PURPOSE: To explore the risk factors, ultrasonic manifestations, clinical features, and maternal and neonatal outcomes associated with complete uterine rupture.
BASIC PROCEDURES: All cases of complete uterine rupture diagnosed and treated in Jiangxi Maternal and Child Health Hospital from January 2012 to July 2018 were retrospectively analyzed. Risk factors, ultrasonic manifestations, clinical features, and maternal and infant outcomes were analyzed.
RESULT: All patients had a history of uterine surgery or induced abortion. Ultrasound examination revealed 15 cases of complete rupture of the uterus, five cases of missed diagnosis, three cases of misdiagnosis, and two cases of direct emergency operation without ultrasonography because of typical clinical manifestations and critical conditions. The clinical manifestations of 25 cases of uterine rupture varied from asymptomatic to clinical signs of "resting" rupture of the uterus to severe pain, hypotension, shock, and coma. All patients underwent surgical treatment, of which one case underwent DIC and died after rescue. The maternal mortality rate was 4% (1/25), the mortality rate of newborns (two pregnant women was twins) was 44% (12/27).
CONCLUSION: A history of uterine surgery is a major risk factor for uterine rupture. Attention should be paid not only to women who are pregnant again after cesarean section but also to those who have undergone other uterine operations (such as laparoscopic myomectomy, laparoscopic cornual pregnancy removal, etc.), delivery plans should be formulated accordingly. In cases of sudden abdominal pain during pregnancy or childbirth, the possibility of uterine rupture should be considered to achieve a timely and correct diagnosis and treatment.
