Why Does a Classical C-section Carry a Ten Percent Risk of Uterine Rupture During Labor?

A uterine rupture is an emergency and a surgical emergency. Surgery on the uterus from big fibroid removal or a prior classical C-section cuts through the musculature of the uterus. The type of incision from a classical C-section is much more likely to rupture during labor with a risk of like ten percent. Ten percent risk is too high so the group should not labor.

A low transverse C-section is preferred in term patients where it is almost always possible. Delivery of a preterm baby is one of the most common reasons for a classical C-section. The uterus has not expanded enough and the lower uterine segment is not developed. An incision in the lower part of the uterine segment may not safely deliver the preterm baby. A classical C-section is also chosen for surgical complexity when patients have had multiple C-sections and scar tissue prevents access.
