What is HSG – Hystero Salpingo Gram?
HSG Stands for Hystero Salpingo Gram. It is a procedure that looks at the inside of the uterus and fallopian tubes and the area around them. It is often done to assess the patency of the fallopian tubes of a woman.
During a HSG, a dye (contrast material) is put through a thin tube that is put through the vagina and into the uterus. Because the uterus and the fallopian tubes are hooked together, the dye will flow into the fallopian tubes. Pictures are taken using a steady beam of X-ray (fluoroscopy) as the dye passes through the uterus and fallopian tubes. The pictures can show problems such as an injury or abnormal structure of the uterus or fallopian tubes, or a blockage that would prevent an egg moving through a fallopian tube to the uterus. A blockage also could prevent sperm from moving into a fallopian tube and joining (fertilizing) an egg.
A HSG may also may find problems on the inside of the uterus that prevent a fertilized egg from attaching (implanting) to the uterine wall..
What are the benefits of HSG?
- It is a very basic diagnostic day procedure. Patient will get discharged from the hospital on the same day.
- The procedure is not expensive
- There are very minimal or no side effects
- HSG can be done under local anesthesia or under general anesthesia (GA). This depends on the patient’s decision which can be based on the cost and pain bearing capacity. HSG under GA can be painful in many cases.
Who needs HSG?
Doctors may suggest HSG as a diagnostic option as part of the standard infertility workup of a couple. If a laparoscopy or HSG has been done in the recent past (within 6 months) and if all reports are available, then the doctor may not recommend HSG.
What checks are needed before HSG?
The following processes have to be followed before a HSG Procedure
- Pre Anesthesia Checkup – If HSG is being done under GA, then the patient needs to be evaluated for suitability to administer anesthesia. For this, a PAC has to be done. This includes Chest X Ray, ECG, basic sugar tests and a few other blood investigations. Only if the anesthetist clears a patient in the PAC, the patient can proceed to HSG. This process is usually done a few days prior to the HSG procedure.
- In some cases, a physician may provide the clearance for anesthesia.
- Generally there are no other special preparations needed for this test. However, depending upon your diagnosis, you may need to take antibiotics to guard against possible infection. To ensure that you are not pregnant, the study is done between Day 7 and 10 of your cycle. Prior to the procedure you may take an anti-inflammatory medication.
