Summary
A larger common carotid artery (CCA) diameter, measured via ultrasound, is linked to a higher risk of aortic aneurysm (AA). This increased CCA diameter also correlates with the size of thoracic and dissecting aortic aneurysms.
Area of Science:
- Vascular Surgery
- Cardiovascular Imaging
- Medical Diagnostics
Background:
- Arterial diameter changes are associated with atherosclerotic risk factors.
- Limited research exists on the link between common carotid artery (CCA) diameter and aortic aneurysm (AA) presence.
Purpose of the Study:
- To investigate the relationship between CCA diameter and the presence of AA.
- To explore the correlation between CCA diameter and AA size.
Main Methods:
- Carotid ultrasonography was used to measure CCA diameters in 132 AA patients and 414 controls (all >40 years old).
- AA size was assessed using CT, MRA, or surgical findings.
- Logistic regression analysis identified risk factors for AA.
Main Results:
- AA patients had significantly larger CCA diameters (right: 7.0±1.1 mm vs. 6.3±1.0 mm; left: 6.7±1.1 mm vs. 6.1±1.0 mm) compared to controls.
- CCA dilatation was a significant risk factor for AA, alongside hypertension and smoking.
- CCA diameter correlated with the size of thoracic and dissecting AA.
Conclusions:
- Increased CCA diameter may indicate the presence of AA.
- CCA diameter is a potential indicator and is related to the size of certain types of AA.
