Abstract

Angular pregnancy refers to implantation of the embryo just medial to uterotubal junction in the lateral angle of the uterine cavity. This is differentiated from interstitial pregnancy in which the gestational sac is located within intramural portion of the tube. Angular pregnancy is categorized as intrauterine pregnancy and the outcome is known favorable. However, there have been few reports about adverse perinatal complications such as abortion, retained placenta, placenta accreta, placenta percreta and uterine rupture. We report a case of angular pregnancy complicated with preterm labor at 25 gestational weeks, placenta accreta and postpartum endometritis. This case suggests that angular pregnancy should be differentiated from normal intrauterine pregnancy because of its potential risk of adverse outcome.

Keywords: Angular pregnancy, Premature obstetric labor, Placenta accreta, Postpartum endometritis

Figures and Tables

Fig. 1

Anterior view of uterus after baby out during cesarean section: Protrusion of left uterine angle is noted. The inner side of this gestational swelling was connected with uterine cavity.

Fig. 2

CT scan shows 4.5 cm sized intrauterine hematoma deviated to the left uterine angle. The myometrial wall of left uterine cornus is very thin compared with right uterine angle (Left: sagittal view, Right: axial view).
