Hysterosonograms (HSN)

Hysterosonogram (HSN) is sort of a combination of a HSG and ultrasound. However, instead of using radio-opaque dye and x-rays to "see" the uterus, we use saline (salt water) and high-resolution ultrasound.

The result is a very sensitive method for visualizing abnormalities inside the uterus. Hysterosonograms are more "comfortable" than HSG, which sometimes causes cramping. Hysterosonograms, however, cannot replace hysterosalpingograms when it comes to evaluations of fallopian tubes.

This patient came to us having failed five IVF cycles at another program. The hysterosonogram revealed scar tissue (adhesions) inside the uterine cavity. Interestingly, an HSG performed previously did not demonstrate any adhesions.

Fluid which passed through the fallopian tubes allowed this view of pelvic adhesions from the fallopian tube to the uterus.

This infertility patient conceived with the use of gonadotropins (injectable fertility medications). The amnion (thin membrane surrounding the embryo during pregnancy) is clearly seen.

Using color flow doppler, blood flow is seen in the early embryo.
