Sonohysterosalpingogram with FemVue is a simple, well-tolerated ultrasound procedure used to evaluate the patency of the fallopian tubes and to detect abnormalities of the uterus. The procedure usually takes between 10 and 30 minutes to complete, and the results are available immediately. Because FemVue only uses saline, air, and ultrasound to during the procedure, it is a safe and reliable alternative to the conventional hysterosalpingogram which uses x-rays and x-ray contrast dye.

The best time to have this procedure done is between Day 5 and Day 10 of your menstrual cycle (which Day 1 being the first day of bleeding during your period).

What to Expect During the Procedure

A sonohysterosalpingogram with FemVue begins like the first part of a pap smear, with a vaginal speculum gently inserted into the vagina to visualize the cervix. The cervix is then cleansed with antiseptic solution to decrease the risk of infection. A thin flexible balloon catheter is inserted through the opening of the cervix, so that the catheter lies within the uterine cavity. A small balloon at the tip of the catheter is slowly inflated to stop fluid from leaking back out through the cervix during the test. The vaginal speculum is then removed, with the catheter remaining inside the uterus. A transvaginal ultrasound probe is inserted to conduct the internal scan through the vagina.

The FemVue device is then used to introduce a mixture of sterile saline and air bubbles through the catheter, allowing your physician to determine if your fallopian tubes are open or blocked. When the fallopian tubes are patent, a stream of glistening micro-bubbles will be easily seen traveling through the entire length of the fallopian tube on ultrasound. Most patients experience mild cramping during the procedure, but no pain.
