ABSTRACT
The spontaneous rupture of an unscarred uterus at 28 gestational weeks is an extremely rare event, particularly when associated with an intact amniotic sac extrusion and fetal leg entrapment, which has not been previously reported. A 27-year-old primigravid woman was referred to our department, due to perpetual abdominal pain, at 28 weeks and 5 days of gestation. The patient, G3p0, had previously undergone two induced abortions. At the time of admission, abdominal ultrasonography suggested a defect in the left uterine horn. An emergency laparotomy was subsequently performed and revealed an intact amniotic sac extrusion and fetal leg entrapment. Considering the risk of placental abruption, and the possibility of a secondary rupture if the gestation was not terminated, an emergency Cesarean section was recommended. Uterine rupture may be suspected whenever a patient complains of durative abdominal pain at 28 weeks and 5 days of gestation, even in the absence of an intra-abdominal hemorrhage or vaginal bleeding.
