Abstract

Background: In this study, our aim is to describe the sinoatrial node (SAN) artery and to define the typical course and variations of it in a Turkish population.Methods: We retrospectively examined cardiac computed tomography (CT) images of 107 cases acquired with a dual-source multidetector system. Using special software; three-dimensional, maximum intensity projection and curved multiplanar images were generated and evaluated. After depiction of the SAN arterial supply: firstly, the trace of the artery was defined; secondly, calibration at the origin measured and then percentages of different types were calculated.Results: A single SAN artery which originated from the proximal 35 mm of the right coronary artery (RCA) was detected in 97 (91%), from the proximal left circumflex artery in four (4%), directly from the RCA sinus in three (3%) and from the conal branch of the RCA in two (2%) cases. Only one (1.02%) encircling SAN artery was detected.Conclusion: The arterial blood supply to the SAN artery can be imaged easily with dual-source multidetector CT examination by processing the routine cardiac CT sections. Awareness of these features (supply to the SAN) is important before invasive procedures like surgery or catheter angiography to prevent potential damages. Compared with the literature, our findings suggest variability between different races, concerning the percentages of the different types of arterial supply to the SAN.

Özet

Amaç: Bu çalışmada, sinoatriyal nod (SAN) arteri açıklandı ve Türk toplumundaki tipik seyri ve varyasyonları tanımlandı.Çalışma planı: Çift tüplü bir multidedektör sistem ile incelemeleri gerçekleştirilmiş 107 olgunun kardiyak bilgisayarlı tomografi (BT) görüntüleri geriye dönük olarak incelendi. Özel yazılım programı kullanılarak sistemin üç boyutlu, maksimum intensite projeksiyon ve multiplanar düzlem görüntüleri oluşturuldu ve değerlendirildi. Sinoatriyal nod arteryel desteği tespit edildikten sonra, öncelikle trasesi tanımlandı; ikincil olarak ise orijine yakın kalibrasyonu ölçülerek, değişik formların oranları hesaplandı.Bulgular: Olguların 97’sinde (%91) sağ koroner arter (SağKA)’in proksimal 35 milimetrelik segmentinden kaynaklanan tek SAN arteri bulundu, tek SAN arteri dördünde (%4) proksimal sol sirkümfleks arterden, üçünde (%3) doğrudan sağKA sinüsünden ve ikisinde (%2) ise sağKA’nın konal dalından kaynaklanmakta idi. Sadece birinde kuşatılmış SAN arteri tespit edildi.Sonuç: Sinoatriyal noda sağlanan arteryel kan desteği, çift tüplü multidedektör BT sistemleri ile elde edilmiş rutin kardiyak BT kesitlerinin işlenmesi ile kolaylıkla görüntülenebilir. Bu arteryel desteğin özelliklerinin daha önceden bilinmesi, cerrahi veya kateter anjiyografi gibi invaziv işlemlerde yaralanmanın engellenmesi açısından önemlidir. Literatür ile karşılaştırıldığında, bulgularımız SAN arteryel desteğinin farklı ırklar arasındaki değişkenliği farklı tiplerinin ve yüzdelerinin bulunduğunu göstermektedir.
