Vaginal birth after cesarean section: management debate

Abstract

Obstetric performance of 1847 women with previous cesarean section (CS) during the years 1983 and 1984 were studied. Vaginal birth after cesarean section (VBAC) was attempted in 94% of females with one previous CS, 4% in those with two previous CS, and one among the 70 patients with three or more previous CS. VBAC was achieved in 51% of those with one previous CS. It was successful in 60% of parturients with CS for non-recurrent causes, 36% of CS for cephalopelvic disproportion (CPD) and in 64% of those with a prior vaginal delivery. Uterine scar dehiscence was found in 0.9% of all patients with a previous CS. A failed attempt with Ventouse to achieve VBAC caused maximum maternal and perinatal morbidity.
