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.
