Introduction
Scar pregnancy embolization surgery carries significant risks and commonly causes massive vaginal bleeding; in some cases, uterine rupture may occur. If not promptly controlled and treated, it may severely impact the patient’s quality of life. Scar pregnancies typically occur in women with a prior history of cesarean delivery. During a subsequent pregnancy, the gestational sac implants at the site of the previous uterine scar. This procedure is associated with a risk of postoperative complications. It is recommended that patients seek treatment at a reputable hospital.
With the rising cesarean delivery rate, the incidence of cesarean scar pregnancy (CSP) has also increased. What are the risks associated with uterine artery embolization for cesarean scar pregnancy?
Risks of Uterine Artery Embolization for Cesarean Scar Pregnancy
Uterine artery embolization for CSP carries significant risks, commonly including massive vaginal bleeding and, in some cases, uterine rupture. If not promptly controlled and treated, these complications may severely impact the patient’s quality of life. CSP typically occurs in women with a prior history of cesarean delivery. During a subsequent pregnancy, the gestational sac implants at the site of the previous uterine scar. Such procedures carry inherent risks of postoperative complications. It is strongly recommended that patients seek treatment at reputable hospitals to avoid adverse outcomes.
“Scar” refers to the uterine scar resulting from a prior cesarean delivery. In a second pregnancy, implantation of the gestational sac at this pre-existing scar site often leads to vaginal bleeding and, subsequently, uterine rupture. The associated risks are comparable to those of ectopic pregnancy and represent one of the most challenging clinical dilemmas faced by obstetricians and gynecologists. Termination of pregnancy in CSP—commonly referred to as “scar pregnancy abortion”—is a surgical intervention specifically designed for CSP management. Abortion in women with a scarred uterus carries relatively high risks. Interventional surgical approaches—including intra-arterial administration of chemotherapeutic agents—or systemic chemotherapy to terminate the embryo are viable options.
Following 48 hours of medical treatment, transvaginal ultrasound-guided curettage can be performed, transforming an otherwise “blind” procedure into a “vision-guided” one—thereby substantially reducing the risks of uterine perforation and incomplete evacuation. Postoperative outcomes are generally satisfactory. After surgery, patients should avoid spicy and irritating foods and instead consume bland, easily digestible meals. We hope this information proves helpful. Wishing you good health and happiness!
