After months of preparation, a team at the Mayo Clinic in Rochester will attempt to separate a set of conjoined twins on Friday. Abbigail and Isabelle Carlsen were born in November 2005, joined at the chest and abdomen. The procedure will be complicated and could last 12 hours.
The Mayo Clinic has twice before separated conjoined twins. MPR's Cathy Wurzer talked with Dr. Christopher Moir, who was involved in both those cases. Dr. Moir will lead the surgery on Friday.
