Sail-like placenta has the risk of causing intrauterine hypoxia and other conditions, and requires intensive maternal and fetal monitoring and immediate intervention if necessary. Sail-like placenta is a relatively uncommon clinical condition caused by abnormal attachment of the umbilical cord. Sail-like placenta has a certain risk of causing fetal growth restriction, intrauterine hypoxia, and other complications, and therefore requires thorough prenatal testing. In the case of placenta previa, it is important to monitor the condition of the fetus. On the one hand, it is necessary to pay attention to whether there is any discomfort, such as vaginal bleeding, and changes in uterine height and abdominal circumference; on the other hand, it is recommended that ultrasound examinations be performed regularly to monitor the fetal heart and fetal growth. Since the placenta previa is prone to hemorrhage, hospitalization is recommended as soon as symptoms of labor appear. If the examination reveals abnormal fetal heartbeat, anterior vessels, or other conditions that are not suitable for a normal delivery, a cesarean section is recommended. It is advisable to consult a hospital promptly when placenta previa develops, and to follow the doctor’s instructions for regular checkups.
