Approach to tubal obstructive infertility

  Tubal infertility is a common disease of the reproductive system and there are many factors leading to female infertility: tubal obstruction is the most common cause, accounting for 30% to 40% of the cases, and the fallopian tubes are usually divided into four parts: the interstitial part, the narrow part, the abdomen and the umbrella part. The treatment effect is determined by different obstruction sites. Usually, the treatment of interstitial and narrow obstruction is relatively easy and the conception rate is higher, while the obstruction in the abdomen and umbrella of the fallopian tube is usually accompanied by hydrosalpinx, which is relatively complicated and the conception rate is relatively low. Interventional minimally invasive recanalization with little damage is completely available for narrow and interstitial tubal obstruction. It has been carried out for more than 10 years in the treatment field. Its treatment method is to perform micro-catheterization after tubal imaging under the monitoring of digital DSA machine with the patient fully awake; it is relatively easy to operate and is the best indication for proximal tubal obstruction infertility. According to statistics, the success rate of recanalization can reach 95-98% and the pregnancy rate is over 50%.  The advantages of minimally invasive tubal intervention under DSA: 1. More precise: the soft wire is precisely delivered to the obstruction site under digital DSA to directly unblock the fallopian tubes. 3. Safer: the micro-guide wire enters the uterine cavity, causing no harm to the uterus and no damage to the human body.  2, more efficient: the unblocking and treatment are completed simultaneously through the micro-guide wire, and anti-adhesion drugs are injected at the same time of unblocking to avoid the problems of traditional ventilation, water and repeated adhesions. The whole treatment process of silk technology is guided by light source technology and operated under visualization to ensure smooth operation.  4.More relaxed: no incision, no pain, fast recovery, shorter treatment time, the whole unblocking process only takes 3~5 minutes, compared with the hard guidewire treatment process shortened by 6 times.  5, speed up the time of pregnancy: under the digital DSA, the display clarity is good and the patient can try to conceive as soon as the next month with little damage.
