Uterine rupture is least common with :
**Core Concept**
Uterine rupture is a life-threatening obstetric emergency characterized by spontaneous or traumatic disruption of the uterine wall, often leading to maternal and fetal morbidity and mortality. It is a rare but serious complication that can occur during pregnancy or labor, especially in women with a history of uterine surgery, previous uterine rupture, or certain medical conditions.
**Why the Correct Answer is Right**
The risk of uterine rupture is significantly lower in women who have undergone a cesarean section (CS) with a low transverse uterine incision, which is the most common type of CS. This is because the low transverse incision is designed to minimize the risk of uterine rupture in future pregnancies. The uterine scar from a low transverse CS is less likely to extend or rupture during labor, especially if the uterine incision is not too long or too high.
**Why Each Wrong Option is Incorrect**
* **Option B:** Women with a history of myomectomy (surgical removal of uterine fibroids) are at increased risk of uterine rupture, especially if the myomectomy was performed through a vertical uterine incision.
* **Option C:** Women with a history of previous uterine rupture are at high risk of recurrence, especially if the previous rupture was due to a vertical uterine incision.
* **Option D:** Women with a history of previous cesarean section with a classical or high vertical uterine incision are at increased risk of uterine rupture in future pregnancies, especially if the uterine incision is not too long or too high.
**Clinical Pearl / High-Yield Fact**
A key factor in reducing the risk of uterine rupture is the type of uterine incision used during a cesarean section. A low transverse uterine incision is associated with a significantly lower risk of uterine rupture compared to a classical or high vertical uterine incision.
**Correct Answer:** A.
