Ectopic pregnancy occurs in how many days of pregnancy is closely related to the site of ectopic pregnancy. Ectopic pregnancy occurs mainly in the isthmus of the fallopian tube, the jugular or umbilical end of the fallopian tube, and the interstitial part of the fallopian tube.
1. Tubal isthmus: mostly occurs around 6 weeks of pregnancy. The isthmus of the fallopian tube is too thin because of the muscle layer, blood transport is not good, the development of the fertilized egg in this area is limited, so that about 6 weeks of pregnancy can occur in the fallopian tube pregnancy miscarriage or rupture. Once rupture occurs, it is a gynecological emergency abdomen, requiring immediate surgery.
2. Pelvic or umbilical segment of fallopian tube: these two parts are slightly more spacious than the isthmus of fallopian tube, so the fertilized egg can survive for a longer period of time here, about 8-12 weeks or so, but the final outcome is also miscarriage or rupture. Similarly, once ruptured, it is also a gynecological emergency and requires immediate surgery.
3. Interstitial part of fallopian tube: pregnancy in this part is often confused with uterine horn pregnancy in clinic. The muscle layer in this part is thicker and blood flow is richer, so the fertilized egg can survive for a longer period of time in this part, about 12-16 weeks, but once rupture occurs, this symptom is extremely serious and the prognosis is not good.
If a woman is diagnosed with ectopic pregnancy after relevant examinations, she should be actively hospitalized. Because the end of ectopic pregnancy is not only miscarriage is rupture, once the rupture occurs is a gynecological emergency abdomen, need to be operated immediately, otherwise it will endanger the life of the pregnant woman.
