Key result
Age over 60 shows no difference in vertebral artery flow volume or Doppler indices.
Why the study?
The role of aging in duplex indices of vertebral arteries and its impact on cerebral vascular demand was unclear.
Does aging affect duplex indices of vertebral arteries in adults?
Observational (n=96)
No
Does aging affect duplex indices of vertebral arteries in adults?
Duplex indices of vertebral arteries appear to be age-independent in adults, with no significant differences between those younger and older than 60 years.
Answers are grounded in this paper and cite their sources.
Aging may alter vertebral artery duplex indices; leaves open need for age-adjusted norms or outcome links.
BACKGROUND: Considering the role of aging in brain atrophy and cerebral vascular demand, we carried out this study to clarify the role of aging in duplex indices of vertebral arteries. METHODS: From June 2005 to June 2006, 96 volunteers with age range of 20 to 95 years, were evaluated with color doppler for duplex indices of vertebral arteries. Sever hemodynamic stenosis was excluded in all of these patients. These volunteers were subdivided in two groups: younger and older than 60 year old. In all of these patients we measured diameter, peak systolic velocity (PSV), resistive index (RI), and flow volume (FV) of vertebral arteries in right and left sides. RESULTS: There was no significant difference in diameter, PSV, RI and FV between two groups. We have clarified that in patients younger than 60 year old, comparing right and left vertebral arteries, PSV and FV were higher in left side. CONCLUSION: Duplex indices of vertebral arteries are age independent in adults.

Nemati et al. (2009) conducted an observational in Healthy volunteers (n=96). Age > 60 years vs. Age < 60 years was evaluated on Flow volume (FV) of vertebral arteries (p=0.76). There were no significant differences in vertebral artery diameter, peak systolic velocity, resistive index, or flow volume between adults older than 60 years and those younger than 60 years.
