‘Half-Match' Transplant Helps Teen with Sickle Cell Disease

Rhiannon Perry spent years in pain, suffering from strokes, seizures and hallucinations caused by sickle cell disease.

So her doctors at Children’s National Health System turned to a half match procedure, which offered a much longer list of potential donors. News4’s Aimee Cho reports on her progress and the hope for other patients.
