Cesarean Scar Pregnancy: A Systematic Review

Area of Science:

• Reproductive Medicine
• Obstetrics and Gynecology
• Medical Imaging

Background:

• Cesarean scar pregnancy (CSP) is an emerging ectopic pregnancy type associated with rising cesarean delivery rates and improved diagnostic imaging.
• CSP presents as two types: Type I (endogenic) involving progression into the cervicoisthmic space or uterine cavity, and Type II (exogenic) with deep scar invasion toward the bladder or abdominal cavity.
• Type I CSP may lead to viable pregnancies but carries a high risk of placental site bleeding, while Type II is prone to early uterine rupture and hemorrhage.

Purpose of the Study:

• To highlight the significance of early diagnosis and management of cesarean scar pregnancy.
• To differentiate between the two types of CSP and their associated complications.
• To emphasize the need for individualized treatment strategies due to limited evidence-based guidelines.

Main Methods:

• Review of current literature and clinical understanding of cesarean scar pregnancy.
• Discussion of diagnostic modalities, primarily ultrasound and Doppler imaging.
• Analysis of the clinical presentation, hCG levels, imaging features, and surgical expertise in treatment decisions.

Main Results:

• Cesarean scar pregnancy (CSP) is classified into endogenic (Type I) and exogenic (Type II) forms, each with distinct clinical implications and risks.
• Early first-trimester screening is recommended for pregnant women with a history of cesarean delivery.
• Diagnosis relies on ultrasound and Doppler imaging, though evidence-based management guidelines are still developing.

Conclusions:

• Early detection of cesarean scar pregnancy is critical for optimal patient outcomes.
• Treatment for CSP requires a personalized approach, considering patient-specific factors and clinical findings.
• Further research, including randomized studies, is needed to establish clear evidence-based management protocols for CSP.
