Outcome of Vaginal Birth After Cesarean Section (VBAC)

Generally, it is agreed that all women who previously had a cesarean section should be attempted for normal vaginal delivery. Of course, post-cesarean normal vaginal delivery is associated with potential risks and is sometimes clinically indicative of recurrent cesarean section.

This study aimed to evaluate the success and complications of vaginal birth after a cesarean section in pregnant women referred to Ali Ibn Abi Talib Hospital in Zahedan in 2016 - 17.

The present descriptive-analytical study was carried out after the approval of the Student Ethics Committee by visiting the archive of Ali Ibn Abi Talib Hospital in Zahedan to review the hospital records of women admitted to the gynecological ward for vaginal birth after a cesarean section. The researcher abstracted data into predetermined checklists. Finally, SPSS software was used for data analysis.

In this study, 176 patients were evaluated. The mean gestational age was 37.64±3.13 weeks. The success rate of vaginal birth after one cesarean section was 92% (162 patients), and the failure rate was 8% (14 patients). Also, the complications of vaginal birth after cesarean section were transfusion (n = 4, 2.3%), cervical rupture (n = 3, 1.7%), neonatal death (n = 4, 1.7%), and uterine rupture (n = 1, 6%) (P = 0.0).

In the present study, the success rate of vaginal birth after one cesarean section was 92% (162 patients), and the failure rate was 8% (14 patients). Complications included blood transfusion with 2.3%, cervical rupture with 1.7%, infant mortality with 1.7%, and uterine rupture with 0.6%.
