Background: This study aimed to investigate the frequency of asymptomatic intracranial and extracranial artery stenosis in healthy volunteers in Kerman (Iran) in 2019 using Doppler ultrasound imaging.Method: This was a cross-sectional study conducted on healthy volunteers in Kerman in 2019. Following a public eliciting, 138 healthy volunteers having history of any disease and not treated with any medication underwent cerebrovascular evaluation with Doppler ultrasound. Demographic information, history of addiction, and sonographic findings were recorded in a checklist and then analyzed by SPSS 22.Results: Stenosis was found in 14.4% of volunteers. Stenosis had a meaningful statistically correlation with age and addiction. The most involved arteries were the posterior cerebral artery (PCA) and the middle cerebral artery (MCA). In patients with stenosis, a meaningful correlation was found between age (P = 0.03) and addiction (P = 0.04) with the involved artery. There was also a meaningful correlation between addiction and intracranial and extracranial artery stenosis (P = 0.04). Logistic regression analysis showed a significant relationship between female, addiction, and age with stenosis, as well as between the addiction with intracranial arteries stenosis (P <0.05).Conclusion: The majority of healthy residents of Kerman have asymptomatic cerebrovascular stenosis, and this is more important in the elderly, addicts, and women.
