Abstract

The arch of.the aorta gives three main branches; m lic artery, left common carotid artery and left subelavian artery. Rarely this number raise up to four or five. ClinicalIy, these variations do nol effect the dynamic eguilibrum of circulation, However, they dah cause symptoms as a result of compression on trachea Or 08sophagus. For this reason, knowledgs of the anâtomy and variations of arcus'dörtae is important for radiological GRİŞ a Sare interventions. 3 In this study, we investigate the variations of arcus aortae and its braches, Dissections on 75 preparations revealed that 65 of them are in typical form. In 8 preparations (X 10.6) we observe that brachiocephalic artery raises as one trunk with arteria carotis communiş. In 2 preparations (46 2.6) we found an Aberrant subelavian artery.

Arcus Aortae Dallarının Varyasyonları

Abstract

Arcus âortae' den, ir. brachiocephalicus, a.G.c. sinistra” ve a, subdlavia sinistra olmak üzere üç ana dal çıkmaktadır. Bu sayı nadir olirak dört veya beş'e kadar yükselebilmektedir. Klinik olarak bu vâryasyonlar, sirkülasyonun dinamik dengesini etkilememektedir. Ancak trakea'dâ, özetagüs' da bası neticesi, klinik olarak semptomlar ortaya çıkabilmektedir. Ârcu$ aortae ve dallarının varyasyonlarının bilinmesi; radyolojik tetkiklerin değerlendirilebilmesi ve cerrahi tedavilerin uygulanabilmesi bakımından da önemli bir konudur, “Toplam 75 preparatta yapılan diseksiyon sonunda tipik arcus aortae 65 preparatta (7686.6), tr. brachiocephalicus'un a.c.c. sinistra ile birlikte bir kütük olarak çıkması 8 preparatta (7 10.6) ve Aberrant a. subelavia 2 preparata (7 2.6) tesbit edilmiştir.
