Family searching for organ donor to save twin girls' lives

A family may soon have to make a heart-wrenching choice that could determine which of his twin daughters gets to keep living.

In 2012, Michael and Johanne Wagner adopted 18-month-old Vietnamese twins, Binh and Phuoc. The couple knew the twins had health problems, but they wanted to help.

Today, the 3-year-old girls are battling Alagille syndrome, a genetic disorder that affects liver function.

"They're in end-stage liver disease. The clock is ticking. If they don't get an organ, they're going to die," Johanne Wagner told CBC News.

Michael is a match and can donate liver tissue, but he only has enough to save one of his daughters' lives. Now, they are desperately searching for another compatible donor before it becomes too late.

If a donor isn't found, the Wagners will be left with choice. The couple says they can't choose between their daughters, so they'll let doctors decide which daughter gets Michael's life-saving transplant.

The prospective donor must be between the ages of 18 and 55 and have type A or type O blood. The couple has outlined what the process would look like for a donor and how you can help in this blog post.

The family plans to keep fighting to save both girls' lives until the very end.

"It was what we promised from the beginning when we picked them up from Vietnam. We promised we would do everything in our power to make everything OK, and this is just keeping that promise," Michael Wagner told CBC News.
