Abstract
1-As cesarean rates are markedly increased specially in the last 20 years all over the world due to the development of safer surgical techniques and ancillary services (as blood typing and transfusion, antibiotic therapy), the national interest arose in reducing the rate of repeat cesarean, the leading indication for CD by allowing more and more trial for vaginal birth after cesarean.
2-The success rate of a TOL after Caesarean ranges between50% and 85%.In a study examining 1776 women undergoing TOL after Caesarean the overall success rate was 74%.ACanadian study reported similar results, quoting a success rate of 76.6%.
3-Discussions about vaginal delivery after prior CD first appeared in the literature in 1916. Cragin, who is attributed with coining the phrase “once a cesarean, always a cesarean,” described cases of women surviving vaginal birth after cesarean (VBAC). The National Institute of Child Health and Human Development (NICHD) convened a Consensus Development Conference in 1980 to assess why cesarean rates were rising and to determine whether CD resulted in improved fetal outcomes.
It was determined that TOL after prior low transverse cesarean posed low risk to fetus and mother. After 1980, VBAC rates rose. A series of highly publicized articles suggested that VBAC was associated with higher risks of uterine rupture and maternal and perinatal morbidity. As Most recent reports support the safety of VBAC in women with one cesarean as well as its cost effectiveness for the patients, her family and for heath care system, this make VBAC rates in a steady increase specially in women who had cesarean section due to breech presentation, fetal distress Pregnancy induced hypertension, ante partum hemorrhage and multiple gestation, these indications are often non-recurring and many of those women when become pregnant again there is no contraindications for attempting vaginal delivery.
4- the present study was designed to assess predictors of labor and show labor and perinatal outcome in women with one previous cesarean section admitted to Menoufiya University Hospital from April 2010 to April 2011.
