In rare cases, if an
oil-based dye is used, the oil can leak into the blood. This can cause blockage
of blood flow to a section of the lung (pulmonary embolism). Most hysterosalpingogram tests use water-based dyes.
After the test
After the test, some of the dye
will leak out of the vagina. You also may have some vaginal bleeding for
several days after the test. Call your doctor immediately if you have:
Heavy vaginal bleeding (soak more than one
tampon or pad in one hour).
Vaginal bleeding that lasts for more than 3 to 4 days.
The shape of the uterus and
fallopian tubes are normal. The fallopian tubes are not scarred or damaged. The
dye flows freely from the uterus, through the fallopian tubes, and spills
normally into the belly.
Fallopian tubes may be
scarred, malformed, or blocked so that the dye does not flow through the tubes
and spill into the belly. Possible causes of blocked fallopian tubes include
pelvic inflammatory disease (PID) or
The dye may leak through the
wall of the uterus, showing a tear or hole in the uterus.
An abnormal uterus may show
tissue (called a septum) that divides the uterus.
