Abstract

Uterine rupture is an obstetrical emergency that can be catastrophic for the mother and fetus. Previous uterine surgery, including previous cesarean delivery or myomectomy, is an established risk factor, although the exact magnitude of the associated risk remains uncertain. We reviewed the literature related to uterine rupture after previous cesarean delivery with classical incision or myomectomy in an attempt to quantify outcomes associated with various management strategies. Although cesarean delivery with a classical incision is relatively uncommon (representing 0.3%-0.4% of deliveries), it presents a significant risk of rupture in subsequent pregnancies (1%-12% on the basis of published reports). Available data suggest that scheduled cesarean at 36-37 weeks optimizes both maternal and fetal outcomes in these cases. Patients with previous myomectomy are more frequently encountered in the obstetrical population. The risk of uterine rupture in subsequent pregnancies in these women is substantially lower than those with a history of previous classical incision (0.5%-0.7% on the basis of published reports). Although less common, given the potentially devastating consequences of uterine rupture, scheduled delivery at 38 weeks is suggested in those women requiring cesarean delivery. Despite the lack of well-controlled studies, preferred management strategies can be gleaned from previously published data to optimize maternal and fetal outcomes in women with these risk factors.
