Description
Technical field
The present invention relates to the field of medical instrument technology, espespecially a kind of microtubular, Embolism for fallopian tube, is dredged, is made push component
Image device and application method.
Background technique
There is more patient to select vitro fertilization-embryo implanting (IVF-ET, also known as test-tube baby) for various reasons, takes
With relatively high, success rate is about 40-50%, is influenced in many reasons of IVF-ET success rate, hydrosalpinx be one very
Important reason.In recent years many studies have shown that, the presence of hydrosalpinx significantly reduces the Clinical Pregnancy Rate in of IVF-ET,
The even nearly half of rapid drawdown.
Fallopian tubal interventional embolization is to carry out mechanicalness embolism to therapy of oviduct using platinum microcoils, is passed through in art
Microcoils are sent to interstitial tubal and isthmus and complete embolism by microtubular, earliest mainly as a kind of sterilization or permanent contraception
Means.Platinum microsprings circle is made of platinum alloy, is clinically mainly used for the embolism of tiny blood vessels, has in microcoils
Fibre fluff can increase the compatibility with fallopian tubal inner wall, postoperative through aseptic can occur around microcoils after a period of time
Inflammation, to further strengthen the effect of embolism.
Fallopian tubal interventional embolization and currently used several hydrosalpinx treatment methods (such as salpingotomy, ligation,
Stoma with suction etc.) compare, its advantage is that not damaging the arch of aorta in mesosalpinx, do not influence blood supply and the function of ovary
Can, operation safety is high, noninvasive, is not required to anesthesia and completes to treat in outpatient service, can significantly improve hydrosalpinx patient test tube baby
The Clinical Pregnancy Rate in of youngster, while ectopic pregnancy risk is reduced, it is to go to test-tube baby but to have the Gospel of hydrosalpinx patient, more
It is a kind of up-and-coming interventional therapy new technology.
Hysterosalpingography is the method for most classic judgement uterine cavity and tubal patency situation, due to uterus and fallopian tube
The limitation of radiography (being the radiography of lipiodol or iodine water including contrast agent), that is, diagnostic result has false negative or false positive, especially
Be salpingemphraxis diagnosis there are clearly disadvantageous, the reason of cannot usually identifying salpingemphraxis.Such as fallopian tubal spasm or
Mechanical obstruction is film property adhesion, mucous plug obstruction or fibrous adherence obstruction etc., especially to interstitial portion salpingemphraxis
Diagnosis it is more inadequate, and selective salpingography then facilitates to identify Blocking Cause, and mucus embolus in this way, film property adhesion are then
It easily removes, separate, and make fallopian tube recanalization, the invasive surgeries such as unnecessary laparoscope, exploratory laparotomy can be removed from.
Hysterosalpingography (HSG) is to judge that fallopian tubal is logical according to how many contrast agent are remained in check plain film fallopian tubal
Smooth degree, commonly degree has to difference are as follows: it is unobstructed, logical and deficient it is smooth, logical and unsmooth, logical and extremely unsmooth, slightly lead to and substantially not
Logical pelvic cavity；HSG has certain limitation.And selective salpingography is that radiography is distinguished for left and right fallopian tubal, further according to
Pelvic cavity interimage agent smearing or disperse situation and fallopian tubal interimage agent residual is how many judges tubal patency degree, therefore to list
The diagnosis of adhesion situation is more accurate around the unobstructed degree of oviductus lateralis and fimbriated extremity of fallopian.
The therapeutic effect of selective salpingography is that (have anti-inflammatory and prevent adhesion by contrast agent and logical liquid drug solution
Effect) Fluid pressure generates the extruding of fallopian tubal, separation, so as to avoid caused by contrast agent (iodized oil and iodine aqueous solution)
Cornual sphincter spasm and uterine cavity dilatancy pain caused by salpingemphraxis illusion, to cannot be completely logical defeated again
The intervention of row seal wire is Salpingostomy to oviduct again, reaches the Precise Diagnosis in selective salpingography and certain therapeutic effect
On the basis of, therapeutic effect is further increased, the pregnancy rate of patient can be significantly improved, therefore on the basis of HSG, is into one
Step improves pregnancy probability, and reasonably selecting HSG is very important.
Efficacy of Fallopian Tube Dredging primary treatment because caused by fallopian tubal or pelvic peritoneum inflammation uterine tube stegnosis or blocking make
At female acyesis and aphoria.Clinically common Efficacy of Fallopian Tube Dredging has through uterine neck Efficacy of Fallopian Tube Dredging, palace laparoscope joint
Efficacy of Fallopian Tube Dredging.
