ORPHA:99079Morphological anomaly
What it is
A rare, congenital anomaly of the great arteries characterized by cranially situated aortic arch ascending into the neck above the clavicles. Most patients remain asymptomatic, some present with a murmur and a pulsatile neck mass, stridor, dyspnea, recurrent bronchitis, dysphagia or signs and symptoms of a stenosis/aneurism of the aortic arch. Other congenital heart anomalies are frequently associated, including abnormalities of arch laterality and branching, aortic coarctation or aneurysm.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
