Accuracy of Prenatal Ultrasound in Determining the Uterine Scar Thickness
Background: To evaluate the accuracy of prenatal sonography in measurement of Caesarean section scar thickness and comparing the measurement with intraoperative visual assessment of uterine scar.
Methods: This was a comparative cross sectional study. It was conducted in the department of Gynecology and Obstetrics at Fatima Memorial Hospital, Lahore. Sonographic examination was performed in 90 pregnant patients with one previous Caesarean section, between 34 weeks and 40 weeks of gestation to assess
the scar thickness.
Results: The study showed that scar thickness of 2.5 mm or more, scar volume verified by 3-dimensional (3D) ultrasonography correlate with intraoperative finding of visual assessment of scar and risk of scar dehiscence.
Conclusion: Based on the obtained results we conclude that evaluation of scar by ultrasound and quality of the scar can be applied clinically and practically while deciding the mode of delivery in women who had previously given birth by Caesarean section.
