Abstract
BACKGROUND: Uterine rupture is a rare, life-threatening event in obstetrics that may be fatal for the mother and fetus. Therefore, obstetricians need to pay attention to and should consider the antenatal diagnosis of uterine rupture in women having its risk factors. Successful conservative management for asymptomatic uterine rupture due to previous laparoscopic surgery for interstitial pregnancy has already been reported but remains understudied. CASE PRESENTATION: A 39-year-old woman was diagnosed asymptomatic uterine rupture at 22 weeks gestation by a routine second-trimester ultrasound scan. She had a history of laparoscopic salpingectomy with cornual wedge resection for interstitial pregnancy 10 months before this pregnancy. Refusing doctor's twice advice of terminating the pregnancy, the patient insisted carrying on the pregnancy, and followed up by ultrasound and magnetic resonance imaging. Fetal growth was appropriate, fetal movements were good and the patient had no symptoms, without uterine contraction or amniotic fluid loss throughout follow-up period. Caesarean section was carried out at 34 + 1 weeks with a good maternal and neonatal outcome. CONCLUSIONS: A previous history of laparoscopic salpingectomy with cornual wedge resection could be a risk factor for uterine rupture in pregnant women. Sonographers should be alert to this potential risk in pregnant women with a history of laparoscopic salpingectomy with cornual wedge resection even in asymptomatic patients.
