In this comparative review of retained and unretained second twins, the commonest causes of retention of the second twins, were found to be uterine inertia (48.4%) and obstruction from malpresentation and malposition (32.3%). The pair-presentation most likely to be retained was vertex/transverse. Apgar scores were lower for retained than unretained second twins. The perinatal mortality rate was significantly higher for the retained second twins (258/1000) compared to the unretained second twins (60.2/1000) (P < 0.002). Early recognition of twin pregnancies in which the 2nd twin is more likely to be retained, and prompt application of appropriate remedial measures would reduce the incidence of retention of the second twin.
在这项对留存和未留存的第二胎儿的比较性综述中，发现第二胎儿留存的最常见原因是子宫收缩乏力（48.4%）以及胎位不正和位置异常导致的梗阻（32.3%）。最有可能留存的胎位组合是头位/横位。留存的第二胎儿的阿氏评分低于未留存的第二胎儿。留存的第二胎儿的围产期死亡率（258/1000）显著高于未留存的第二胎儿（60.2/1000）（P<0.002）。早期识别第二胎儿更有可能留存的双胎妊娠，并及时采取适当的补救措施，将降低第二胎儿留存的发生率。
