Cervical cerclage as a temporizing measure for the treatment of patients with placenta previa was evaluated in 25 patients admitted to the hospital for vaginal bleeding between 24-30 weeks' gestation and sonographic evidence of a placenta previa. The patients were randomly assigned to either cerclage (13) or conventional management (12). Cerclage patients had significantly better perinatal outcome, as indicated by more advanced gestational age at the time of delivery (34.9 +/- 3.0 versus 31.6 +/- 2.9 weeks; P = .02), larger birth weight (2709 +/- 511 versus 1812 +/- 506 g; P = .002), and fewer neonatal complications (two of 13 versus ten of 12 infants; P = .001). Maternal bleeding was more frequent and severe for patients in the control group. The total hospital cost was less for cerclage patients than for those receiving conventional expectant management ($9898 +/- 3943 versus $27,271 +/- 9901; P = .02). These results support the use of cervical cerclage for the treatment of patients with symptomatic placenta previa early in gestation.
对25例妊娠24 - 30周因阴道出血入院且超声检查证实为前置胎盘的患者，评估了宫颈环扎术作为一种临时治疗措施的效果。这些患者被随机分为环扎组（13例）和传统治疗组（12例）。环扎组患者围产期结局明显更好，表现为分娩时孕周更大（34.9±3.0周对31.6±2.9周；P = 0.02）、出生体重更大（2709±511克对1812±506克；P = 0.002）以及新生儿并发症更少（13例中有2例对12例中有10例；P = 0.001）。对照组患者的母体出血更频繁且更严重。环扎组患者的总住院费用低于接受传统期待治疗的患者（9898±3943美元对27271±9901美元；P = 0.02）。这些结果支持在妊娠早期对有症状的前置胎盘患者使用宫颈环扎术进行治疗。
