Isolated interrupted aortic arch in an adult: A case report

Interrupted Aortic Arch Complicated with Type A Aortic Dissection in a Young Adult

Interrupted aortic arch (IAA) is a congenital anomaly characterized by a discontinuity between the ascending and descending aorta. We present a 27-year-old male patient who had presented with Stanford Type A aortic dissection and was subsequently found to have IAA on computed tomography aortogram. The patient subsequently underwent emergency surgery for the repair of aortic dissection. Although few studies with IAA and coexistent Stanford type-B aortic dissection have been described, there is no reported case in literature on IAA with Stanford Type A aortic dissection.

Type B Interrupted Aortic Arch With a Very Large Right Subclavian Artery Aneurysm in an Adult

Interruption of the aortic arch and right subclavian artery aneurysm is a rare congenital malformation. Survival in adults depends on the formation of collaterals to supply the descending aorta. The interruption of the aortic arch must be taken into account, particularly in patients with hypertension and weak pulses in the lower extremities. We present a case of aortic arch interruption and a right subclavian artery aneurysm in a woman who survived to adulthood.
