Abstract

Aim

To clarify the current situation and outcomes of vasa previa (VP) in Japan.

Methods

A questionnaire survey on VP was conducted at all 408 perinatal centers in Japan. The content of the survey included (1) the management strategy for pregnant women who were diagnosed with VP and (2) the number and outcomes of VP cases managed between January 2020 and December 2022.

Results

Questionnaires were collected from 220 (53.9%: 220/408) perinatal centers. (1) A total of 78.8% (164/208) of facilities implemented routine hospitalization. Routine hospitalization was initiated at 32 (22–36) [median (range)] weeks of gestation. The timing of planned cesarean section (CS) was at 36 (33.5–39) weeks of gestation in 198 facilities. (2) Of the 220 facilities that responded, 109 (49.5%: 109/220) accommodated patients with VP during the observation period. The total number of VP cases was 351, with a frequency of one case (0–33) per single perinatal center for 3 years. Emergency CS was required in 89 cases (25.4%: 89/351). There were no fetal or neonatal deaths in this study. The number of undiagnosed patients with VP prenatally was seven (2.0%: 7/351). Umbilical vessel rupture occurred in two cases (0.6%: 2/351).

Conclusions

Current management strategies in Japanese perinatal centers that responded to this survey appear to yield good perinatal outcomes in VP. Additional studies and comparisons are needed to elucidate the necessity of routine hospitalization, the optimal duration of hospitalization, and the timing of planned CS.

围产中心处理前置胎盘的策略和经验:日本全国调查。
目的:明确日本前置胎盘(VP)的现状和结果:在日本所有 408 家围产中心开展了一项关于前置胎盘的问卷调查。调查内容包括:(1)确诊为前置胎盘孕妇的处理策略;(2)2020 年 1 月至 2022 年 12 月期间处理的前置胎盘病例数量和结果:从 220 家(53.9%:220/408)围产中心收集了调查问卷。(1)共有 78.8%(164/208)的机构实施了常规住院治疗。常规住院治疗开始于妊娠 32(22-36)周[中位数(范围)]。在 198 家医疗机构中,计划剖宫产(CS)的时间为孕 36(33.5-39)周。(2)在做出回复的 220 家医疗机构中,有 109 家(49.5%:109/220)在观察期内收治了 VP 患者。VP 病例总数为 351 例,3 年中每个围产中心发生 1 例(0-33 例)。89例患者(25.4%:89/351)需要进行急诊手术。本研究中没有胎儿或新生儿死亡病例。产前未确诊的 VP 患者有 7 例(2.0%:7/351)。脐带血管破裂有两例(0.6%:2/351):结论:参与此次调查的日本围产中心目前的管理策略似乎能为 VP 患者带来良好的围产期预后。需要进行更多的研究和比较,以阐明常规住院治疗的必要性、最佳住院时间以及计划 CS 的时机。
