In addition, when compared with the control group, women with a history of HA were at a higher risk of placental risks (P less then 0.05), such as placenta previa (11.6% versus 3.1%), abnormally invasive placenta (AIP) (33.56% versus 2.7%), and retained placenta (42.5% versus 8.6%). This resulted in a significantly higher postpartum hemorrhage (PPH) rate in the study group as compared with that in the control group (8.9% versus 1.0%, P less then 0.05). Such cases were more likely to be found in patients with severe IUA compared with those who were assessed as mild and moderate. Conclusions The history of HA might be an important risk factor inducing placental problems and PPH in the third trimester. More attention should be paid to the labor of pregnant women with a history of HA. 2020 Annals of Translational Medicine.

There is also no consensus on the method of how to deal with the scar tissue on the surface of the intrauterine cavity. Methods From January 2016 to October 2017, 179 patients who had HA met the enrollment criteria (see the text below), and their data were analyzed retrospectively. In addition, all patients were divided into three groups according to the surgical techniques used. The groups were the ploughing group (PG) (using cold scissors to dissect the adhesion and cut the scar tissue using a ploughing technique) (n=81), the traditional group (TG) (using cold scissors to dissect the adhesion, but not deal with the scar tissue) (n=42), and the electrosurgical group (EG) (using a resectoscope to dissect the adhesion with an energy L-hook electrode, and not deal with the scar tissue) (n=56).
