An advocate claims that the American College of Obstetricians & Gynecologists (ACOG) said VBAC after more than one prior cesarean (VBAMC) doesn’t pose an increased risk. A reader contacted me asking if this was correct. It is not. ACOG does not say that because it’s not true.
Having a prior uterine surgery increases the risk of uterine rupture. The relative risk is still low, but it’s there. Other factors can push that risk higher (such as induction.) But sometimes there is no “reason” for a uterine rupture other than a prior cesarean. Uterine rupture stories illustrate that even though the risk is ~ 0.4% (among those with one prior low transverse cesarean in a spontaneously laboring VBAC), that small number impacts real parents & babies.
A VBAC study out of Canada reported, “Absolute rates of severe maternal morbidity and mortality were low but significantly higher after attempted vaginal birth after cesarean delivery compared with elective repeat cesarean delivery.” After reading the abstract, and full text, I could quickly see how this study will be misinterpreted by many, so let me walk you through it.
