[Pregnancy and delivery in patients with a personal history of cesarean section in Dakar: epidemiological, clinical, therapeutic and prognostic aspects].

The aim of our study was to determine hospitalization rate for vaginal birth after cesarean section in Pikine, to evaluate the quality of the management of pregnant women with previous cesarean section and to determine prognostic factors of the outcome of a trial of scar. We conducted a retrospective study based on medical records and operational protocols of patients who underwent vaginal birth after cesarean section over the period 1 January 2010 - 31 December 2011. We analyzed socio-demographic data, pregnancy follow-up, therapeutic modalities and prognosis. Data were collected and analyzed using Microsoft Office Excel 2007 software and SPSS software 17.0. The frequency of vaginal births after cesarean section was 9.6%. The average age of our patients was 29.4 years. Primiparous women accounted for 54%. Short spacing interval between births was found in 52.6% of cases. Based on the number of cesarean sections, the breakdown was as follows: patients with a history of one previous cesarean section (79.8%), patients with a history of two previous caesarean sections (17.9%) and patients with a history of three previous caesarean sections (2.3%). The number of antenatal consultations performed was greater than or equal to 3 in 79.8% of cases. Patients undergoing evacuation accounted for 54.2% and they were already in labor at the time of admission in 81.7% of cases. Trial of scar was authorized in 177 patients (34.3%) and, at the end of this test, 147 patients (83%) had vaginal birth, of whom 21.7% by vacuum extraction. Cesarean section was performed in 71.4% of cases with 245 emergency cesarean sections and 93 scheduled cesarean sections. A history of vaginal birth was a determining factor in normal delivery (p = 0.0001). There was also a significant relationship between mode of admission and decision to perform a cesarean section (p = 0.0001). Maternal mortality was 0.4%. Perinatal mortality rate was 28.2‰ of live births. We are witnessing a dramatic increase of deliveries after cesarean section in our SONUC Health Centre. The quality of management should be enhanced through a better strategy in preparation for delivery. Trial of scar is a procedure to encourage in order to reduce the rate of iterative cesarean sections.
