Fallopian tube recanalization (FTR) is a specialized, non-surgical procedure used to clear blockages in the fallopian tubes. The fallopian tubes carry eggs from the ovaries to the womb. If these tubes are blocked (often by mucus or minor scarring, known as proximal tubal occlusion), the egg and sperm cannot meet, which is a common cause of female infertility.
Rather than performing major surgery, an interventional radiologist uses live X-ray guidance (fluoroscopy) to pass a tiny catheter through the vagina and cervix directly into the blocked tube to clear it.
Common Indications for Fallopian Tube Recanalization (FTR)
- Treating female infertility caused by proximal fallopian tube blockage (blockage near the womb).
- Following up on an abnormal hysterosalpingogram (HSG) that showed blocked tubes.
- Restoring tubal patency before attempting intrauterine insemination (IUI) or other fertility treatments.
What exactly does Fallopian Tube Recanalization (FTR) show?
Under live X-ray guidance, contrast dye is injected to show the exact shape and path of the fallopian tubes. It visualizes the blockage clearing in real-time as the catheter passes through, showing the dye spilling freely into the pelvis, which confirms the tubes are open.
How should I prepare for Fallopian Tube Recanalization (FTR)?
The procedure is usually scheduled in the first half of your menstrual cycle (days 5 to 12, after your period has ended) to ensure you are not pregnant. No fasting is required, but you may be asked to take a mild sedative or pain reliever (like ibuprofen) one hour before the appointment to minimize cramping.
Do I need to stop taking medication?
No. Continue taking your routine medications. Let the doctor know if you have any allergies to contrast dye or iodine.
What happens when I arrive for my scan?
You will change into a hospital gown. You will lie on the X-ray table with your feet in stirrups, just like a standard pelvic exam. The doctor will insert a speculum into your vagina to view the cervix and clean the area with an antiseptic solution.
How is the procedure performed?
The doctor will guide a small catheter through the cervix into the womb. They will inject contrast dye (making you feel a mild cramping sensation) to locate the openings of the fallopian tubes. Under live X-ray guidance, they will insert an extremely thin wire and microcatheter into the blocked tube, gently pushing through the mucus plug or blockage. Once cleared, more dye is injected to confirm that the tube is completely open.
How long does Fallopian Tube Recanalization (FTR) take?
The entire procedure takes about 20 to 30 minutes.
Is there any discomfort?
Yes. You will feel menstrual-like cramping when the speculum is placed and when the contrast dye is injected to fill the womb. The cramping can feel intense for a few minutes but quickly resolves once the dye is drained. The team will work gently to minimize discomfort.
Are there risks?
Yes, but they are very small. There is a minor risk of pelvic infection or a very small risk of making a hole in the fallopian tube (perforation), which usually heals on its own. The procedure uses a low dose of radiation, similar to a standard pelvic X-ray.
Can children have this scan?
This procedure is performed on adult women undergoing fertility evaluations.
Can I have this scan if I am pregnant?
Pregnancy Precaution
This procedure is never performed during pregnancy. It is carefully scheduled in the early phase of your menstrual cycle specifically to avoid any radiation exposure to a developing embryo.
When will I get my results?
The doctor will watch the tubes open in real-time. They will discuss the results with you immediately after the procedure and send a formal report to your gynecologist or referring doctor within 24 hours.
What if the scan finds something?
If the tubes are successfully cleared, your referring doctor will discuss timing for conceiving naturally or starting fertility treatments. If the tubes cannot be cleared due to severe scarring, they will discuss alternative options, such as IVF.
Conclusion
Fallopian tube recanalization is a safe, outpatient procedure that successfully clears blocked tubes in up to 90% of cases. To ensure a comfortable recovery, rest for the remainder of the day, and drink plenty of fluids.
