Dehiscence of cesarean section scar during pregnancy and delivery - Risk factors

Objective: We wanted to identify risk factors for dehiscence of cesarean section (CS) scars in patients undergoing repeated cesarean section. Material and methods: This was a retrospective case-control study over a 3-year period in our medical center (2011-2014), comparing women who had repeated CS without complications and women diagnosed with dehiscence. Data were collected from medical records and the groups were compared for demographic and obstetrical data. Results: Dehiscence was identified in 27 women, while 54 women without dehiscence were the control group. Statistically significant differences were found in the need for augmentation, the number of previous cesarean sections, cesarean section in the active phase of labor and length of hospitalization. Discussion: The need for augmentation of labor, CS in the nonactive stage and more than one cesarean section, all increased the risk of dehiscence. There was no association between dehiscence and scar pain, time elapsed since the previous cesarean section, the method of wound closure or fever.
