title: Uterine rupture during pregnancy.
abstract: BACKGROUND
  Despite great advances in modern obstetrics, uterine rupture (UR) remains one of the most frightening complications with high morbidity and mortality.
  
  
  OBJECTIVE
  To improve the diagnosis and management of UR.
  
  
  RESULTS
  We report two cases of UR. Case 1 was spontaneous UR and case 2 was associated with a scar in the patient's uterus. Interestingly, the ruptured scar was not a scar from a previous cesarean section; it was a scar that was associated with placenta accreta. The fetal heart rates in both cases were below 80 beats per minute after UR. The newborn in case 1 died soon after delivery, while the newborn in case 2 survived. Both women were healthy and were discharged from hospital two to three weeks after surgery.
  
  
  CONCLUSIONS
  UR can occur in a previously unscarred uterus or from a scar of a cesarean section or scars caused by other pathologic lesions in the uterus. Severe fetal bradycardia might be a strong indicator for UR. Such study will help obstetricians provide more careful measures to manage UR, so that its morbidity and mortality can be decreased.
