Fallopian tubes: improved technique for catheterization

Successful fallopian tube catheterization for diagnosis or treatment of infertility combines hysterosalpingographic and angiographic techniques. An improvement in the catheterization strategy was developed so that angled, tortuous, or more distally obstructed fallopian tubes could be catheterized. In 22 patients, 38 fallopian tubes were catheterized by using this strategy. In nine tubes (24%), forceful ostial injection alone of contrast material was able to open and/or depict the fallopian tube. In 13 tubes (34%), a discrete obstruction was recanalized by using the standard fallopian tube catheterization set. In 12 tubes (32%), successful recanalization required the use of a softer, tapered guide wire and catheter. In four tubes (10%), recanalization was unsuccessful.     

Selective osteal salpingography and transvaginal catheter dilatation in the diagnosis and treatment of fallopian tube obstruction

Selective salpingography and transvaginal catheter dilatation were performed in 157 women with infertility to diagnose, localize, and classify obstructive diseases of the fallopian tubes and to correct obstruction of the proximal (uterine-end) tube. In 61 (39%) of the patients, the selective salpingograms showed patent tubes despite the fact that two previous hysterosalpingograms showed obstruction of the proximal (uterine-end) tube. Transvaginal catheter dilatation successfully recanalized the proximal portion of the tubes in 79 (82%) of 96 patients with obstructed tubes. In 18 of 25 with successful transvaginal catheter dilatation and 6-month follow-up salpingography, the tubes remained patent. Coexisting disease of the distal (ovarian-end) tubes was diagnosed in 29 (18%) of the patients. Pregnancy was achieved in 11 of the 157 patients (six in whom obstructions were corrected by transvaginal catheter dilatation and five in whom selective salpingograms showed patent tubes). There were no complications due to the procedure. The excellent diagnostic and therapeutic yield, lack of complications, and low cost justify the use of these percutaneous techniques to investigate female infertility and to treat obstruction of the uterine end of the fallopian tube.     

Fallopian tube recanalization with a catheter system--experience in the use of a balloon catheter

Fallopian tube obstruction is one of the most difficult problems in the treatment of infertility. This report gives the results of a pilot study on the transcervical recanalization of the occlusive fallopian tube. Selective catheterization of the uterine cornu was applied through a balloon catheter, which was wedged at the internal uterine os. In 16 occlusive fallopian tubes of 11 cases, the catheterization procedure was attempted and accomplished with a 87.5% success rate. Recanalization was successful in 75.0% of the affected tubes. Subsequent pregnancy was confirmed in three cases. This convenient technique is safe and effective and it will be accepted as the first choice in the diagnosis and treatment of fallopian tube obstruction.

A review of selective salpingography and fallopian tube catheterization.

Use of selective salpingography and fallopian tube recanalization has revolutionized the diagnosis and treatment of infertility. Selective salpingography, a diagnostic procedure in which the fallopian tube is directly opacified through a catheter placed in the tubal ostium, has been used since the late 1980s to differentiate spasm from true obstruction and to clarify discrepant findings from other tests. In fallopian tube recanalization, a catheter and guide wire system is used to clear proximal tubal obstructions. The recanalization procedure is simple for interventional radiologists to perform and is successfully completed in most patients (71%-92%). Pregnancy rates after the procedure have been variable, with an average rate of 30%. The combination of selective salpingography with fallopian tube recanalization has improved the overall management of infertility caused by tubal obstruction. The same catheterization technique used in fallopian tube recanalization is currently being explored for use in tubal sterilization.     

Occlusion of the fallopian tube by selective transcatheter radiofrequency electrocoagulation: an experimental study in rabbits

PURPOSE: To test the feasibility of performing transcervical fallopian tube occlusion in a rabbit model with use of unipolar radiofrequency (RF) electrocoagulation. MATERIALS AND METHODS: Under fluoroscopic guidance, transvaginal catheterization of the right or left fallopian tube was first performed with use of a coaxial technique in 20 rabbits. With a metal guide wire protruding from the catheter serving as the active electrode, RF electrocoagulation was performed. The power output was set to 200 W and the current was applied for 20 seconds. The fallopian tube on the contralateral side and the uterus were used as controls. Rabbits were randomly designated to be killed either 2 days (group I, n = 10) or 30 days (group II, n = 10) after the procedure, and tubal patency and histologic changes were evaluated. RESULTS: In group I, significant necrosis of the endosalpinx caused by RF electrocoagulation was found in all 10 rabbits. In group II, the occluded fallopian tube showed fibrosis of the wall in all 10 rabbits, but there was no tissue damage to adjacent organs. Histologic findings in the contralateral fallopian tubes were normal in all 20 rabbits. CONCLUSION: Transcatheter RF electrocoagulation proved to be a safe nonsurgical alternative for occlusion of the fallopian tubes in rabbits.     

Transvaginal fallopian tube catheterization in an animal model

A rabbit model for testing the safety and effectiveness of diagnostic and interventional techniques of fallopian tube catheterization is presented. Hysterography with injection into the terminal portion of the uterine horn visualized the fallopian tube in only 6% of cases; however, this increased from 33% to 50% by pretreatment with progesterone, administration of glucagon or phentolamine, or increased pressure of injection with balloon obstruction of the uterine horn. Salpingography with a catheter introduced in the tubal ostium or directly inside the tube was most effective and resulted in a consistent (100%) visualization of the fallopian tube. The technique also allowed coaxial introduction of small diameter guidewires and catheters deep into the fallopian tube.     

99TcmO4-输卵管显像对不孕症患者腹腔镜手术的价值

目的应用99TcmO₄-输卵管显像研究不孕症患者X线子宫输卵管造影（HSG）显示机械性通畅输卵管的功能受损程度,进而研究99TcmO₄-输卵管显像对腹腔镜手术的价值。 方法对HSG显示至少一侧输卵管通畅或通而不畅的不孕症女性患者166例（通畅输卵管91条,通而不畅输卵管222条,单侧不通输卵管19条）行99TcmO₄-输卵管显像。并对HSG显示通畅的91条输卵管进行99TcmO₄-输卵管显像及腹腔镜对比分析。采用SPSS 17.0软件对HSG检查通畅输卵管99TcmO₄-显像的输卵管功能损伤程度与腹腔镜检查的输卵管通畅性进行比较并行χ2检验。 结果对HSG显示输卵管机械性通畅（包括通畅及通而不畅）的不孕症患者,99TcmO₄-输卵管显像结果显示输卵管功能受损的阳性率为78.3%。对不孕症患者HSG检查显示通畅的输卵管,行99TcmO₄-显像及腹腔镜结果比较,其差异有统计学意义（χ2=27.56,P < 0.05）。其中,若腹腔镜显示通畅,则放射性核素99TcmO₄-输卵管显像显示输卵管功能以正常及轻度受损为主;若腹腔镜显示通而不畅,则放射性核素99TcmO₄-输卵管显像显示输卵管功能以中、重度受损及无功能为主。 结论放射性核素99TcmO₄-输卵管显像对输卵管功能受损程度及通畅性的判断具有重要价值,对临床腹腔镜手术选择具有重要指导价值,尤其对HSG显示输卵管通畅的不孕症患者能否进行腹腔镜手术价值更大。     

Use of ethylene vinyl alcohol copolymer for tubal sterilization by selective catheterization in rabbits

PURPOSE: To assess the efficacy of ethylene vinyl alcohol copolymer (Uryx) in nonsurgically occluding the fallopian tube and achieving tubal sterilization in the rabbit model. MATERIALS AND METHODS: Ten mature virgin female New England rabbits underwent transvaginal selective bilateral fallopian tube cannulation with use of a coaxial catheter system under general anesthesia. Selective salpingography was performed bilaterally to assess patency of the fallopian tubes. Ethylene vinyl alcohol copolymer was injected unilaterally through a microcatheter to completely fill the middle portion of the tube. Three to seven days after injection, each animal was bred. Conception was determined by ultrasonography (US) 7-19 days after effective breeding. If pregnant, the rabbit was killed. Otherwise, it was permitted to rebreed until pregnancy was achieved. Histologic specimens of the fallopian tubes were prepared and analyzed. RESULTS: Patency of the fallopian tubes was demonstrated bilaterally in all animals by the free spillage of contrast material into the peritoneum. The delivery of ethylene vinyl alcohol copolymer into the fallopian tubes was successful in all animals but one, in which most of the plug almost immediately extruded into the uterus. Pregnancy was detected by US in the untreated fallopian tube in the nine rabbits that were receptive to breeding. No pregnancies were detected in the injected side. Histologic analysis demonstrated variable degrees of occlusion, fibrosis, and inflammation, with the majority of specimens demonstrating mild to moderate inflammation and moderate to marked fibrosis. CONCLUSION: Ethylene vinyl alcohol copolymer can reliably be placed nonsurgically via the transvaginal approach into the fallopian tubes with use of a coaxial catheter system. Ethylene vinyl alcohol copolymer appears to result in less fibrosis than previously investigated agents and demonstrates a 100% early sterilization rate in the rabbit model.

Selective fallopian tube catheterisation in female infertility: clinical results and absorbed radiation dose

Clinical results of fluoroscopic fallopian tube catheterisation and absorbed radiation doses during the procedure were evaluated in 30 infertility patients with unilateral or bilateral tubal obstruction documented on hysterosalpingography. The staged technique consisted of contrast injection through an intraurine catheter with a vacuum cup device, ostial salpingography with the wedged catheter, and selective salpingography with a coaxial microcatheter. Of 45 fallopian tubes examined, 35 (78%) were demonstrated by the procedure, and at least one tube was newly demonstrated in 26 patients (87%). Six of these patients conceived spontaneously in the follow-up perod of 1–11 months. Four pregnancies were intraurine and 2 were ectopic. This technique provided accurate and detailed information in the diagnosis and treatment of tubal obstruction in infertility patients. The absorbed radiation dose to the ovary in the average standardised procedure was estimated to be 0.9 cGy. Further improvement in the X-ray equipment and technique is required to reduce the radiation dose. Correspondence to: T. Ishigaki

Tubal obstruction after ligation reversal surgery: results of catheter recanalization

PURPOSE: To evaluate the role of transcervical fallopian tube catheterization in restoring tubal patency after ligation reversal surgery. MATERIALS AND METHODS: Twenty-four women with tubal obstruction after ligation reversal surgery underwent selective salpingography and tubal recanalization. RESULTS: Patency was established in 26 (68%) of 38 anastomotic tubes without complication. In the 13 patients who were followed up and who could conceive only via a recanalized anastomotic tube, there were six (46%) pregnancies: two (15%) successful uterine pregnancies, two (15%) early spontaneous abortions, and two (15%) tubal pregnancies. The mean time from procedure to conception was 2 months. CONCLUSION: Patency of fallopian tubes not visualized at hysterosalpingography after ligation reversal surgery can be established 68% of the time with selective salpingography. In some patients, selective salpingography can be therapeutic. If subsequent conception occurs in these patients, it occurs shortly after the catheterization procedure.
