PREECLAMPSIA : Clinical Characteristics and Pathogenesis - 08/09/11
Résumé |
Preeclampsia is defined as the triad of hypertension, proteinuria, and edema occurring after 20 weeks' gestation in a previously normotensive woman.18 It is a common disorder that complicates 5% to 10% of pregnancies and can progress to a life-threatening situation for both the mother and the fetus.
Preeclampsia is a multisystem disorder diagnosed by persistent blood pressure elevation to at least 140/90 mm Hg after 20 weeks' gestation in association with proteinuria and clinically evident, generalized edema. Proteinuria is defined as a urine protein concentration of 0.1 g/L or more in at least two random urine specimens collected 6 hours or more apart, or 0.3 g/L in a 24-hour collection. Preeclampsia is classified further into mild and severe. The criteria for severe preeclampsia are listed in Table 1. Eclampsia is the occurrence of convulsions in the absence of other causes.
