Aneurysm of aberrant right subclavian artery arising from diverticulum of Kommerell. Report of a case with tracheal compression

A 74-year-old woman presented with severe dyspnea without dysphagia. Computed tomographic scans and Digital subtraction angiography revealed the left aortic arch with an aberrant right subdavian artery arising from the Kommerell's diverticulum and tracheal compression. ?he aortic arch and the Kommerell's diverticulum were aneurysmal and were responsible for this compression. Surgical relief was accomplished by replacement of the aortic arch and reconstruction of the four brachiocephalic vessels with vascular prostheses through a median sternotomy incision extending into the right supraclavicular region.
