SACCULAR ANEURYSM IN THE RIGHT-SIDED AORTIC-ARCH - A SUCCESSFULLY CORRECTED CASE

We report the surgical treatment of a rare case of true aortic aneurys m in a right-sided aortic arch. A 49-year-old female patient with obst ructive respiratory problems demonstrated a true aneurysm with a diame ter of 58 mm located at the right-sided aortic arch between the right carotid artery and right subclavian artery. Surgery was successfully p erformed by replacing the arch including the aneurysm with a-prostheti c graft. The positions of true aneurysms in the right-sided aortic arc h can be divided into two subtypes: first, the transverse arch between the right carotid artery and right subclavian artery, and second, the base of the subclavian artery, the Kommerell's diverticlum. The regio n is informative for consideration of the surgical approach toward ane urysms of this entity.
