Tubal intervention means that the doctor will take a tubal catheter and go deep into the fallopian tube through the vagina, then the doctor will take a coaxial catheter system through the TV screen to make a localized imaging of the fallopian tube and reopen the blocked part of the tube through the catheter wire. Tubal intervention is mainly suitable for tubal blockage and adhesion, which can serve both diagnostic and therapeutic purposes. However, after tubal intervention, a series of side effects may occur, such as pelvic infection, which can be prevented by taking antibiotics, and some girls may experience dizziness, headache, nausea, vaginal bleeding, lower abdominal pain, and most of the symptoms can be relieved by themselves. If the tubes are different again through diagnosis as well as treatment, they will need to be re-entered for tubal intervention, as well as tubal reconstruction surgery and IVF if necessary.
