Hypertension causing thrombotic microangiopathy (TMA) is one of the several etiologies of TMA, which causes endothelial damage and thrombosis of microvasculature, leading to hemolytic anemia, thrombocytopenia, and ischemic organ damage. Renal microvasculature involvement leading to renal dysfunction is most frequently seen in TMA but the degree of dysfunction varies with etiology. If left untreated, TMA carries a risk of high mortality, so it is extremely important for early identification of the cause of TMA. Plasma exchange is a commonly used treatment modality for TMA; however, it is not always necessary. Hypertension-induced TMA can be safely treated with antihypertensives, without the need for invasive plasma exchange. We report a 37-year-old African American hypertensive lady presenting with hypertensive emergency and TMA with rapidly progressing renal dysfunction. The patient had improvement in her platelet count after her blood pressure was reduced in a controlled manner.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
