Caesarean scar ectopic pregnancy: a single centre case series

Area of Science:

• Reproductive Medicine
• Maternal-Fetal Medicine
• Gynecologic Surgery

Background:

• Caesarean scar pregnancy (CSP) is a rare but potentially life-threatening form of ectopic pregnancy.
• Increasing rates of caesarean deliveries may contribute to a rising incidence of CSP.
• Early and accurate diagnosis of CSP is crucial for effective management and prevention of complications.

Purpose of the Study:

• To analyze the clinical characteristics, diagnostic methods, management approaches, and outcomes of caesarean scar pregnancies (CSPs).
• To evaluate the effectiveness of different treatment modalities for CSP.
• To identify challenges in CSP diagnosis and management.

Main Methods:

• Retrospective cohort study analyzing 13 cases of CSP diagnosed between 2002 and 2007.
• Data collection involved institutional database interrogation and review of medical records and ultrasound images.
• Patient characteristics, management strategies, and pregnancy outcomes were extracted and analyzed.

Main Results:

• Thirteen CSP cases were identified, with a median maternal age of 34 years and median parity of 2.
• Vaginal bleeding was the most common symptom; ultrasound confirmed the diagnosis in 84.6% of cases, though diagnosis was delayed in 7 cases.
• Treatment varied, including systemic methotrexate (successful in 71.4% of cases), curettage, and hysterectomy; four women had subsequent successful pregnancies.

Conclusions:

• The diagnosis of caesarean scar pregnancy (CSP) can be difficult, necessitating increased clinical awareness due to its rising incidence.
• No clear association was found between the number of prior caesarean deliveries and CSP occurrence.
• Management strategies for CSP were inconsistent, primarily influenced by patient factors and available resources rather than specific CSP characteristics.
