“…Among 29 confirmed cases of interruption identified in adults reported in the past 10 years,[ 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 ] there were 21 males and 8 females, with ages ranging from 18 to 62 years, with a mean of 37.7 years. The interruption at the isthmus is more common in adults, being found in three-quarters of instances, in comparison to interruption beyond the origin of the left common carotid artery, or “Type B,” in children.…”

“…An unusual finding in our patient was an atherosclerotic aneurysm in the segment of the arch proximal to the interruption, which could be explained as a consequence of hypertension. Aneurysmal disease has been reported in six other patients with interruption, affecting the ascending aorta, related in all probability to bicuspid aortopathy,[ 6 ] the arch segments distal to the interruption,[ 11 16 17 ] the collateral arteries,[ 20 ] and the LSA.

Congenital aortic anomalies are uncommon causes of secondary hypertension and are seldom suspected in the adult age group. We present a case of aortic interruption unexpectedly diagnosed on autopsy in a 38-year-old male who presented with cardiovascular collapse. Apart from interruption, a finding unique to our case was aneurysmal dilation of the proximal descending aorta just before the obstruction with thrombosis. We also attempt to review the literature for interrupted aortic arch in adults and clarify the nomenclature of interruption versus coarctation.
