What is ectopic pregnancy?

For women of childbearing age, it is important to understand what ectopic pregnancy is and how to effectively prevent it, because the harm caused by ectopic pregnancy is very serious. For example, chronic fallopian tube inflammation and pelvic tumors may induce ectopic pregnancy.

1. Chronic salpingitis

(Chronic salpingitis can cause adhesion of the fallopian tube mucosal folds, leading to stenosis of the lumen, mucosal destruction, loss of epithelial cilia, adhesion around the fallopian tube, and distortion of the tube. The above conditions affect the normal operation and passage of the fertilized egg in the fallopian tube and are the main cause of tubal pregnancy.

2. Fertilized eggs travel abroad

After the fertilized egg is fertilized in one fallopian tube, it can swim along the umbrella end to the opposite fallopian tube. Due to the extension of time, it has the ability to implant before it reaches the uterine cavity, thus forming an ectopic pregnancy.

3. Pelvic tumors

Pelvic tumors compress or pull on the fallopian tubes, causing them to shift or deform, blocking the passage of the fertilized egg. This is also the cause of ectopic pregnancy and the cause of the symptoms of ectopic pregnancy.

4. Hypoplasia of the fallopian tube

Abnormal fallopian tube development or function Abnormal fallopian tube development such as excessively long fallopian tubes, hypoplastic myometrium, absence of mucociliary tissue, double fallopian tubes, and extra fimbria can all be the cause of tubal pregnancy. The physiological functions of the fallopian tube are complex. The peristalsis of the fallopian tube wall, ciliary activity and secretion of epithelial cells are all regulated by estrogen and progesterone. If the balance between the two hormones is disturbed, it will affect the transportation of the fertilized egg and cause fallopian tube pregnancy.

Regardless of whether tubal sterilization is performed by ligation, electrocoagulation or cuffing, if a fallopian tube fistula is formed or recanalization occurs, it may lead to tubal pregnancy. Recanalization or tuboplasty after tubal sterilization may also cause scarring that narrows the lumen and results in poor patency, leading to disease.
