Farhoudi M, Kermani S, Sadeghi-Bazargani H - BMC Res Notes (2010)

Bottom Line: Peak systolic, end diastolic and mean velocities of nine main intracranial arteries were determined using TCD.Mean age among males was 40 years and among females it was 39.Mean blood flow velocity in middle, anterior and posterior cerebral arteries, vertebral and basilar arteries was 60 +/- 8, 52 +/- 9, 42 +/- 6, 39 +/- 8 and 48 +/- 8 cm/sec respectively.

ABSTRACT

Background: Transcranial Doppler (TCD) is a noninvasive, less expensive and harmless hemodynamic study of main intracranial arteries. The aim of this study was to assess normal population values of cerebral blood flow velocity and its variation over age and gender in a given population.

Findings: Eighty healthy volunteers including 40 people with an age range of 25-40 years (group1) and 40 persons with an age range of 41-55 years (group2) were studied. In each group 20 males and 20 females were enrolled. Peak systolic, end diastolic and mean velocities of nine main intracranial arteries were determined using TCD. Mean age of the studied volunteers was 31.6 +/- 4.50 years in group one and 47.2 +/- 4.3 years in group two. Mean age among males was 40 years and among females it was 39. Mean blood flow velocity in middle, anterior and posterior cerebral arteries, vertebral and basilar arteries was 60 +/- 8, 52 +/- 9, 42 +/- 6, 39 +/- 8 and 48 +/- 8 cm/sec respectively. Cerebral blood flow velocities among females were relatively higher than males. Cerebral blood flow velocity of left side was relatively higher than right side.

Conclusion: Compared to previous studies, cerebral blood flow velocity in this population was relatively higher.

Mentions: There were significant side to side differences of parameters only in both MCAs. Peak systolic blood flow velocity in different cerebral vessels are compared for three age groups in figure 1 and mean velocities of the same vessels are compared in figure 2 showing slight decrease over age in some vessels.
