Introduction
Cesarean scar pregnancy (CSP) carries certain surgical risks. CSP refers to implantation of the fertilized ovum at the site of a previous cesarean scar. It is typically managed by induced abortion. Continuing the pregnancy is not recommended, as CSP poses a very high risk of uterine rupture in the pregnant woman. As gestational age advances and the embryo continues to grow, the associated risks progressively increase; therefore, prompt surgical intervention is strongly advised.
If a woman’s first delivery is by cesarean section, it is generally recommended to wait at least three years before attempting a second pregnancy. A shorter interval significantly increases the risk of cesarean scar pregnancy (CSP). Is surgical management of CSP associated with high risk?
Is surgical management of cesarean scar pregnancy high-risk?
Surgical management of CSP carries definite risks. CSP refers to implantation of the fertilized ovum within the uterine scar from a prior cesarean delivery. Termination of pregnancy via induced abortion is typically required in such cases, and continuation of the pregnancy is strongly discouraged. CSP poses extremely high risks, particularly for uterine rupture. As gestational age advances and the embryo continues to grow, the associated dangers escalate progressively. Prompt surgical intervention is therefore advised.
Due to the thin myometrium of the uterine isthmus and the diminished contractility of the cesarean scar tissue, blood vessels ruptured during surgical intervention cannot constrict and close spontaneously—potentially resulting in life-threatening hemorrhage. Thus, comprehensive preoperative auxiliary examinations are mandatory. Treatment strategies are individualized, as the prognosis for most CSP cases—particularly those involving the cesarean scar—is poor. Once diagnosed, termination of pregnancy is strongly recommended. Therapeutic options include medical and surgical approaches, with methotrexate being the first-line pharmacological agent. Surgical interventions may include ultrasound-guided dilation and curettage (D&C) or hysteroscopic resection of the cesarean scar, selected according to the patient’s clinical condition. Uterine artery embolization (UAE) serves as an important adjunctive treatment modality.
Postoperatively, adequate rest and enhanced nutritional intake are essential to support recovery. In general, women are advised against conceiving again within two to three years following cesarean delivery; pregnancy may be considered after a minimum interval of three years.
