Vacuum aspiration is a surgical procedure used to remove
molar pregnancy tissue from the uterus. This procedure
uses a hollow tube (cannula) that is attached by tubing to a bottle and a pump,
which provides a gentle vacuum.
cervix is opened, or dilated, the cannula is passed
into the uterus, the pump is turned on, and the molar tissue is gently removed
from the uterus. While suction is being applied, the wall of the uterus is
usually scraped with a sharp instrument, or curette, to remove the molar
You will be given
general anesthesia, so you are not awake during the procedure.
Medicine (such as oxytocin) is used
during or after the procedure to make the uterus contract. Uterine contractions
help the uterus shrink to its prepregnancy size and help stop uterine bleeding
after the growth is removed.
