概要 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 cen-
ters. (1) A total of 78.8% (164/208) of facilities implemented routine hospitaliza-
tion. 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 ves-
sel 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.
