Prediction of Symptomatic Vasospasm after Subarachnoid Hemorrhage by Transcran Doppler & Cerebral Blood Flow Changes
Stroke 23:674-679, Grosset,D.G.,et al, 1992
See this aricle in Pubmed

Article Abstract
Ten of 15 patients studied before the onset of any deficit subsequently developed a focal neurological abnormality.In 14 of 15 patients,and in a further five in which single-photon emission computed tomography was performed after the onset of a delayed neurological deficit,perfusion patterns were abnormal and correlated with sites of increased Doppler velocities.Four patients had zones of cerebral hypoperfusion but did not develop neurological deficit.Conclusions:Transcranial Doppler measurements can assist in identifying patients at risk of delayed ischemic deficit. Selection of patients for regional cerebral blood flow mapping studies and for prophylactic anti-ischemic therapy may be considered on this basis.
