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.
