- Azygos arch valves
An azygos arch valve refers to a venous valve at the site of the arch of the azygos vein. They are considered common and are more frequently seen at CT when high contrast material injection rates and right arm injections are used 2. They can be of various sizes and shapes, and many of them show features of insufficiency.
