title: Genetic amniocentesis following multifetal pregnancy reduction to twins: assessing the risk.
abstract: Fifty-three patients who elected to reduce their pregnancies to a twin gestation in our centre are known to have subsequently undergone genetic amniocentesis. Five of these patients lost entire pregnancy following the genetic amniocentesis procedure. This is equivalent to a 9.4 per cent pregnancy loss rate for reduced twin gestations in comparison with an expected loss rate of 2 per cent for non-reduced twin gestations.
