Hysteroscopic Tubal Cannulation

The doctor inserts a tube guided over a wire to the affected area under hysteroscopy guidance. After that, the blocked area in the fallopian tube is opened using a balloon on the catheter. Tubal cannulation is performed. During this procedure, the dye is flushed through the catheter to confirm patency of tubes. A sedative may or may not be used during this procedure.

The patient is recommended to follow the doctor’s instructions after the procedure to maintain the best results. In some selected cases, tubal cannulation has found to have good success rates similar to IVF. However, it also avoids the risk of ovarian hyperstimulation and multiple pregnancies. It is also possible that the woman will have subsequent spontaneous pregnancies following the procedure. Pregnancy rates depend on the:

Location of the blockage.
Specific procedure performed.
Cause of the blockage.

Persisting infertility
Perforation in the wall of the Fallopian tube
Inflammation of the abdominal cavity called peritonitis
Haemorrhage (bleeding into the abdominal cavity)

In rare cases, some patients have faced the following:

Blockage in the Fallopian tube is normally found in the distal part (closest to the ovary) or in the isthmus (the narrowest part)
Heavy scarring of the fallopian tubes
Fallopian tubes active inflammation
Tubal tuberculosis
