# Summary

Vaginal Birth After Caesarean section (VBAC) refers to the delivery method for pregnant women at 37 weeks or more of gestation who have previously had a single caesarean delivery. The success rate for VBAC typically ranges from 60-80%. Noteworthy risks include an increased chance of uterine rupture or requirement of caesarean section. Key contraindications include a classical caesarean scar, previous history of uterine rupture, or the typical contraindications to vaginal delivery like major placenta praevia.

- Increased risk of requiring caesarean section (failed VBAC)
