Received Date: December 28, 2019; Published Date: March 15, 2019
Background: Anencephaly is a lethal diagnosis. In twin pregnancies discordant for anencephaly, there are risks of development of polyhydramnios, severe preterm delivery and death of an encephalic fetus.
Case presentation: A 30-year-old G 111 Para 11 both were vaginal delivery presented at Ian Donald ultrasound department for first time scan at 27-week gestational age. Ultrasound showed a live dichorionic, diamniotic intrauterine twin pregnancy. The Gestational age was 27 weeks and 5 days. A cranium of twin A was described. Polyhydramnios was noted for twin B at 29+5 weeks. After adequate obstetric, genetic counseling and given all the information about the risks involving this pregnancy, the parents opted for conservative management without any intervention.
Conclusion: The early diagnosis of anencephaly before 16 weeks’ gestational age in the twin decrease morbidity and mortality to the unaffected normal twin by providing the option of selective fetal reduction at an optimal gestational age.
