Background: Patients with previous caesarean section now represent a relatively large proportion of the obstetric population. The main aim of the study is to evaluate the accuracy of transvaginal ultrasound in evaluation of lower uterine segment caesarean scar integrity and predicting scar dehiscence
Materials and Methods: The study included 144 patients based on the inclusion and exclusion criteria. All the patients demographic and previous delivery history was noted. Study procedure was explained to the patients in their understandable language and informed consent was obtained. All the patients were subjected to trans vaginal ultrasound to evaluate the scar integrity and dehiscence. The data was analysed by SPSS (16.0) version.
Results: Total 144 patients were analysed. Maximum patients had Fetal distress for previous LSCS indication. Based on the scar size they were divided into two groups group-I (>3/=3mm) and group-II (<3 mm). 96 were included in the group-I and 54 in group-II. Group-I maximum patients showed VBAC (38), 25 SVD and 13 AVD. 16 patients went for emergency LSCS in that 5 showed foetal distress and 11 had scar tenderness. 42 patients undergone elective LSCS in this 4 showed thinned out scar. VBAC (1) and CS (44) in group-II and 15 patients underwent emergency LSCS. 12 showed scar tenderness and 1 had foetal distress. 5 patients showed thinner out scar under gone emergency LSCS in group-II. 25 patients showed thinned out scar in group-II undergone elective surgery.
Conclusion: Previous LSCS scar evaluation by transvaginal sonography improves the labour outcome and lower the complications during the surgery.
