Wire Guide Canalization

When selective salpingography to remove a tubal obstruction does not work, wire guide canalization may be performed to make the fallopian tube patent. In this procedure, a 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 fallopian 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.

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.
