Early symptoms of scar pregnancy, be more alert!

The incidence of scar pregnancy is increasing. Many pregnant women generally do not have obvious discomfort symptoms in the very early stages of pregnancy. The clinical manifestations from 5 to 16 weeks are mostly painless, small amounts of vaginal bleeding. Some patients have mild abdominal pain, while some patients only show abdominal pain.

1. Causes of scar pregnancy

The pathogenesis of scar pregnancy is still unclear, but it is generally believed that the fertilized egg may be implanted in the scar tissue through the tiny cavity between the endometrium and the cesarean section scar. The gestational sac is then surrounded by the muscle layer and fibrous tissue of the scar tissue and is completely isolated from the uterine cavity. It is currently believed that in addition to cesarean section, other uterine surgeries can also form tiny cavities between the endometrium and surgical scars, such as curettage and hysteroscopy.

The destruction of the endometrium and myometrium and poor scar healing after cesarean section are the predisposing factors for cesarean scar pregnancy. The increased number of cesarean sections, breech presentation cesarean sections, and suture hormones are all related to the occurrence of scar pregnancy.

In addition to cesarean section, repeated abortions, uterine operations such as hysteroscopy, myomectomy, in vitro fertilization and other assisted reproductive technologies may cause varying degrees of injury to the uterus, which will also form scars in the uterus.

2. Symptoms of scar pregnancy

Pregnant women who experience scar pregnancy generally do not have obvious discomfort symptoms in the very early stages of pregnancy. The clinical manifestations of 5 to 16 weeks are mostly painless, small amounts of vaginal bleeding, some patients have mild abdominal pain; some patients only experience abdominal pain.

Because there is no obvious discomfort, if the patient seeks medical treatment, the gynecologist cannot make a diagnosis during clinical examination because the size of the uterus is not significantly different from that of a normal pregnancy and the cervical examination is often normal. This brings trouble to the patient's early detection and early treatment.
