Amaç: Bu çalışmada çok kesitli bilgisayarlı tomografi (ÇKBT) ile torakal aortik varyasyonları ve görülme sıklığını değerlendirmeyi amaçladık.
Gereç ve yöntem: Hastanemiz Radyoloji Ünitesinde Ocak 2016-Mart 2019 tarihleri arasında çekilen 2978 kontrastlı toraks bilgisayarlı tomografi tetkiki torakal aortik varyasyon varlığı, varyasyonların cinsiyet farklılığı yönünden retrospektif olarak değerlendirildi.
Bulgular: Çalışmamızda torakal aortik varyasyonu görülme oranı %22.5 olup bu oran kadınlarda %25.76, erkeklerde %20.63 idi. En sık görülen torakal aortik varyasyon trunkus brakiosefalikus ile sol ana karotis arter aortadan ortak kökten orjin almasıdır (Bovine arkı). Görülme oranı % 13.76 idi. Diğer görülen varyasyonlar izole sol vertebral arterin aortadan çıkması, arkus aorta aberran sağ subklavyen arter (ARSA) varyasyonu, sağ arkus aorta ve aort koarktasyonudur. Bu varyasyonlara eşlik eden ikincil varyasyon ise sol vertebral aortanın arkus aortada orjin almasıdır. Kadın-erkek oranı açısından bakıldığında bovine arkı ve sağ arkus aorta varyasyonunda istatiksel olarak anlamlı fark izlenmiş olup diğer varyasyonlarda anlamlı fark izlenmedi.
Sonuç: Torakal aortik varyasyonlar çoğunlukla asemptomatik olup bazı tipleri semptomatiktir. Bu varyasyonların görüntüleme özelliklerine aşina olmak, doğru tanı ve sınıflandırma ve cerrahi tedaviye rehberlik etme açısından önemlidir. Kontrastlı ÇKBT noninvaziv bir görüntüleme yöntemi olup, bu varyasyonların kapsamlı bir değerlendirmesini sağlamaktadır.

Objective: In this study, we aimed to evaluate the thoracic aorta variations and their incidence with multidedector computed tomography (MDCT).

Materials and methods: Two thousand nine hundred seventy-eight contrast-enhanced thorax computed tomography examinations taken in the Radiology Unit of our hospital between January 2016 and March 2019 were retrospectively evaluated in terms of the presence of thoracic aortic variation and gender differences of the variations.
Results: In our study, the incidence of thoracic aortic variation was 22.5%, this rate was 25.76% in women and 20.63% in men. The most common thoracic aorta variation was originating from the common root of the truncus brachiocephalicus and left common carotid artery aorta (Bovine arc). The incidence rate was 13.76%. Other observed variations were the origin of the isolated left vertebral artery from the aorta, aberrant right subclavian artery (ARSA) variation in the aortic arch, right aortic arch and aortic coarctation. The secondary variation accompanying these variations was the origin of the left vertebral aorta in the aortic arch. In terms of female-early ratio, a statistically significant difference was observed in the bovine arc and right aortic arch variation, but no significant difference was observed in other variations.
Conclusion: Thoracic aortic variations are mostly asymptomatic and some types are symptomatic. Familiarity with the imaging features of these variations is important for accurate diagnosis and classification, and to guide surgical treatment. Contrast-enhanced MDCT is a non-invasive imaging method, providing a comprehensive evaluation of these variations.
