What are the symptoms of horn pregnancy?

Many female friends will encounter some special situations during pregnancy due to many factors. Cornual pregnancy is a common situation. Cornual pregnancy is what people often call ectopic pregnancy in life. When female friends have this situation, if the situation is serious or even life-threatening, some female friends do not know what the symptoms of cornual pregnancy are. So, what are the symptoms of cornual pregnancy?

First, what are the symptoms of horn pregnancy? There are no symptoms in the early stages and it is not easy to be detected. As the embryo develops and grows, the space in the uterine horns becomes limited, the uterine wall becomes thinner, and the tension increases, and abdominal pain symptoms may occur. The narrow placental attachment site may cause partial fetal detachment, resulting in vaginal bleeding or even miscarriage. When the embryo develops to 8-12 weeks, the tension on the uterine horns is greater and the uterine walls are thinner, which may lead to rupture of the uterine horns and heavy bleeding. Because the uterine artery and the ovarian fallopian tube arteries cross and anastomose with each other in the uterine cornu, they are richly supplied with blood. Once ruptured and bleeding occurs violently, the patient may quickly go into hemorrhagic shock. If not treated in time, it may lead to the patient's death. A small number of patients can develop to full-term pregnancy and delivery, but it is often prone to retained placenta.

Second, asymptomatic patients can receive expectant treatment, be closely observed, and expect the embryo to grow into the uterine cavity, leading to normal delivery. During this period, you should avoid strenuous activities and undergo regular ultrasound monitoring under the guidance of a doctor. Aspiration uterus was performed under B-ultrasound monitoring. If the embryo is large and the uterus is thin, laparoscopic aspiration or incision can be performed to extract the embryo. In case of rupture and severe bleeding, laparoscopic hemostasis repair or uterine angle resection can be performed immediately. If conditions are unavailable, emergency laparotomy should be performed. Cornual pregnancy is a pregnancy in which the embryo is implanted in the uterine cavity at the cornu near the junction of the uterus and the opening of the fallopian tube. It is not an ectopic pregnancy by strict definition. As the pregnancy progresses, there are three possible outcomes: the gestational sac stops developing, leading to miscarriage; the gestational sac expands outward at the uterine cornu, causing the uterine cornu to swell and protrude outward, eventually leading to uterine cornu rupture; or the gestational sac expands into the uterine cavity, and the pregnancy can be delayed to the late stage and result in natural delivery. Because the uterine cornu has thin muscle tissue and is the anastomosis site between the uterine blood vessels, ovarian arteries and veins, and fallopian tube blood vessels, it has rich blood supply. If the gestational sac is implanted here, the muscle layer may rupture as the pregnancy progresses, causing heavy bleeding. If the diagnosis is delayed, it may be life-threatening.

What are the symptoms of horn pregnancy? It manifests as asymmetrical enlargement of the uterus. Due to the thick local muscle layer, there may be no symptoms before rupture. In some cases, miscarriage is the pregnancy outcome. The pregnancy lasts longer, and it is often delayed until 8 to 12 weeks of pregnancy before the patient comes to the hospital for treatment. When visiting the doctor, the patient often complains of severe abdominal pain, which may or may not be accompanied by vaginal bleeding. Moreover, once the uterine cornua ruptures, the exhalation will be violent and the patient may experience severe abdominal pain and rapid shock symptoms. Most patients with cornual pregnancy can continue their pregnancy, but they may experience persistent pelvic pain and recurrent vaginal bleeding during pregnancy, uterine rupture during pregnancy and/or delivery, and retained placenta in the third stage of labor.
