What is Hysterosalpingography for?

What is Hysterosalpingography for?

Hysterosalpingography, or HSG, is an X-ray test to outline the internal shape of the uterus and show whether the fallopian tubes are blocked. In HSG, a thin tube is threaded through the vagina and cervix.

When should a Hysterosalpingography examination be performed?

The exam should take place between 7-10 days after the beginning of your last menstrual period. A course of antibiotics may be prescribed prior to the test depending on your referring provider’s recommendations.

How do you test for Hysterosalpingography?

An HSG test is usually done in a radiology lab and takes between 10 and 30 minutes. Your doctor will insert a speculum into your vagina (like when you have a Pap smear), and then place a thin plastic tube inside your cervix that will lead to your uterus and fallopian tubes.

What imaging modality is used in Hysterosalpingography?

Despite recent advances in various imaging modalities to assess the fallopian tubes such as a three-dimensional dynamic magnetic resonance hysterosalpingography (3D dMR-HSG) and contrast enhanced hystero-salpingo-sonography, conventional HSG still remains the imaging modality of choice [2].

Which tools are used to perform a hysterosalpingogram?

Instruments required for hysterosalpingogram (HSG) include an open-sided speculum, tenaculum, sponge stick, antiseptic, contrast medium, and an acorn (Cohen) cannula (A) or a balloon-tip catheter (B).

What is normal hysterosalpingogram?

A hysterosalpingogram or HSG is an x-ray procedure used to see whether the fallopian tubes are patent (open) and if the inside of the uterus (uterine cavity) is normal. HSG is an outpatient procedure that usually takes less than 5 minutes to perform.

What happens after HSG test?

A small amount of spotting is normal after an HSG test, and there can also be leakage of the contrast dye. Wearing a pad for the rest of the day will help protect your clothing. You may need to wear a pad for a few days as the dye is slowly expelled from the uterus.

What dye is used for HSG?

What is contrast Dye Used during HSG? The HSG contrast dye is an iodine-based fluid that makes your uterus and fallopian tubes visible on the x-ray image.

Why is iodinated contrast used in hysterosalpingogram?

Iodinated contrast is injected into the uterine cavity through the cervix, allowing the uterine cavity and fallopian tubes to be evaluated. It accurately defines the size and shape of the uterine cavity and assesses whether the fallopian tubes are patent (1, 2).

How painful is HSG?

Mild pain or discomfort is common with an HSG, both during the procedure and afterward. You may feel cramping when your provider inserts the dye solution into your uterus. You may experience more cramping when your tubes are blocked. The cramping may last anywhere from five minutes after your procedure to a few hours.

What contrast media is used in Hysterosalpingography?

Both oil-based and water-based iodinated contrasts are used for HSG. The advantages and disadvantages of each have been debated for years. Most studies ultimately fail to show a difference in the diagnostic accuracy of uterine or tubal pathology with either of these media.

Why is iodinated contrast used in Hysterosalpingogram?

Can HSG cause miscarriage?

HSG should never be performed on a pregnant woman as the procedure and x-ray exposure can lead to serious complications or miscarriage.

Are HSG tests painful?

Mild pain or discomfort is common with an HSG, both during the procedure and afterward. You may feel cramping when your provider inserts the dye solution into your uterus. You may experience more cramping when your tubes are blocked.

Do you bleed after HSG test?

Vaginal spotting commonly occurs for 1 to 2 days after HSG. Unless otherwise instructed, you should notify your doctor if you experience heavy bleeding after HSG.

When is ionic contrast media used?

Iodinated contrast media are contrast agents that contain iodine atoms used for x-ray-based imaging modalities such as computed tomography (CT). They can also used in fluoroscopy, angiography and venography, and even occasionally, plain radiography.

What is hysterosalpingography HSG?

Hysterosalpingography (HSG) refers to the radiographic evaluation of the uterine cavity and fallopian tubes after injection of a radio-opaque contrast medium through the cervical canal. It is commonly and the initial investigation for evaluating fallopian tube disorders associated with infertility [1].

How effective is oil-based contrast for hysterosalpingography?

When oil-based contrast is used rates of pregnancy increase by about 10% compared to water-based contrast. A meta-analysis revealed 3.6 times greater odds (OR = 3.6) of pregnancy with oil-based contrast compared to no hysterosalpingography.

What is HSG X-ray?

HSG is an x-ray exam of the uterus and fallopian tubes. It uses a special form of x-ray called fluoroscopy and a contrast material. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

What is the role of HSG in infertility treatment?

HSG is considered a diagnostic procedure, but may also have therapeutic benefits for infertility treatment. When oil-based contrast is used rates of pregnancy increase by about 10% compared to water-based contrast. A meta-analysis revealed 3.6 times greater odds (OR = 3.6) of pregnancy with oil-based contrast compared to no hysterosalpingography.
