It occurs if the mother is Rh negative and the baby is Rh positive, and a small amount of Rh positive ...
HELLP syndrome occurs in about 0.7% of pregnancies and affects about 15% of women with eclampsia or severe pre-eclampsia. [5] [2] Death of the mother is uncommon (< 1%). [1] [3] Outcomes in the babies are generally related to how premature they are at birth. [1] The syndrome was first named in 1982 by American gynaecologist Louis Weinstein. [2]
Preeclampsia is a complex condition of pregnancy involving hypertension and proteinuria usually after 20 weeks gestation. [68] It is associated with poor cytotrophoblastic invasion of the myometrium. Onset of the condition between 20 and 34 weeks gestation, is considered "early". [69]
Women who have chronic hypertension before their pregnancy are at increased risk of complications such as premature birth, low birthweight or stillbirth. [2] Women who have high blood pressure and had complications in their pregnancy have three times the risk of developing cardiovascular disease compared to women with normal blood pressure who ...
