such as chronic swelling, pain, or even permanent damage to internal organs.

Thrombophilia refers to anything that increases one’s tendency to develop blood clots. Thrombosis in children is uncommon and is most often seen in children with complex medical problems or procedures. Thrombophilia can be considered the opposite of hemophilia, a disorder that prevents blood from clotting.

Thrombosis Treatment at Dana-Farber/Boston Children's

Children and young adults with blood clots are treated through the Dana-Farber/Boston Children’s Thrombosis and Anticoagulation Program. Through our unique program, we can quickly identify children who need anticoagulation medications (or “blood-thinners”) using established monitoring and risk identification guidelines. Children outside of the hospital visit our outpatient center staffed by pediatric hematologists and pediatric hematology nurse practitioners with specialized expertise in the diagnosis and treatment of thrombosis.
