Objective: We aimed to investigate the morphologic and morphometric analysis of the subclavian artery (SA) by using multidetector computed tomography Material and Method: In this study, Computed Tomography Angiography images of 100 patients (100 right, 100 left) were studied. Variational cases were detected, and the angle that appeared origin of SA, as well as the diameters corresponding to the origin of SA and of its branches, were measured. Results: Thirteen different variations have been described while performing classification in non-linear base (A0, A1, A6, B0, B1, B2, B3, B4, B5, B7, C0, C1, C7 types) for the ramification patterns of subclavian artery (A0:54%, B0:33%, other types total:13%). No significant differences were observed on partially united variation types between sexes and both sides. Morphometric data of the subclavian artery and its branches (separation angle and initial diameter measurement) were studied in a comparative statistical analysis based on sex and lateralization. This analysis showed statistically significant results in the comparison of the mean diameters of SA at the starting point between sides, on both sexes [left SA: (female: 11.87±2.20 mm, male: 12.41±1.94 mm), right SA (female: 9.10±2.31 mm, male: 9.78±1.84 mm) (p<0.05). Likewise, there was a statistically significant difference between the left SA angle and right SA angle measurements [left SA angle: (female: 92.75±36.26, male: 84.77±24.24), right SA angle: (female: 42.70±14.44, male: 40.10±16.73)] on both sexes. Conclusion: As the area in which the blood is being supplied by SA is wide and important, and its function is to serve as a crucial arterial intersection, morphometric data and variations regarding SA and its branches are needed in the field of medicine. We hope this study may contribute to the literature in this field of research and be helpful for clinicians interested in SA.
