Vertebrosubclavian trunk is a very rare branch of arch of aorta

What is it about?

After our report on vertebrosubclavian trunk in a cadaver, we analysed contrast enhances CT images of thorax of 410 patients and observed the presence of the trunk in 0. 73% cases. In one patient we observed two common trunks from the arch, the bovine trunk and vertebrosubclavian trunk. Therefore careful observation and interpretation of CT images is essential for identification of atypical branches of the arch of aorta.

Why is it important?

Appreciation of atypical branching pattern of arch of aorta will be helpful in safe performance of surgical and interventional procedures and interpretation of radiological images. They may also suggest the possibility of development of thoracic aortic disease.
