Objective: Carotid anthropometry is an important asset in planning Neuroendovascular intervention, especially in cases of placement of stents, flow diverters and Stentrievers. The data on angiographic normative values of carotid circulation in the adult age group is not satisfying enough. The dimensions of ICA (Internal Carotid Artery), ECA (External Carotid Artery) and CCA (Common Carotid Artery) circulation on digital subtraction angiograms of adult patients are the goal of this study.

Material and Methods: The length of ICA, ECA, diameters of CCA in transverse and its length have been measured with CT angiogram. The study group consisted of 49 patients (mean age 49.63± 13.26). Height and weight of patients were measured and their BMI values were calculated. The distribution demonstrated by age-lateralization was imaged depending on strata and location in the carotid system.

Results: SD and mean which have been found in statistical analyses were 49.63 ±13.26 for age, 166.55 ± 6.71 for height, 71.82 ± 7.80 for weight, 26.02 ± 2.70 for BMI, 6.54 ± 0.70 for cctrg (Common Carotid Artery, transvers diameter, right), 6.58 ± 0.77 for cctl (Common Carotid Artery, transvers diameter, left), 7.96 ± 1.27 for cclr (Common Carotid Artery, length right), 8.10 ± 1.23 for ccll (Common Carotid Artery length, left), 6.64 ± 0.95 for iclr (Internal Carotid Artery, length, right), 67.2 ± 0.95 for icll (Internal Carotid Artery, length, left), 4.98 ± 0.83 for eclr (External Carotid Artery, length, right), 5.11 ± 0.88 ecll (External Carotid Artery, length, left). According to lateralization (right-left) all values were higher in left side (p<0.05).

Conclusion: In the light of these findings, by thinking three dimensional damage to internal, external and common carotid artery might be prevented.
