Delivery of a severely anaemic fetus after partial molar pregnancy: clinical and ultrasonographic findings

The incidence of a normal live fetus and a partial molar placenta is extrem ely rare. Although triploidy is the most frequent association, a fetus with normal karyotype can survive in cases of partial molar pregnancy. We repor t a case of partial molar placenta in which a live female baby was delivere d at 32 weeks gestation by a 30-year-old woman. At the 18th week, ultrasono graphic examination revealed a normal fetus with a huge, multicystic placen ta, Chromosomal evaluation by amniocentesis revealed a normal female karyot ype (46,XX), and serial biometric measurement of the fetus showed normal gr owth during pregnancy. There were no obstetric complications until the 32nd gestational week when preterm rupture of the membranes occurred. The elect ronic fetal heart beat tracing showed a repeated sinusoid pattern and late deceleration after admission. The patient underwent emergency Caesarean sec tion and delivered a 1551-g, anaemic female baby with an Apgar score of 1, 4 and 6 at 1, 5 and 10 min, respectively. The baby recovered within 2 weeks after respiratory support and transfusion of packed red blood cells. Altho ugh anaemia is one of the risk factors that. jeopardize the fetus in the ca se of partial molar pregnancy, termination is not indicated when the fetus is normal and no complications have occurred.
