Dad performs a life-saving transplant on his daughter to save her.

PITTSBURGH (KDKA) — A St. Louis father provided a life-saving liver transplant for his 15-month-old daughter at UPMC Children’s Hospital.

It’s been a long road in the short life of Autumn Pillman.

The 15-month-old was born with a rare liver disease called biliary atresia.

It’s a blockage of the bile ducts and can lead to cirrhosis of the liver, which is deadly if it goes untreated.

Pillman was diagnosed with the disease at 9 weeks old.

She had her first surgery a week later, and not long after that, she was put on the transplant list.
