Emergency cerclage Archives - Revista Brasileira de Ginecologia e Obstetrícia

In pregnant women with cervical incompetence in whom there is also dilatation of the cervix and prolapsed membranes there are technical difficulties in performing cerclage in order to prolongate pregnancy until sufficient fetal maturity assures survival of the newborn. We describe a case of cervical incompetence with prolapsed membranes at 21 weeks of gestation, in which we caused the decrease of intrauterine pressure with drainage of amniotic fluid by amniocentesis, until reintroduction of membranes into the uterine cavity was possible. This procedure allowed traction of cervical lips and cerclage with less mechanical trauma, warranting the evolution of pregnancy for 12 weeks and fetal survival
