Summary A rare case is reported of twin-reversed arterial perfusion (TRAP) sequence in a triplet pregnancy, fetal intervention in the first trimester and pregnancy outcome. We report a case of TRAP sequence complication in dichorionic triamniotic triplet pregnancy, with a normally developing fetus and an acardiac fetus connected via arterio-arterial anastomoses in a monochorionic diamniotic twin pair and a separate fetus. TRAP sequence was diagnosed at 13 weeks in triplet pregnancy after in vitro fertilization (IVF) and embryo transfer of two blastocysts. Color Doppler assessment showed persistent arterial flow in the acardiac twin. Intrafetal laser coagulation was carried out at the time of the diagnosis, and the pregnancy outcome was two survivals at 36.4 weeks of gestation.
