Thrombosis Program
As the Hemostasis and Thrombosis Center Medical Director, Dr. Leslie Raffini leads the Thrombosis Program. Through clinical research, patient care, physician and provider education, and program development, the Thrombosis Program has become one of the nation’s premier programs for safe and effective management of anticoagulation (use of blood thinners), thromboprophylaxis (prevention of blood clots), and general hematologic care.
The thrombosis team is dedicated to providing accurate diagnosis, appropriate testing and imaging studies, and expert treatment to prevent or treat blood clots in children and adolescents, with a strong emphasis on safety and monitoring.
The team offers comprehensive patient and family education and support, physical therapy, assists with access to care, identifying barriers to care and helps develop strategies to overcome such barriers, and helps in communication and advocacy with schools, employers and insurance companies.
