Abstract:

Uterine rupture is a critical obstetric emergency characterized by sudden onset, rapid progression, and high maternal-fetal mortality. While the most common predisposing factor is a scarred uterus, spontaneous uterine and ovarian rupture in late pregnancy without prior surgical history is exceedingly rare. This report describes the diagnosis and management of a non-scarred uterine pregnancy with concurrent uterine and ovarian rupture in an advanced-age patient. The case highlights unique mechanisms of rupture in non-scarred uteri, including advanced maternal age, history of ankylosing spondylitis, and long-term glucocorticoid use, all of which may compromise uterine myometrial integrity. Early diagnosis and immediate intervention were pivotal in improving outcomes, underscoring the importance of multidisciplinary collaboration in emergency obstetric care. This case provides clinical insights into early risk stratification and optimal management of non-scarred uterine rupture to prevent adverse pregnancy outcomes.
