No definite prenatal diagnosis could be made in any of them. After experiencing two cases, every risk case needed awareness especially in unexplainable severe fetal distress after small bloody aminotic fluid. However, two more fetal deaths occurred with Ruptured Vasa Previa. Antenatal diagnosis and elective cesarean section may reduce mortality and morbidity. The purpose of this report was to postulate whether some special devices may soon be able to detect this abnormality in a high index of suspicious cases.en-USChiang Mai Medical JournalCase Reports
