Short\u2010term maternal and neonatal risks of classical caesarean sections (CCS) in the context of extreme prematurity remain unclear. The aim was to examine maternal and neonatal complications associated with CCSs versus low transverse caesarean sections (LTCS) at extremely preterm (23 0\/7\u201327 6\/7\u2009weeks) and very preterm gestational ages (28 0\/7\u201331 6\/7\u2009weeks).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A retrospective cohort study was conducted at Royal Brisbane and Womens Hospital, Queensland, Australia between 2016 and 2020.
