Arteria Subclavia ve Ana Dallarının Çok Kesitli Bilgisayarlı Tomografi (ÇKBT) ile Morfolojik ve Morfometrik Analizi

Öz

Amaç: Bu çalışmada çok kesitli bilgisayarlı tomografi aracılığı ile arteria subclavia’nın (AS) ve dallarının morfolojik ve morfometrik analizinin ortaya konması amaçlanmıştır Gereç ve Yöntem: Çalışmada, 100 hastaya ait bilgisayarlı tomografi anjiografi görüntüleri (100 sağ, 100 sol) incelenmiştir. Varyasyonel vakalar tespit edilmiş, AS’nin ve dallarının orijin noktasındaki çapları ve AS’nin iki tarafta başlangıç noktasında oluşan açılanmaları ölçülmüştür. Bulgular: AS’nin dalları için 13 farklı varyasyon nonlineer tarzda (A0, A1, A6, B0, B1, B2, B3, B4, B5, B7, C0, C1, C7 tipleri) tiplendirilmiştir (A0:%54, B0:%33, diğer tiplerin toplamı: %13). Varyasyon tiplerinin cinsiyete ve taraflara göre karşılaştırılmasında, kısmen birleştirilmiş varyasyon grupları arasında istatistiki olarak anlamlı fark bulunmamıştır. AS ve dallarının morfometrik verileri (ayrılma açısı ve başlangıç çap ölçümleri) cinsiyete ve tarafa göre karşılaştırıldığında, her iki cinsiyette başlangıç noktasında, AS sinistra çapının (kadın: 11,87±2,20 mm, erkek: 12,41±1,94 mm), AS dextra çapından (kadın: 9,10±2,31 mm, erkek: 9,78±1,84 mm) istatistiki olarak anlamlı derecede yüksek olduğu tespit edilmiştir. Aynı şekilde, her iki cinsiyette AS sinistra açısı (kadın: 92,75±36,26, erkek: 84,77±24,24), AS dextra açısından (kadın: 42,70±14,44, erkek: 40,10±16,73) istatistiki olarak anlamlı derecede yüksek çıkmıştır. Sonuç: AS’nin kanlandırdığı bölgelerin geniş ve önemli olması ve kritik bir noktada arteriyel bir kavşak görevinde bulunması, AS ve dalları ile ilgili morfometrik ve varyasyonel verilere klinik tıp sahasında ihtiyaç doğurmaktadır. AS’nin morfometrik analizi ile ilgili bilgilerin bu alanda çalışan klinisyenler için faydalı olacağını ümit ediyoruz.

Morphologic and Morphometric Analysis of the Subclavian Artery and the Main Branches of the Subclavian Artery by Multidetector Computerized Tomography (MDCT)

Öz

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.
