Global variation and outcomes of expectant management of CSP.

The incidence of Cesarean scar pregnancies (CSPs) is rising globally. Ultrasound criteria for the diagnosis of CSPs have been described by the International Society of Ultrasound in obstetrics and gynecology and appear to be well used in various centers around the world. There is no guidance on best practices for expectant management of CSP, and there is considerable variation in how this is offered globally. Many studies have reported significant maternal morbidity in cases of CSP with fetal cardiac activity managed expectantly, largely relating to hemorrhage and cesarean hysterectomy from placenta accreta spectrum. However, high live birth rates are also reported. Literature describing the diagnosis and expectant management of CSP in low-resource settings is lacking. Expectant management in selected cases where no fetal cardiac activity is present is a reasonable option and can be associated with good maternal outcomes. Standardization in reporting different types of CSPs and correlating these with pregnancy outcomes will be an important next step in developing guidance for expectant management of this high-risk pregnancy with a high burden of complications.

Cesarean Scar Pregnancy: Patient Counseling and Management.

There is no universally agreed upon and adopted management protocol supported by professional societies in the United States or around the world for the treatment of cesarean scar pregnancy. There is a wide range of management options in the literature, and many of them can to lead to severe bleeding complications, which can result in loss of fertility or even maternal death. If inadequately managed, it can lead to untoward complications throughout all 3 trimesters of the pregnancy. Early detection of CSP has a paramount clinical importance.
