Lower uterine segment pregnancy with placenta increta complicating first trimester induced abortion: diagnosis and conservative management

To discuss the diagnosis of and conservative management for lower uterine segment pregnancy with placenta increta complicating first trimester abortion. Four patients with previous caesarean section and severe hemorrhage in induced abortion in the first trimester were studied. Uterine artery embolization (UAE) was used to control bleeding and preserve the uterus. UAE controlled heavy uterine bleeding satisfactorily. One of the four patients asked for a hysterectomy after UAE, and her pathology report confirmed "lower uterine segment pregnancy with placenta increta". Previous caesarean section is a risk factor for lower uterine segment pregnancy with placenta increta. UAE is one of the best conservative management methods for heavy hemorrhage, especially for women who desire future fertility.
