Description
Technical field
The present invention relates to a kind of hydrosalpinx treatment auxiliary equipment, in particular a kind of fallopian tube embolus and matching used
Pusher.
Background technology
Hydrosalpinx is the complication that chronic salpingitis is common, and Chang Yinwei acute inflammation, without healing, is lost after having in fallopian tube
Inflammation cause fallopian tube adhesion and locking, after tube chamber transudate or pyosalpinx absorb, remaining liq forms hydrosalpinx,
It is the common factors causing infertility, there is no satisfied Therapeutic Method at present.Containing microorganism, lymph in hydrosalpinx
Cell and some noxious substances, hydrops backflows into uterine cavity, not only effect toxic to embryo, it is also possible to washing away embryo affects it and
Bed, endometrium receptivity reduces, and Embryo Implantation Rate in and the Clinical Pregnancy Rate in of test-tube baby (IVF-ET) are all restricted, and closes
And the clinical pregnancy success rate of hydrosalpinx only has 10-20%, and rate of spontaneous abortion relatively significantly raises without hydrops person, therefore,
Before carrying out test-tube baby, various prevention hydrops is used to flow into the method for uterine cavity to improve the effect of test-tube baby.The most defeated
The main pretreatment mode of oviduct hydrops divides 4 kinds, salpingectomy, salpingostomy, therapy of oviduct ligation and B ultrasonic
Hydrosalpinx is aspirated under supervision.Former three is both needed under peritoneoscope or trans-abdominal performs the operation, and operation process may damage ovary
The vessel branch in palace, causes ipsilateral ovarian blood supply to reduce, has a certain impact ovarian function, although and aspirating hydrosalpinx
Do not interfere with ovary blood supply, but have the possibility that tubal pregnancy and hydrops again occur.Embolism for fallopian tube art is in early days for defeated ovum
Pipe Cost Saving, development in recent years is at IVF-ET pre-treatment hydrosalpinx, and this new Therapeutic Method both will not damage ovary week
Enclose blood supply, tubal pregnancy and hydrops recurrence can be avoided again, compensate for the deficiency of above 4 kinds of methods, make patient avoid hands
The hardship of art.
Being the microcoils of a platinum material the most clinically for the material that hydrosalpinx bolt is stifled, original purposes is that bolt blocks up blood
Pipe, sends microcoils into interstitial tubal by microtubular under x-ray monitors, the advantage of microcoils is not damage defeated ovum
Piping film and the blood supply of ovarian artery, simplicity, safety, without complication, shortcoming is material expensive, and roentgen radiation x is the most unfavorable
In women 's fertility.Place the patient's radiography again after embolus, find to reach the complete bolt of fallopian tube block up effect close to 100%, clinical
After Research Review analysis Embolism for fallopian tube, patient carries out the clinical effectiveness of IVF-ET, finds that pregnancy rate is cut with fallopian tube under peritoneoscope
Except art is similar with the treatment effect of neostomy, but which reduce operation risk, do not affect the blood supply of ovarian artery, to ovary
The impact of function is little, is conducive to improving the success rate of IVF-ET.
The treatment of Embolism for fallopian tube is innovation, an effective method, compared with at present conventional method, without operation and
Complication of anesthesia, easy, safety, economical, on ovarian function without impact, improve the clinical effectiveness of test-tube baby, have very well
Potential applicability in clinical practice.
Although at home and abroad can see product or the design of fallopian tube embolus, but these emboluses are all by what sterillization used, its
The bolt resistance treatment of the hydrosalpinx of supplementary reproduction also it is unfavorable in design.Such as, these emboluses are all fixed on uterine tube stegnosis
Portion, and reserve a segment trailer in uterine cavity, it is beneficial to cause the inflammatory reaction having sterilization effect, and is also beneficial to take out in the future
Embolus.But this pattern creates sterilization effect while bolt hinders, be not suitable for the supplementary reproduction purpose of hydrosalpinx treatment.
Hydrosalpinx bolt currently without supplementary reproduction hinders special embolus, and the fallopian tube embolus of sterillization is not suitable for helping reproduction
Hydrosalpinx bolt resistance, and use at present bolt block up blood vessel platinum material microcoils as hydrosalpinx bolt hinder,
Its not only material expensive, and need under roentgen radiation x, carry out bolt resistance operation and be also unfavorable for women 's fertility, the most also block up blood vessel because of bolt
Design the most entirely appropriate fallopian tube structure and time have the bolt resistance situation such as come off to occur.
