Abstract

VILLAMIZAR-DURAN, Rocío et al. Pulmonary hypertension of the newborn with in utero closure of the ductus arteriosus and twin reversed arterial perfusion sequence. Rev. Colomb. Cardiol. [online]. 2017, vol.24, n.4, pp.410-410.  Epub Jan 17, 2017. ISSN 0120-5633.  http://dx.doi.org/10.1016/j.rccar.2016.11.007.

Introduction:

Pulmonary hypertension of the newborn secondary to in utero closure of the ductus arteriosus is a frequent complication in pregnant patients taking non-steroidal antiinflammatory drugs during pregnancy. We present a case of reversed arterial perfusion sequence in a twin pregnancy with evidence of survival of the acardiac twin with the blood flow of the pump twin. The treatment of choice is surgery with intrafetal laser coagulation on the acardiac twin, to prevent further complications on the healthy twin.

Clinical case:

Twin with reversed arterial perfusion sequence. At 22 weeks gestation intrafetal laser coagulation on the acardiac twin was performed. The mother received acetaminophen for two days and non-steroidal anti-inflammatory drugs for the management of pain. Fetal echocardiogram was conducted at 31 weeks gestation, evidencing diastolic dysfunction of the right ventricle and ductus arteriosus closure. She underwent an emergency c-section; the newborn had pulmonary hypertension during the neonatal period that was solved with medical management.

Conclusion:

Pulmonary hypertension of the newborn secondary to in utero closure of the ductus arteriosus due to drug consumption is an entity that poses a risk to the fetus, so a timely diagnosis and treatment is essential to improve survival of our patients.
