Scarred uterus 0.09 means the thickness of the scar of the uterus is 0.09cm, which is relatively thin and cannot withstand the pressure caused by contractions during normal delivery, and it is easy to cause uterine rupture, and the success rate of normal delivery is low, so normal delivery is not recommended. The ability to have a normal delivery depends on the elasticity of the scar, the size of the fetus, the pelvis, the condition of the birth canal and other factors. If the scar is well recovered and the elasticity of the scar is good, the pregnant woman can also try to have a normal delivery, but before the normal delivery, she must complete a series of examinations to evaluate the size of the fetus, the pelvis and the conditions of the birth canal, and then decide whether to have a normal delivery. Secondly, if the scar is not recovered well, and the elasticity of the scar is poor, the fetus is huge or the pelvic condition is abnormal, then it is easy to have complications such as uterine rupture, placental rupture and placental abruption, which will endanger the health of the pregnant woman and the fetus during the normal delivery. Therefore, for pregnant women with a scarred uterus of 0.09cm, it is important to follow the doctor’s instructions and improve all examinations to ensure the health of the pregnant woman and the fetus.
