This case report demonstrates the use of ultrasound and doppler flow in the management of mono-amniotic monochorionic (M/M) twins. M/M twinning is a rare but significant event. It is associated with high rates of fetal mortality, most commonly cited at anywhere from between 30% and 70%. A common cause of death is cord entanglement. The case presented is that of a 19-year-old gravida 1 at 30 weeks with M/M twins in which multiple cord knots were found by ultrasound color doppler flow after variable fetal heart rate decelerations occurred. This prompted a decision for immediate cesarean delivery with normal fetal outcomes. Improvements in perinatal imaging systems are therefore beneficial in the management of M/M twins.
本病例报告展示了超声和多普勒血流技术在单绒毛膜单羊膜囊（M/M）双胎管理中的应用。M/M双胎妊娠是一种罕见但重要的情况。它与高胎儿死亡率相关，最常引用的死亡率在30%至70%之间。常见的死亡原因是脐带缠绕。该病例为一名19岁初产妇，孕30周，怀有M/M双胎，在出现可变减速的胎儿心率后，经超声彩色多普勒血流发现多个脐带结。这促使决定立即剖宫产，胎儿结局正常。因此，围产期成像系统的改进对M/M双胎的管理有益。
