Our expertise gives your child the best chance to reclaim a healthy, happy childhood. We help children with blood disorders enjoy active lives with fewer bleeding episodes.

What Are Hemostasis and Thrombosis?

The Hemostasis and Thrombosis Center at CHLA helps children who have:

  • Hemostasis disorders: Bleeding disorders that occur when proteins in the blood that promote clotting are either missing or don’t function properly.
  • Thrombosis: Clotting disorders caused when a clot blocks a blood vessel. Children typically develop clots as a complication of another medical condition or treatment.

Hemostasis and Thrombosis Research and Innovation

Research at CHLA is setting the foundation for new bleeding and clotting disorder treatments. We’ve helped develop medications that have nearly eliminated symptoms in some children with hemophilia A. The treatment also relieved joint issues, enabling children who had depended on wheelchairs to walk independently for the first time in years.
