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.
