Manual Vacuum Aspiration (MVA)
Manual vacuum aspiration (MVA) is a safe and effective method of abortion that involves evacuation of the uterine contents by the use of a hand-held plastic aspirator. It is appropriate for treatment of incomplete abortion for uterine sizes up to 12 weeks from the last menstrual period (including miscarriage, spontaneous abortion and removal of retained products from an induced abortion), first-trimester abortion (menstrual regulation) and endometrial biopsy.
Compared to the sharp-curettage method of abortion, use of MVA requires less cervical dilatation and is associated with less blood loss, shorter hospital stays and a reduced need for anesthetic drugs. Vacuum aspiration methods (either manual or electric vacuum aspiration) are recommended over sharp curettage by the World Health Organization.
