Wire Guide Canalization

When selective salpingography is to remove a tubal obstruction does not work, wire guide canalization may be performed to make the fallopian tube patent. In this procedure, thin, flexible wire is carefully threaded through a selective salpingography catheter, and passed directly inside a fallopian tube. This technique, which is analogous to using a plumber's "snake" to open a blocked drain, is another technique CHR physicians developed to open a blocked tube.

"Wire-guide canalization originated at CHR, where it was developed by Dr. Norbert Gleicher."

CHR's Medical Director, Dr. Gleicher, invented the concept of recanalizing obstructed fallopian tubes with catheters under x-ray guidance. Today this is a technique widely practiced by radiologists. However, to the best of our knowledge, CHR is the only fertility center with physicians who perform this treatment.

Another use for this technique is to lower the tubal perfusion pressure (TPP) measurements in women with high levels. However, there is no convincing data that reducing TPP in this way allows these women to achieve a pregnancy rate similar to those who have a low TPP.

Trained and experienced physicians perform all of these procedures at CHR. They take little additional time compared to a basic HSG, and provide considerable additional, clinically useful information as well as treatment options.
