Implication

CT angiography analysis demonstrates anatomical variations in carotid length and tortuosity across age and sex, highlighting key dimensions for neurointerventional catheter design.

Key Points

To quantify anatomical variations in the length, diameter, and tortuosity of the extracranial common carotid and internal carotid arteries extending from the aortic arch to the skull base.
CT angiography analysis was conducted on N=100 patients.
Vascular dimensions—including lengths, diameters, and tortuosity indices of the common carotid artery (CCA) and internal carotid artery (ICA)—were measured from the aortic arch to the skull base.
Carotid artery length from aortic arch to skull base was longer on the right than the left (22.2±2.2 cm vs 20.8±1.9 cm, p<0.0001), driven primarily by right CCA length (13.6±1.2 cm vs 12.4±1.4 cm, p<0.0001).
Both CCA and ICA were longer in men than women (CCA: 13.6±1.5 cm vs 12.3±1.6 cm, p<0.0001; ICA: 8.9±1.3 cm vs 8.2±1.3 cm, p=0.0001) and longer in patients aged ≥60 years than in those <60 years (CCA: p=0.04; ICA: p=0.0002).
Tortuosity of both CCA and ICA was higher in patients aged ≥60 years (1.2±0.2 and 1.3±0.1) compared to patients <60 years (1.1±0.1 for both, p<0.0001), with no significant differences observed in arterial diameters.
