Retrospective study to find predictive factors of scar dehiscence in previous caesarean section to prevent maternal and perinatal morbidity and mortality

Background Uterine scar dehiscence is a complication in which scar tissue remaining from previous C-section is disrupted and separated. Its incidence ranges between 0.2%-4.3% of all pregnancies with previous caesarean. It is asymptomatic in 48% of patients and thus is a serious complication because if not predicted it can lead to uterine rupture.

Methods Patients included in the study were of previous caesarean who were taken for repeat caesarean and scar dehiscence was not predicted preoperatively but seen intra-operatively. History, symptoms, signs and radiological investigations were interpreted to find out single or multiple factors responsible for scar dehiscence.

Results Incidence of scar dehiscence was found to be 8.3% .Scar dehiscence was detected in 55% of cases who were gravida 3 and above, all patients with intraoperative scar tenderness, 35% of patients with scar thickness ˂2mm, 70% cases with POG 37-40 weeks, 65% of patients with interpregnancy interval˂18 months,86.6% of patients with scar dehiscence had baby birth weight ˃3kg.

Conclusions Authors concluded that a single factor which has maximum predictive value for scar dehiscence is scar tenderness.
