Patient's question:
The YJ who arrived on the 16th has been here for 42 days now. The urine test is positive, and there is a liquid dark area in the uterus, measuring 0.5cm x 0.5cm. No embryonic tooth tissue is visible. No obvious masses are detected in both adnexa. What are the causes of ectopic pregnancy?Doctor's answer:
1. Tubal inflammation is the main cause of ectopic pregnancy, which can be divided into tubal mucosal inflammation and peri-tubal inflammation.2. History of ectopic pregnancy or surgery: A history of ectopic pregnancy, whether naturally resolved after conservative treatment or undergoing conservative tubal surgery, increases the risk of recurrence by 10%.
3. Tubal developmental abnormalities or functional disorders, such as excessively long tubes, poor muscle layer development, lack of cilia in the mucosa, double tubes, tubal diverticula, or accessory fimbriae, can all lead to ectopic pregnancy.
4. Assisted reproductive technologies.
5. Failure of contraception.
6. Other factors, such as uterine fibroids or ovarian tumors compressing the fallopian tubes, can obstruct tubal lumen patency, hindering the movement of the fertilized egg.
