Uterine rupture in the non-laboring uterus is a rare occurrence, which can lead to significant morbidity and mortality for the mother and fetus. Management of this presentation is complex at pre-viable gestations.
A 35 year old primigravid woman with multiple previous myomectomies presented with spontaneous complete thickness uterine rupture at 21 weeks gestation. A 10 cm myometrial defect and iatrogenic amniotomy were surgically corrected with fetal preservation. This led to pregnancy continuation to 32 weeks gestation when elective cesarean delivery resulted in excellent neonatal outcome.
Early surgical diagnosis, multidisciplinary team approach, iatrogenic amniotomy and continuous two-layer myometrial closure were factors that contributed to pregnancy prolongation in this large myometrial rupture.
