Michael Wagner can only donate liver to save 1 twin daughter

A Kingston, Ont., man is set to donate part of his liver to save one of his twin girls, but cannot donate to both.

Michael and Johanne Wagner's three-year-old girls Binh and Phuoc have Alagille syndrome, which affects the function of their livers. The couple adopted the Vietnamesetwins when they were 18 months old. They have seven other children.

Doctors say both need transplants to survive, but the girls'mother said their father is the only match that has been found sofar.

Johanne Wagner said surgeons at Toronto General Hospital are setto operate on Michael and one daughter in about two weeks.

They cannot bear to choose, so doctors will decide based on thebest candidate.

The Wagners are still hoping to find a donor for their other daughter,who will die if she doesn't get a new liver. The couple has a Facebook page and a blog calledOne More Potato in the Pot with more information about the twins.

Donors must be between 18 and 55 years old with A or O blood type. Volunteer donors are asked to contact the University Health Network in Toronto.
