Introduction
Burckhard Friedrich Kommerell, in 1936, gave the first clinical description of Kommerell diverticulum (KD) and aberrant right subclavian artery (ARSA).1 Embryologically, abnormal regression of the fourth right arch gives rise to the aberrant right subclavian artery. KD is believed to be a remnant of the primitive right dorsal aortic root. Prevalence of ARSA in the general population is around 0.5%-2.0%.
We report an emergent hybrid repair of ruptured kommerell’s diverticulum with associated contained intramural hematoma (IMH) of the aortic arch (AoA), ascending aorta (AAo), and descending thoracic aorta (DTA) in the setting of the aortic arch and ascending aortic aneurysm.
