Introduction: intrauterine demise occurs in 5% of all twin pregnanciesThe etiology is unknown in the majority of cases; however, twin-to-twin transfusion syndrome, Rh incompatibility, chromosomal and congenital abnormalities, preeclampsia, umbilical vein thrombosis, single umbilical artery, abnormalities arising from the location of placenta, and umbilical cord and uterine malformations are the main causes of fetal death in the rest of the casesSingle intrauterine demise may cause severe outcomes for the surviving fetus, especially in monochorionic twin pregnancies. Complications such as cerebral impairment, preterm labor and related sequelae, and subsequent death of the surviving fetus may occur in these cases. Aims and objectives: To report a case of MCDA twin gestation with intrauterine fetal demise of one twin at 25weeks 3 days and pregnancy continued till term Materials and methods: 24 year old G2P1L1 with 27 weeks 3 days with MCDA twin gestation with moderate anemia with previous vaginal delivery 4 years back came for antenatal checkup with scan report showing intrauterine fetal demise of one twin. She was started on Inj MgSO4 for neuroprotection and antenatal corticosteroids were also given and Inj Iron sucrose 500 mg in divided doses for anemia.Scan report showed Twin intrauterine gestation with Twin A live 25 weeks 1 day with normal Doppler parameters and twin B 16 weeks 5 days with no cardiac activity . Repeat scan after 1 week also done with Tein A live with normal Doppler parameters.Patient was monitored serially with USG and coagulation profile which was repeated every 3 days with no derangement.Fetal medicine opinion was sought and was advised to continue the pregnancy if the Doppler parameters are normal and advised serial monitoring.She was advised to come weekly for antenatal checkup. Results: She was then admitted at 35 weeks 2 days in early labor and Emergency CD done I/v/o twin B IUFD and extracted live male baby weighing 2040g and twin B fetus papyraceus.Placenta and membranes sent for HPE. Follow up done and Twin A has attained all milestones and has normal neurological development. Conclusion: Twin pregnancy itself comes with its set of complications.Single intrauterine fetal demise in MCDA twin gestation needs close monitoring and regular follow up and multidisciplinary approach for a favorable outcome of both the mother and fetus. Discussion: Although MCDA twin pregnancy with single intrauterine fetal demise has poor outcome, regular monitoring with serial USG and follow up pregnancy can be continued until the Doppler parameters are normal and coagulation profile of the mother is within normal limits.
