Thrombosis is the process of forming a blood clot in a blood vessel. Most of the time, clotting is a normal, healthy process that stops bleeding.

Blood contains cell fragments called platelets. Platelets, in combination with blood clotting proteins, stick to wounds in blood vessels and to each other to help form clots, or plugs, where damage occurs. Sometimes clotting in blood vessels can be harmful. Health problems that relate to clots include thrombophilia, pulmonary embolism, deep vein thrombosis and peripheral arterial disease.

Children and teens with clotting problems are treated at Seattle Children’s, a founding organization of Seattle Cancer Care Alliance. Seattle Children’s has a long history of successfully caring for children and teens with blood disorders.

Expert Care for Your Child

Clotting problems in children and teens are not very common, so community doctors usually have limited knowledge about how to treat them. This is why in the United States almost all children with blood clots or related problems receive treatment at centers, like Seattle Children’s, that have special experience in children’s blood disorders.

Seattle Children’s Cancer and Blood Disorders Center brings together experts from more than 20 subspecialties to provide diagnostic services and treatments, including the very latest options. We consult with our pediatric interventional radiologists on using catheters to open affected blood vessels or to deliver clot-dissolving medications directly to the clot. With our pediatric pharmacists, we are developing a special service to make anticoagulation treatment safer and more convenient, both for children who visit our clinic and those who are in the hospital.

Our team of pediatric hematologists, nurse practitioners, physician assistants, nurses, Child Life specialists, social workers, and chaplains partner with you to provide expert, family-centered care and compassionate support. We help you understand your child's health and treatment options because you, your child, and your family are an important part of the care team.

Because Seattle Children’s doctors take part in national and international research studies, and often lead them, we can offer new treatment options that many other hospitals cannot give their patients.
