Selective transcervical fallopian tube catheterization: technique update

A technique of transcervical fallopian tube catheterization involving use of a new vacuum hysterograph and coaxial catheter set is described. In 25 women, selective catheterization of the uterine cornua was accomplished with a 94% success rate. Ostial salpingography permitted visualization of 26% of the 46 tubes found to be obstructed or poorly visualized with conventional hysterosalpingography. Recanalization was successful in 96% of 28 proximal tubal obstructions and in 33% of six midisthmic obstructions unrelated to surgery. Recanalization attempts resulted in tubal perforations without apparent clinical effects in four tubes, one with proximal and three with midisthmic postsurgical obstructions. The new hysterograph with coaxial catheter set is more suitable for recanalization of the obstructed fallopian tubes than is the previously used balloon catheter set.
