Scar pregnancy mainly refers to abnormal pregnancy in which women who have had a cesarean section experience excessive vaginal bleeding and late stage uterine rupture when they become pregnant again. Today, let's first understand the main symptoms of scar pregnancy.
Symptoms of Scar Pregnancy
Pregnant women with scar pregnancy generally do not have obvious discomfort symptoms in the very early stages of pregnancy.
The clinical manifestations at 5-16 weeks are mostly painless and minor vaginal bleeding, with some patients accompanied by mild abdominal pain, while others only show abdominal pain.
Scar pregnancy prevention
1. After cesarean section, special attention should be paid to safe contraception.
2. Avoid repeated uterine procedures such as abortion.
3. Women with uterine scars should pay attention to personal hygiene and sexual hygiene to avoid pelvic infections.
4. Women who have uterine scars and become pregnant again, regardless of whether they have scar pregnancies or not, should choose a tertiary hospital with a blood bank to terminate the pregnancy (give birth).
Diagnosis of Scar Pregnancy
Scar pregnancy is mainly manifested clinically as irregular vaginal bleeding after amenorrhea, sometimes accompanied by abdominal pain. Transvaginal ultrasound examination is the most important means of diagnosing scar pregnancy.
Ultrasound shows:
1. There is no pregnancy material in the uterine cavity and cervical canal, and it does not come into contact with the gestational sac;
2. The gestational sac is located on the anterior wall of the uterine isthmus, and the presence or absence of a embryo and fetal heartbeats depends on the size of the gestational week.
3. The uterine muscle layer tissue between the gestational sac and bladder is missing or absent, with a thickness of ≤ 5 FLLW. Combined with color Doppler flow imaging, it can display abundant blood flow inside and around the pregnancy, presenting a large number of venous blood flow spectra and arterial high-speed low impedance blood flow spectra.
Moreover, transvaginal three-dimensional ultrasound can more clearly display the thin uterine muscle tissue between the gestational sac and bladder wall, as well as the blood flow of the surrounding trophoblast layer. By observing the integrity of the gestational sac morphology and its position relationship with the cervical canal, it can distinguish it from cervical pregnancy caused by miscarriage and improve the accuracy of diagnosis.
The above introduces the symptoms of scar pregnancy, as well as the prevention and diagnosis of scar pregnancy, hoping to help everyone better understand scar pregnancy.
