An 11-year-old Pennsylvania girl whose need for new lungs sparked a national debate on how donor organs are prioritized is back at home after six months in the hospital.

A family spokeswoman says Sarah Murnaghan was discharged Tuesday from The Children's Hospital of Philadelphia. She later was carried into her family's Newtown Square home, where the entrance was festooned with balloons and bore a big sign saying "Welcome Home, Sarah!"

Sarah received two sets of lungs this summer as she struggles with the effects of end-stage cystic fibrosis. The operations came after a federal judge intervened in her parents' lawsuit challenging national transplant rules that put her at the end of the waiting list for adult lungs.
