Vacuum Aspiration - Complications

Complications

When used for uterine evacuation, vacuum aspiration is 98% effective in removing all uterine contents. Retained products of conception require a second aspiration procedure. This is more common when the procedure is performed very early in pregnancy, before 6 weeks gestational age.

Other complications occur at a rate of less than 1 per 100 procedures and include excessive blood loss, infection, injury to the cervix or uterus, including perforation, and uterine adhesions.
