Hypertension affects approximately 10% of pregnancies and may persist in the postpartum period. Furthermore, de novo hypertension may present after delivery, but its exact prevalence is not verified. Both types of hypertension expose the mother to eventually severe complications like eclampsia, stroke, pulmonary edema, and HELLP (hemolysis, elevated liver enzymes, low platelet) syndrome.Until today, there are limited data regarding the risk factors, pathogenesis, and pathophysiology of postpartum hypertensive disorders. However, there is certain evidence that preeclampsia may in large part be responsible. Women who experienced preeclampsia during pregnancy, although considered cured after delivery and elimination of the placenta, continue to present endothelial and renal dysfunction in the postpartum period. The brain and kidneys are particularly sensitive to this pathological vascular condition, and severe complications may result from their involvement. Large randomized trials are needed to give us the evidence that will allow a timely diagnosis and treatment. Until then, medical providers should increase their knowledge regarding hypertension after delivery because many times there is an underestimation of the complications that can ensue after a misdiagnosed or undertreated postpartum hypertension. |
