Sonographically detected caesarean section scar defects and menstrual irregularity

Area of Science:

• Reproductive Medicine
• Medical Imaging

Background:

• Post-caesarean section scar defects (PCSD) are increasingly recognized.
• The clinical significance of these defects, particularly concerning menstrual bleeding, requires further investigation.

Purpose of the Study:

• To determine the frequency of post-caesarean section scar defects (PCSD) using transvaginal ultrasound.
• To correlate the presence and size of PCSD with abnormal menstrual bleeding patterns.

Main Methods:

• Retrospective review of pelvic ultrasound images from 318 women.
• Evaluation of 71 women with a history of caesarean section for hysterotomy incision defects.
• Correlation of ultrasound findings with patient-reported menstrual bleeding via questionnaire.

Main Results:

• A post-caesarean section scar defect (PCSD) was identified in 40% (29/71) of women with prior caesarean sections.
• The presence of PCSD was significantly associated with prolonged menstrual periods and post-menstrual spotting.
• A positive correlation was observed between the size of the PCSD and the severity of abnormal vaginal bleeding.

Conclusions:

• Transvaginal ultrasound can effectively detect post-caesarean section scar defects.
• PCSD are a common finding and are significantly associated with abnormal menstrual bleeding.
• The size of the scar defect appears to influence the degree of menstrual disturbance.
