The purpose of this study was to measure the correlation between CBF and the middle cerebral artery (MCA) and basilar artery (BA) flow velocities, as measured by TCD during excessive hemodynamic changes produced by hypertension and hypotension in adult dogs. The peak, diastolic, and mean flow velocities were measured by TCD. Arterial hypertension was induced by administration of dopamine at 5 and 15 microg/kg/min, and hypotension was induced by hemorrhage. During the hemodynamic changes, the BA velocity correlated more closely with the alteration in the CBF than the MCA velocity. In terms of percentages of the values during anesthesia, there was good correlation between CBF and the MCA and BA velocities. In conclusion, our findings indicate that MCA and BA velocity measurements, as a percentage of the values during anesthesia, both give an equally accurate indication of alterations in CBF during excessive hemodynamic changes.}, address = {Department of Small Animal Medicine, School of Veterinary Medicine and Animal Sciences, Kitasato University, Aomori, Japan.}, author = {Fukushima, U. and Sasaki, S. and Okano, S. and Takase, K. and Hagio, M.}, citeulike-article-id = {334423}, citeulike-linkout-0 = {http://view.ncbi.nlm.nih.gov/pubmed/10651049}, citeulike-linkout-1 = {http://www.hubmed.org/display.cgi?uids=10651049}, issn = {0916-7250}, journal = {J Vet Med Sci}, keywords = {autoregulation, cerebral, doppler, hemodynamics, statc}, month = {December}, number = {12}, pages = {1293--1297}, posted-at = {2005-09-28 21:55:28}, priority = {0}, title = {The comparison between the cerebral blood flow directly measures and cerebral blood flow velocity in the middle and basilar cerebral arteries measured by transcranial Doppler ultrasonography.}, url = {http://view.ncbi.nlm.nih.gov/pubmed/10651049}, volume = {61}, year = {1999} }
