Complications

By Mayo Clinic staff

Most conjoined twins die in the womb (stillborn) or soon after birth.

Vaginal delivery is rarely possible for conjoined twins. About 40 percent of conjoined twins are stillborn. Of conjoined twins born alive, less than half survive long enough to be candidates for separation surgery.
