Thrombosis Blood Clots

A thrombosis is a blood clot that develops within veins or arteries in the body. Thrombosis can be serious, or sometimes just inconvenient. It often occurs as a complication of a procedure, medication or other disease. Left untreated, a thrombosis can cause long-term problems, such as chronic swelling, pain or even permanent damage to internal organs. Thrombosis in children is uncommon, and is most often seen in children with complex medical problems or procedures.

Thrombophilia refers to anything that increases a person’s tendency to develop blood clots. Thrombophilia can be considered the opposite of hemophilia, a disorder that prevents blood from clotting.

How Dana-Farber/Boston Children's approaches thrombosis

Children, teens and young adults with blood clots are treated through the Thrombosis and Anticoagulation Program at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. 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 can visit our outpatient center staffed by pediatric hematologists and pediatric hematology nurse practitioners who have specialized expertise in thrombosis.
