Placenta accreta is an abnormal adherence of the placenta to the uterine wall that can lead to significant maternal morbidity and mortality. The incidence of placenta accreta has increased 13-fold since the early 1900s and directly correlates with the increasing cesarean delivery rate. The prenatal diagnosis of placenta accreta by ultrasound along with risk factors including placenta previa and prior cesarean delivery can aid in delivery planning and improved outcomes. Referral to a tertiary care center and the use of a multidisciplinary care team is recommended.

Hypertension is commonly encountered in pregnancy and has both maternal and fetal effects. Acute hypertensive crisis most commonly occurs in severe preeclampsia and is associated with maternal stroke, cardiopulmonary decompensation, fetal decompensation due to decreased uterine perfusion, abruption, and stillbirth. Immediate stabilization of the mother including the use of intervenous antihypertensives is required and often delivery is indicated. With appropriate management, maternal and fetal outcomes can be excellent.
