Modified cervix cerclage was applied to 75 women with placenta praevia, between the 16th and 36th weeks of pregnancy. Results obtained from conservative treatment of patients for placenta praevia are compared with those obtained from surgical treatment. Pregnancy was extended 38.4 days on average by cervix cerclage. Complaints were removed by surgery from 50.6 per cent of the patients who were dismissed from hospital. They showed neither bleeding nor any sings of imminent premature birth. Perinatal mortality went down to 6.45 per cent. Average extension of pregnancy by conservative treatment was 12.8 days. Only 7.3 per cent of the patients could be dismissed from hospital. Perinatal mortality went up to the order of 19.1 per cent. These data are interpreted as providing evidence to the advantage of surgical treatment of placenta praevia, as perinatal mortality is reduced.
对75例前置胎盘孕妇在妊娠16至36周期间实施改良宫颈环扎术。将前置胎盘患者保守治疗的结果与手术治疗的结果进行比较。宫颈环扎术使妊娠平均延长38.4天。手术消除了50.6%出院患者的不适症状。这些患者既无出血，也无即将早产的迹象。围产儿死亡率降至6.45%。保守治疗使妊娠平均延长12.8天。只有7.3%的患者可以出院。围产儿死亡率升至19.1%左右。这些数据被解释为表明前置胎盘手术治疗具有优势，因为围产儿死亡率降低了。
