Fallopian Angioplasty under Fiberscope (FT)

What is Fallopian Angioplasty under Fiberscope (FT)?

About 30% of infertility is caused by a tubal factor. Fallopian angioplasty under fiberscope (FT) is a treatment which is performed when obstructions, blockages or constriction of Fallopian tubes are found, by hysteron-salpingography (HSG). If there is a tubal obstruction the oocyte cannot meet sperm and cannot be fertilized.
There are two Fallopian tubes, and if one is obstructed it is a misconception to think that since the other is fine that there is no problem. It has been generally considered that ovulation occurs alternately between the 2 ovaries, but it has also been found that the right ovary may ovulate in succession, and so we can say that the same is true for the left ovary respectively. When ovulation occurs on the side where the Fallopian tubes are obstructed or closed, then it will not lead to a natural fertilization.
In addition, even if an oocyte makes it through one side, there are still some cases where the state of Fallopian tube is not good. The fallopian tubes have a series of small folds that will carry the oocyte by the movement of the folds. If the function is weakened, the oocyte will not be carried well, and fertilization will be more difficult.
The causes of obstruction can vary from endometriosis to chlamydia.
When you do Fallopian Angioplasty under Fiberscope (FT), together with the patency test, the fallopian tube can be restored, you can observe the state of the Fallopian tube directly with the Fiberscope. However, since the thickness of the Fallopian tube is 1mm or less, there are cases where the FT is done and the Fallopian tubes do not recover (about 5%) or FT is successful and obstructions yet again occur (about 10%).

Method of Fallopian Angioplasty under Fiberscope (FT)

A built-in balloon called an FT catheter about 1mm in size is used to do the treatment by using the fiberscope. The catheter is inserted into the uterus from the vagina, it extends the oviduct balloon incorporated in the catheter. At this time, it will restore the patency of the blockage or narrowing of the fallopian tube. In addition, the oviduct is observed directly with the fiberscope, so it is possible to know the state of the fallopian tube. Since it is also somewhat painful, intravenous anesthesia is used. The whole procedure takes about 20 minutes on one side, so about 30 to 40 minutes for both sides, and can be done as a simple day surgery.

(1)A thin tube called an FT catheter is inserted into the uterus through the vagina and using an endoscope the entrance to Fallopian tubes can be checked.


(2)Catheter balloons are continuously extended into the parts of the Fallopian tubes where there is a blockage or constricted areas and the balloon is used to expand them.


(3)The endoscope is located within the center of the balloon. After opening the site of obstruction, we will continue to observe the oviduct luminal surface while pulling the balloon back out.


Risks of Fallopian Angioplasty under Fiberscope (FT)

If there is a strong adhesion, there is a risk of perforation, if this happens we will stop the treatment and issue antibiotics and it should recover after rest. Normally, because there is no possibility to occur symptoms such as abdominal bleeding, and improve only with rest.

After surgery there may be abdominal pain or some bleeding or possible infection.
By the anesthesia, there may be other allergy and mood failure occurs. With anesthesia there may be an allergy or feel unwell.

Treatment and course after surgery

After FT, if pregnancy doesn’t occur after three attempts using the timing method or artificial insemination, it is considered that there is a fallopian tube problem, and IVF is recommended. (In addition, depending on the result of observation of the oviduct in the fallopian tube mirror, you may want to consider the step-up to early in vitro fertilization (IVF).)
