Persistent absence of umbilical blood flow at 17 weeks’ gestation may be due to changes in condition caused by cord compression, placental malfunction, fetal malformation, etc. Depending on the condition, observation and treatment can be carried out or appropriate treatment plan can be chosen to terminate the pregnancy.
1. Umbilical cord compression: In the 17th week of pregnancy, if the umbilical cord is wrapped around the neck, it may cause persistent absence of umbilical blood flow. If the fetal movement and heart rate are normal and growth and development are good, it can be treated with observation and regular pregnancy checkups. If the fetus is suffering from intrauterine hypoxia, it can be treated with oxygen intake.
2. Placental dysfunction: At 17 weeks of pregnancy, if the pregnant woman has placental dysfunction, it may cause persistent absence of umbilical blood flow. Induction of labor may be necessary to terminate the pregnancy.
3. Fetal malformation: If the fetus at 17 weeks’ gestation develops serious malformation, it may cause persistent absence of umbilical cord blood flow, and induction of labor may be necessary to avoid the birth of a malformed child.
The causes of persistent absence of umbilical cord blood flow at 17 weeks of pregnancy are more varied and need to be treated with appropriate treatment options under the guidance of obstetricians and gynecologists.
