“Umbilical cord”, homophonic “expectation”, is the bond between mother and child, and it is a high-speed channel to maintain the exchange of material between mother and child, but Huihui (pseudonym), a 24-year-old pregnant mother, encountered a morbidity For 4 to 8 in 10,000 sail-like placenta + blood vessels previa, the situation is very dangerous. Fortunately, the abnormality was found in time during the ultrasound examination at Hainan Modern Women and Children’s Hospital. Under the protection of the obstetrics medical staff, Huihui survived a thrilling pregnancy and gave birth to a 5.9-pound baby safely.
01
Ultrasound detected abnormality during pregnancy
Pregnancy At 22 weeks, Huihui came to Hainan Modern Women’s and Children’s Hospital for an ultrasound examination, and the sonographer found a serious problem. Under normal circumstances, the umbilical cord is attached to the placenta, but Huihui is a sail-shaped placenta. The umbilical cord is attached to the fetal membrane outside the placenta, causing the blood vessels of the umbilical cord to be scattered into several branches, in a fan-shaped distribution. But this is not the most terrifying. Under the strict inspection of the sonographer, it was also found that the blood vessel branch of Huihui’s umbilical cord crossed the internal cervical orifice and entered the placental parenchyma! This is medically called vascular previa, and the fetal mortality rate can be as high as 70% – 100% when the vascular previa ruptures.
“Vaili placenta is an uncommon umbilical cord attachment abnormality, but it is highly Serious complications, in the process of uterine contractions or production, the blood vessels are easily ruptured due to factors such as traction. Once the rupture of the fetal membranes causes the umbilical blood vessels to tear and bleed, there will be a large amount of bleeding in a short period of time, and in severe cases, it will be very fast. Death. Ultrasound is a better method for prenatal diagnosis of abnormal umbilical cord vascular insertion and pre-vascularization.” Gao Yun, director of the Ultrasound Department, said bluntly.

Obstetric care and care all the way to protect safety
The accurate diagnosis of B-ultrasound provides a strong guarantee for clinical guidance of obstetrics. According to Huihui’s situation, Professor Xu Yan, vice president of Hainan Modern Women’s and Children’s Hospital, explained the situation to Huihui in detail, and said that this situation is more dangerous. At the same time, he comforted and encouraged Huihui, and repeatedly told her to take more rest, pay attention to uterine contractions and fetal movement, and regularly review ultrasound. “If it’s just a simple veliform placenta, most pregnant women can have a vaginal delivery with close follow-up throughout the pregnancy. However, vaginal delivery is not recommended for pregnant women with a vascular placenta previa, and a comprehensive evaluation according to the situation is best at 34-36 weeks of pregnancy. caesarean section delivery.” Professor Xu Yan said.
Huihui’s condition has attracted the attention of obstetricians and sonographers. With the help of the obstetrician and sonographer, Huihui successfully reached 36 weeks of pregnancy. After a comprehensive evaluation, it was decided to terminate the pregnancy for Huihui. The cesarean section operation was performed by Professor Xu Yan, with the cooperation of Xiao Shu, the deputy chief physician of the obstetrics department. Huihui successfully gave birth to a baby weighing 5.9 catties. The mother and daughter were safe, and everyone was finally relieved.

Ultrasound screening before 28 weeks of pregnancy can improve the detection rate
According to Gao Yun, director of the Ultrasound Department of Hainan Modern Women and Children’s Hospital, Hainan Modern Women and Children A total of 384 cases of abnormal umbilical cord placenta were detected by ultrasound in the hospital in 2021. Among them, 6 cases of sail-shaped placenta combined with vascular previa were detected before 28 weeks of gestation, which provided timely support for the clinical diagnosis of obstetrics. Director Gao Yun suggested that puerperae should have prenatal ultrasound examination on time and systematically assess the placental umbilical cord attachment, which is of great significance in reducing adverse pregnancy outcomes.
With the continuous development and wide application of ultrasound technology, the ultrasound department of Hainan Modern Women’s and Children’s Hospital can not only carry out obstetric fetal malformations In addition to screening and maternal and child heart screening, screening for obstetric scar uteroplacental accreta scoring, velicular placenta and vascular previa, placenta accreta scoring, marginal umbilical cord insertion, and umbilical cord prolapse can also be carried out. Provide support for obstetric clinical diagnosis, avoid risks, and escort mother and baby.
