We used two different noninvasive methods, i.e., transcranial Doppler velocimetry and magnetic resonance angiography to serially assess cerebrohemodynamics in a patient with postpartum eclampsia. Five hours after an eclamptic seizure, a decrease in mean velocity in both middle cerebral arteries and slight angiographical spasms indicated cerebral hypoperfusion. On hospital day 8, the patient showed an increase in the mean velocity of the middle cerebral artery, accompanied by significant vasospasms. Abnormal findings were not observed on hospital day 20. These combined methods are useful in assessing cerebrohemodynamics in eclampsia.
