Case series of uterine rupture and subsequent pregnancy outcome

Objective-To review the incidence of ruptured uterus at Women's Hospital, Hamad Medical Corporation (HMC), highlight the management approach of suture repair in relation to maintaining the patient's future fertility, and study subsequent pregnancy outcome and the risk: of recurrent uterine rupture. Methods-Case notes were reviewed for every patient with a ruptured uterus at the Women's Hospital in Doha for a period of 15 years, from 1 January 1983 to 31 December 1997. Results-There were 17 cases of ruptured uterus. The incidence of ruptured uterus was calculated to be 0.012%; eight (47%) of these occurred in patients with previous cesarean scars, while nine cases (52.9%) were grand multiparas (5 or more). In nine cases (52.9%), uterine rupture was associated with oxytocin use, and four patients (23.5%) were associated with prostaglandin E2 (PGE2) use. The ruptures occurred in the posterior uterine wall in one patient, the scar of a classical cesarean section in another, and in the lower segment in the remainder. Fetal heart abnormalities were observed in all cases in which the uterus ruptured during labor. Abdominal hysterectomy was performed in eight cases (47%). The remaining nine patients had suture repair, two with sterilization, and the other seven without sterilization. Six of these subsequently became pregnant, for a total of ten babies, all delivered by cesarean section. Conclusion-Even though rupture of the uterus was rare in our study, its occurrence should be suspected when there are sudden fetal heart abnormalities during labor or unexpected antepartum or postparum hemorrhage. Suture repair should be considered whenever possible to maintain the patient's future fertility.
