Intrafetal laser was successfully carried
out in all cases, but ultrasound examination within 2 weeks
of the procedure demonstrated that the co-twin had died in
11 cases and was alive in the other 11. In the dichorionic
group there was one miscarriage at 23 weeks due to cervical
incompetence and in the other 10 cases there were two live
births at a median gestational age of 35.0 (range 32.2–37.1)
weeks. In the 11 cases where both monochorionic fetuses
died the separate triplet was live born at a median gestation
of 38.0 (range 32.2–40.5) weeks.
