Low vertical uterine incision in caesarean section

Eleven of the 3,420 Caesarean sections performed in Westmead Hospital, Sydney during a 6-year period from 1979 to 1985 were by a low vertical uterine incision. All the others were the standard transverse lower segment operation except for 1 which was a postmortem classical Caesarean section. There are indications when the preferred lower segment Caesarean section with a transverse incision should be avoided in the interest of the mother and baby. A low vertical incision has more advantages and less dangers than a classical fundal incision. It is prudent to defer the decision regarding the type of incision until the uterus is inspected intraoperatively. If access to the lower uterine segment is limited by prematurity, an obstructing lesion, a transverse lie, or if the presenting part is high and difficulty in delivering the baby is anticipated, a low vertical incision should be considered.
