[Morphological differences in carotid angiograms and their relation to age]

Area of Science:

• Vascular anatomy
• Medical imaging
• Gerontology

Background:

• The anatomical position of the carotid bifurcation and the prevalence of internal carotid artery kinking are crucial factors in cerebrovascular health.
• Understanding age-related changes in carotid artery dimensions is essential for assessing vascular risk.

Purpose of the Study:

• To investigate the cervical level of carotid bifurcation in a Hungarian population.
• To determine the frequency of internal carotid artery kinking.
• To analyze the correlation between carotid artery diameter and age.

Main Methods:

• Conventional carotid angiograms were analyzed in 490 Hungarian patients (age 12-77).
• Carotid bifurcation level was identified relative to cervical vertebrae.
• Diameters of common, internal, and external carotid arteries were measured.
• Internal carotid artery kinking was assessed.

Main Results:

• The most common carotid bifurcation level was at the C4 vertebra, with a higher position observed in older individuals.
• A significant positive correlation was found between common carotid artery diameter and age (p < 0.05).
• Internal and external carotid artery diameters did not show a significant correlation with age.
• Internal carotid artery kinking was more frequent in individuals with a higher carotid bifurcation level.

Conclusions:

• The study establishes reference points for carotid bifurcation levels and diameters in a Hungarian cohort.
• Age influences common carotid artery diameter and bifurcation height, potentially impacting cerebrovascular events.
• Higher carotid bifurcation levels are associated with increased frequency of internal carotid artery kinking.
