An omphalopagus parasitic twin after intracytoplasmic sperm injection

Objective: To describe a first case of parasitic twin achieved after intracytoplasmic sperm injection (ICSI). Design: Case report. Setting: Perinatal center at a Japanese university hospital. Patient(s): A 30-year-old pregnant Japanese woman with a history of secondary infertility achieved after ICSI was diagnosed with an omphalopagus parasitic twin pregnancy by prenatal ultrasound at 28 weeks of gestation. Intervention(s): A female infant was delivered by scheduled cesarean section at 30 weeks of gestation. The cesarean section was performed for dystocia. Main Outcome Measure(s): Brief review of parasitic twin and malformations in fetuses achieved after ICSI. Result(s): Resuscitation was not done because of the poor prognosis for both fetuses. Molecular analysis with informative genetic markers is consistent with monozygotic pregnancy. Conclusion(s): A careful ultrasound examination is indicated to detect additional anomalous findings in twin fetuses achieved after ICSI. (C)2004 by American Society for Reproductive Medicine.
