BACKGROUND
Uterine rupture of an unscarred primigravid uterus is an exceedingly rare event. Cases of spontaneous rupture of an unscarred bicornuate uterus have been reported, but typically occur in the first or second trimester.
CASE
A 28-year-old primigravida at 37 weeks gestation with a known bicornuate uterus and no prior surgery underwent an emergent cesarean section after presenting with severe abdominal pain and signs of fetal compromise. She was found to have a uterine rupture with the fetus free in the abdomen accompanied by a large hemoperitoneum. Both mother and baby did well postoperatively.
CONCLUSION
Bicornuate uterus may be an independent risk factor for uterine rupture, which can occur in primigravid patients and at any gestation.
背景
未破裂的初产妇子宫发生子宫破裂是极为罕见的事件。曾有未破裂双角子宫自发性破裂的病例报道，但通常发生在妊娠早期或中期。
病例
一名28岁初产妇，妊娠37周，已知为双角子宫，既往无手术史，因出现严重腹痛及胎儿窘迫征象而接受急诊剖宫产。术中发现子宫破裂，胎儿位于腹腔内，伴有大量腹腔积血。母婴术后恢复良好。
结论
双角子宫可能是子宫破裂的独立危险因素，可发生于初产妇患者且在任何孕周。
