Discussion of Uterine rupture
- Most common cause of uterine rupture is old cesarean scars.
- Uterine rupture may be limited to dehiscence of the ends of the cesarean scar with an intact overlying serosal layer.
- Full-thickness uterine rupture, with direct communication of the uterine and peritoneal cavities, results in massive hemoperitoneum and carries high fetal and maternal morbidity and mortality rates.
- Classic scars are more likely to rupture before labor, whereas lower uterine segment scars tend to rupture after labor.
 Imaging Findings for Uterine rupture
- Reported sonographic signs of uterine rupture include the identification of the protruding portion of the amniotic sac, an endometrial or myometrial defect, an extrauterine hematoma, and hemoperitoneum.
- Multiplanar MR imaging offers a comprehensive assessment of the uterine wall and the peritoneal cavity.
