The fallopian tubes are tubular structures that are attached to the right and left sides of the uterus. Each tube is about the size of a pencil and consists of a lumen surrounded by smooth muscle. The lumen is trumpet shaped, the end attached to the uterus is narrow and the end adjacent to the ovaries is wide.
The fallopian tubes have three important functions:
- picking up the eggs (oocytes) from the ovary
- fertilizing the oocytes
- transporting the fertilized ovum into the uterus
3D Sonohysterography is a diagnostic test involving the use of saline as a contrast agent inside the uterine cavity. Injecting saline into the uterine cavity increases the ability to see problems in the cavity and in the wall (myometrium) of the uterus.
What to expect
A hysterosalpingogram (HSG) is done by placing a speculum into the vagina, cleaning off the cervix with a mild soap solution and then passing a thin catheter through the cervix into uterine cavity. Contrast or “dye” is then slowly injected into the uterine cavity. As the contrast passes through the fallopian tubes, X-ray images are taken. The catheter is then removed and images of any uterine or tubal abnormality can be studied and reviewed with the patient.
Interpreting the results of an HSG
If an abnormality is found following the HSG, this usually requires further evaluation and treatment. In some cases, further intervention is may not be required to correct the abnormality, and your provider will prevent specific treatment options to you.
