Five-month-old conjoined twins Abygail and Madysen Fitterer, of Bismarck, N.D., will undergo separation surgery at the Mayo Clinic on Wednesday, the clinic announced Tuesday.
The girls are joined at the chest and share their front chest wall. In October, doctors implanted tissue expanders to stretch the girls' skin enough to close their incisions from the separation surgery.
"Abygail and Madysen have been growing in strength and size and character for weeks now," according to a Mayo video news release.
The surgical team will be led by Dr. Christopher Moir, who also led the teams that separated conjoined twin girls from Fargo, N.D., in May and twin boys from Mankato in November.
