Results:
During the study period, 3141 eligible births were identified, of which
422 were excluded in accordance with our exclusion criteria. According
to our study inclusion criteria, all parturients with previous 2 CD
experienced a previous vaginal delivery. Of the remaining 2719
deliveries, 485 (17.8%) parturients attempted TOLAC and the remaining
2234 (82.2%) had a scheduled elective repeat CD. (Figure 1) .
Among the 485 parturients attempting TOLAC, 418 achieved vaginal
delivery (86.2%), with 26 (26/418, 6.2%) assisted by operative VD. The
remaining 13.8% experienced failed TOLAC and required in labor CD.
Table 1 displays various demographic and obstetrical
characteristics of the study groups. Parturients who had requested an
elective repeat CD were significantly younger and of lower gravidity and
parity order. In addition, they had higher rates of conception using
advanced reproductive technology, diabetes (pre-gestational and
gestational) and hypertensive disorders of pregnancy.
