A 10-year-old girl from Pennsylvania suffering from cystic fibrosis underwent the lung transplant. But within hours her lungs transplant surgery got failed.

She required new sets of lungs as otherwise she would not have survived. Janet Murnaghan, Sarah's father, was of the view that Sarah underwent the surgery at Children's Hospital of Philadelphia. She was then put in the adult lung transplant list.

Sarah's parents had to take the help of court and they get permission to receive adult set of lungs. Second surgery of lungs transplant took three days after the first surgery. Though her surgery has remained successful, the case has become quite controversial.

Experts were of the view that patients diagnosed with cystic fibrosis are able to live up to 40 years. But such was not the case with Sarah and she was not able to live for few more weeks if lung transplant would not have been done.

Sarah has been improving with passage of time, said Murnaghan. It seems that her issue has become a reason of debate among experts. Experts affirmed that basis on which one should be allocated organs is complex as it is about giving someone second chance of life.
