Hypothesis

The study aims to clarify the role of aging in duplex indices of vertebral arteries.

Conclusion

Duplex indices of vertebral arteries are age independent in adults.

Supporting Evidence

  • In patients younger than 60 years, peak systolic velocity (PSV) and flow volume (FV) were higher in the left vertebral artery.
  • There was no significant difference in diameter, PSV, RI, and FV between the younger and older groups.
  • Mean diameter of vertebral arteries was 3.25 mm in younger adults and 3.42 mm in older adults.

Takeaway

The study found that the size and blood flow in the vertebral arteries don't change much as people get older.

Methodology

The study used color Doppler ultrasound to evaluate vertebral arteries in 96 volunteers aged 20 to 95 years, divided into two groups based on age.

Limitations

The study excluded patients with severe hemodynamic stenosis, which may limit the generalizability of the findings.

Participant Demographics

40 patients younger than 60 years (mean age 36.25 years) and 56 patients older than 60 years (mean age 69.21 years), including both males and females.
