The association of pregnancy-induced hypertension and uterine malformations.

To evaluate the incidence of pregnancy-induced hypertension (PIH) in women with congenital uterine malformations, we examined the pregnancy complications of 67 women with uterine anomalies demonstrated by hysterosalpingography (HSG). The study group was compared with a control group of 130 women with normal-shaped uterus proven by HSG-matched for age, parity and presenting complaint. A significantly increased (p less than 0.04) rate of PIH was found for women with uterine malformation as well as a 2-fold higher frequency of preeclampsia. The etiology for this association is unknown, however; it is suggested that uterine malformation is a predisposing condition to PIH.
