The survival rate of babies with sail placenta cannot be said to be very low, but there will be a certain risk, the impact is not very large, the survival rate is about 60%-80%. For modern medicine, it is possible to produce by technical means, but there is no guarantee that the child born will have congenital diseases. It is recommended that the patient go to the hospital for timely medical attention, and then take a film for analysis, so that you can consider whether you want to have a caesarean section, which can reduce the risk of production. It also depends on whether there is preterm labor, if there is also early hospitalization, it does not affect the child much, as long as the anterior vessels on the placenta are not ruptured, there will be no effect on the child, there are exceptions during pregnancy, go to the hospital for regular maternity checkups. If you feel abdominal pain or chest tightness you need to find a doctor and explain the situation, as long as the early intervention for the subsequent birth only will be helpful.
