Uterine Scar Rupture - What Is a Uterine Rupture?

What is a uterine scar rupture?

A complete uterine scar rupture is a potentially life threatening condition for both the mother and/or the baby that requires immediate surgical intervention. Fortunately, uterine ruptures from a prior cesarean with a low-transverse scar is a rare event and occurs in less than 1% of women laboring for a VBAC (vaginal birth after caesarean). It is a tear through the thickness of the uterine wall at the site of a prior cesarean incision. The majority of cesarean uterine incisions are low-transverse. The scar form this type of incision is the least likely to rupture in a subsequent pregnancy, labor, and birth.
