What is a hysterosalpingogram?
A hysterosalpingogram is a study to evaluate the uterine cavity and fallopian tubes. After sterile cleansing of the vaginal canal and exocervix, a cannula is placed in the external cervical os, and contrast material is injected under fluoroscopic guidance. The procedure is performed in women with primary or secondary infertility as well as in women with recurrent miscarriages. It is the best study to demonstrate patency of the fallopian tubes, and to see abnormalities in nondilated fallopian tubes. The study is performed on days 7 to 12 after the first day of the last menstrual period and should not be performed in the phase after ovulation, to prevent inadvertent harm to an unexpected pregnancy. The study is contraindicated in patients with symptoms or signs suggestive of acute pelvic infection.
