Conception rates after fluoroscopy-guided fallopian tubal cannulation: an alternative to

Previous studies show good technical success rates for fallopian tube recanalization. Scarce literature exists regarding advance techniques currently used by interventional radiologists during fallopian tube recanalization procedures. This study investigates the level of intervention and tubal patency and its association with technical success and associated pregnancy outcomes. We retrospectively evaluated fallopian tube recanalization procedures performed at a single center in a 24-year period. A total of 160 couples undergoing a basic infertility evaluation were included. Hysterosalpingography with high pressure contrast injection followed by selective contrast, guidewire catheterization at the tubal ostium, and/or microcatheter/microwire recanalization were performed. Comparisons of the tubal fertilization rate by relevant characteristics were tested for statistical significance with Technical success rate was 94% (319 of 341 tubes). High pressure contrast injection alone (184 of 341, 54%), selective catheterization (40%), and microcatheter/microwire (6%) interventions yielded technical success rates of 98%, 90%, and 73%, respectively. The overall rate of conception was 35% (17 of 48). Current techniques of fallopian tube recanalization offer a desirable and safe option with high technical success for patients seeking treatment for infertility due to proximal fallopian tube obstruction.
