What causes ectopic pregnancy?

Ectopic pregnancy is an abnormal pregnancy process in which the fertilized egg implants and develops outside the uterine cavity. The causes of this disease are complex and varied, including fallopian tube problems, intrauterine contraceptive devices, wandering fertilized eggs, disease factors, multiple abortions, etc.

1. Fallopian tube problems: Fallopian tube inflammation, including fallopian tube mucositis and perisalpingitis, can lead to narrowing of the lumen and weakened peristalsis of the smooth muscle of the tube wall, which is not conducive to the movement of the fertilized egg. Hypoplastic or dysfunctional fallopian tubes, such as excessively long fallopian tubes, poorly developed muscular layer, and lack of mucosal cilia, can also increase the risk of ectopic pregnancy. For fallopian tube inflammation, anti-infection treatment is required first, and then surgical treatment or assisted reproductive technology is considered. If there is a desire to have children, fallopian tube plasty or assisted reproductive technology can be considered.

2. Intrauterine contraceptive device: If the intrauterine contraceptive device fails to prevent pregnancy and pregnancy occurs, the risk of ectopic pregnancy increases. If ectopic pregnancy occurs, surgical treatment or drug treatment should be selected according to the specific situation.

3. Migrant fertilized egg: The fertilized egg migrates in the fallopian tube and the migration time is too long, resulting in implantation in the fallopian tube. Surgical treatment is the main method, such as salpingectomy, laparoscopic surgery, etc.

4. Disease factors: Tumors around the fallopian tubes, such as uterine fibroids and ovarian tumors, affect the patency of the fallopian tube lumen. Endometriosis increases the possibility of fertilized eggs implanting in the fallopian tubes. Surgery to treat tumors or endometriosis and ectopic pregnancy at the same time. Choose the appropriate surgical method according to the patient's condition, such as laparoscopic surgery.

5. Multiple artificial abortions: Repeated and frequent artificial abortions lead to endometrial trauma, making it difficult for the embryo to implant in the uterine cavity. Drug treatment is suitable for early ectopic pregnancy, but the risk of fallopian tube obstruction should be noted. Surgical treatment, such as laparoscopic surgery, can preserve the function of the fallopian tube and is suitable for patients who want to have children.

Patients with ectopic pregnancy should seek medical attention in a timely manner and choose appropriate treatment methods according to the doctor's advice to reduce harm to the body.
