Mid-Segment Tubal Blockage

Definition - What does Mid-Segment Tubal Blockage mean?

Mid-segment tubal blockage is the blockage at the mid portion of the fallopian tube. While the condition is not as common as distal tubal blockage, it can still drastically weaken a woman’s ability to get pregnant.

FertilitySmarts explains Mid-Segment Tubal Blockage

Mid-segment tubal blockage occurs due to damage or scarring of the midsection of the tube, most often as a result of tubal ligation (a birth control procedure).

The midsegment is close to the ampullary area of the fallopian tube where fertilization takes place. Blockage of this segment can keep the sperm from fertilizing the egg, leading to infertility.

The condition can be diagnosed with an X-ray procedure called hysterosalpingography. A failure of the dye to flow out of the mid-segment indicates a mid-segmental tubal blockage.

A well-executed microsurgical rejoining of the fallopian tube segments, a procedure called tubal reanastomosis can yield the same pregnancy rate as that of three IVF attempts.

Alternatively, the doctor may surgically rejoin the tube using a robotic-assisted laparoscopic surgery, which is minimally invasive as well as enables a more magnified view of the interior. Its surgical results are expected to be on par or even outdo those of the microsurgical technique because of the reduced chances of scarring. In women younger than 35 years, robotic-assisted laparoscopic tubal reanastomosis is the recommended, less expensive alternative to IVF.

The surgical repair of the fallopian tubes is all but obsolete and is now replaced with assisted-reproduction. Delaying IVF because of surgery further curtails the chances of conception, particularly after the age of 35 years.
