What reason is pregnancy after ligation?

summary

Tubal ligation is to cut off, ligate, electrocoagulation, clamp, loop the fallopian tube, or use drugs to block or plug the fallopian tube cavity, so that sperm and eggs can not meet to achieve the purpose of sterilization. It is a relatively safe and permanent contraceptive method. The operation can be performed through abdominal wall or vaginal fornix, or directly through uterine cavity. What reason is pregnancy after ligation? Let's talk about it.

What reason is pregnancy after ligation?

1. This is caused by the recanalization of the amputated or blocked fallopian tube. Practice has proved that the success rate of female tubal ligation is generally very high, which can make the vast majority of women infertile for life, but there is also a certain failure rate. Individuals will still be pregnant when they have the following situations.

2. It is related to the method of ligation. Simple ligation may cause the ligation line to slip and recanalize, and the time of tubal ligation and sterilization is usually after postpartum or induced abortion. At this time, the tubal is congested, edematous, and the tissue is fragile. For example, when ligating with silk thread, the tubal becomes thinner with the involution of postpartum uterus, but the tightness of ligation silk thread remains unchanged, Therefore, the ligation site may be naturally loose and the lumen may be recanalized. If the ligation is too tight, the silk thread can cut off the fallopian tube and form the fallopian tube abdominal cavity leak. If the leak is the fallopian tube near the uterine segment, the egg can enter the fallopian tube cavity from the leak, so with the chance of sperm and egg meeting, you can get pregnant. It is related to the method of ligation. At present, embedding ligation is more often used, and recanalization is less likely.

3. It is related to the position of tubal ligation. If the ligation site is in the isthmus of the fallopian tube, and the local tissue contusion is too much, sometimes it may be necrotic and fall off, and then the two stumps of the fallopian tube can be connected and recanalized by themselves.

matters needing attention

As a matter of fact, there is no contraceptive method that can achieve 100% contraceptive effect at present. Even the internationally recommended contraceptive tools and short acting contraceptives can achieve 99% success rate, but they can not avoid that 1%. However, the phenomenon of re pregnancy after tubal ligation is rare, and women friends need not worry too much, but if there is menstrual disorder or amenorrhea after tubal ligation, they still need to see a doctor as soon as possible to eliminate the possibility of pregnancy.
