Abstract
Subclavian artery aneurysm (SAA) is a rare condition seen in less than 1% of peripheral artery aneurysms. It is usually asymptomatic. However, it may become symptomatic as a result of pressure on the surrounding organs due to the progressive growth of the aneurysm. The standard treatment for SAA is surgery. In this article, we wanted to present a 63-year-old male patient who presented with the complaint of shortness of breath and was operated on with the diagnosis of Right Subclavian artery true aneurysm on thoracic CT angiography.
