Vaginal birth after cesarean section: A retrospective study.

Byline: Masoome Ghafarzadeh, Mehrdad Namdari and Haleh Ashraf


Objective: The rising number of women undergoing elective repeat cesarean has been one of the principal reasons for the steady increase in the cesarean delivery rate. This study aim was to assess vaginal birth rates after cesarean (VBAC) in an educational hospital at Khorramabad, Lorestan.

Methodology: A retrospective analysis was performed on the obstetric data from medical records of 685 deliveries that underwent cesarean section in their previous delivery.

Results: VBAC rate among women with previous cesarean section was 10.4% (71 cases). The most frequent normal vaginal delivery was seen in women with a previous Kerr uterine incision (74.6%) and a history of one previous cesarean (69%).

Conclusions: VBAC delivery rate is low in our set up and proper counseling for trial of labor and evaluation of the cases of women with prior cesarean section has been considered a key method of reducing the cesarean section rate.

KEY WORDS: Vaginal birth after cesarean, Low segment cesarean section, Trial of labor.


Delivery rate by Cesarean section varies interna-tionally from 10-25%, and over last two decades vagi-nal birth has experienced considerable decline.1,2 A national study in the nineteen province of Iran in 1994 showed that the cesarean rate was 21% in governmental hospitals and 42% for non - governmental hospitals.3 Similar data in year 2000 showed an increase in cesarean rate to 27% and 58% for govern-mental and nongovernmental hospitals respectively.4 Previous Caesarean delivery is the most frequent indication for Caesarean section, and the stimulus for interest in vaginal birth after caesarean section is probably the solution for the progressive rise in the caesarean section rate.1,2

Vaginal birth rates after ce-sarean (VBAC) is usually safer for the mother than a repeat caesarean especially if the wish for an addi-tional pregnancy is estimated to be high, and al-though it does carry a very small risk of uterine rup-ture, the current guidelines state that this risk should neither dissuade women from choosing VBAC nor prevent service providers from offering trial of labor to women who choose this option. This study was carried out to determine the frequency of VBAC in our set up.


After being approved by the ethical committee of the university, we investigated the frequency of vaginal child birth in 685 deliveries of women with
