Stillbirth in dichorionic twins discordant for major and minor anomaly, followed by asynchronous delivery - a rare...

The single stillbirth long-term intrauterine retention in dichorionic twin pregnancy is rarely reported. Also, the birth of a fetus is followed in most cases by immediate expulsion of the second twin. We hereby present an unusual case of asynchronous delivery of dichorionic twins, associating discordance for major and minor anomaly. The intrauterine death of the twin A, presenting a large sacrococcygeal tumor, occurred in the second trimester. The deceased twin A was born at 29 weeks' gestational age (GA). The twin B was extracted by Caesarean section at 31 weeks and had a good outcome. We performed a close follow-up of the high-risk pregnancy and we used tocolytic and antibiotic drugs for prolonging it. Corticoid therapy was administered for the lung maturation of the second twin. The expectant management in the single twin stillbirth dichorionic pregnancy and the asynchronous delivery had a significant impact on the newborn outcome.
