About

Abortion is considered the most common cause of fetal demise all over the world. The majority of cases occur in the first trimester. The termination of abortion may be by medical or surgical methods, however; the surgical methods represent the greater part of termination. Therefore, the safety of this procedure is a worldwide public health concern. Many clinical studies have reported the safety of surgical evacuation in the first trimester.

The suction-aspiration or vacuum aspiration is the most common surgical method of induced abortion. This consists of removing the fetus, embryo, placenta, and membranes by suction using a manual syringe or electric pump. However; these techniques always need cervical dilation before aspiration. The menstrual extraction does not require cervical dilation and can be used in very early pregnancy.
