Abstract：
:Preeclampsia has traditionally been viewed as one of several forms of hypertension complicating pregnancy. More recently, the multisystem nature of this unique gestational disorder has been emphasized. Pathophysiologic events, including abnormal placentation and heightened vascular reactivity, may occur weeks or months prior to clinical recognition of the disease. Although most frequently presenting as hypertension and proteinuria, hepatic (abdominal pain and elevation of transaminases) and hematologic (intravascular hemolysis and thrombocytopenia) involvement may be important features of the disease. Current theories suggest that multiorgan dysfunction may be caused by widespread vascular endothelial dysfunction, vasospasm, and variable activation of coagulation mechanisms. Pending delivery, which is the only definitive therapy for preeclampsia, maternal complications of intracerebral hemorrhage and eclampsia may be prevented with judicious use of antihypertensive medication (e.g., hydralazine) and magnesium sulfate, respectively. Finally, data from a number of small trials suggest that low-dose aspirin (60-100 mg/d) may reduce the incidence of preeclampsia in patients at high risk without adversely affecting the fetus or newborn; however, it is recommended that aspirin not be used as a routine prophylactic intervention until publication of results of several ongoing large multicenter trials, which will help to more fully clarify the benefits and risks of this approach.
