Effects of blood pressure on orbital and middle cerebral artery resistances in healthy pregnant women and women with preeclampsia

The object of the study was to test the hypothesis that preeclampsia leads to an abnormal vascular response to increasing blood pressure in cerebral vessels by analyzing the relationship between mean arterial pressure and resistance index in the central retinal, ophthalmic, and middle cerebral arter...

description: The object of the study was to test the hypothesis that preeclampsia leads to an abnormal vascular response to increasing blood pressure in cerebral vessels by analyzing the relationship between mean arterial pressure and resistance index in the central retinal, ophthalmic, and middle cerebral arteries in women with normal pregnancies and women with preeclampsia. Transcranial and color flow Doppler ultrasonographic studies were used to determine systolic, diastolic, and mean velocities and the resistance indexes in the central retinal, ophthalmic, and middle cerebral arteries in 24 women with normal pregnancies and 18 women with preeclampsia. In each group the relationship between the mean arterial pressure and the resistance index was determined for each artery by means of linear regression analysis. The Pearson correlation coefficients for each mean arterial pressure versus resistance index relationship were compared between the groups. In a separate analysis...
