Conclusions
This study investigated the reported prevalence of arch anomalies and
its variants in the adult general population (50 to 85 years of age)
undergoing CT chest imaging at a tertiary care center. Arch anomalies
were under-reported and the high association with TAA in this
subpopulation (OR 2.85) may warrant more methodological approach in
reviewing the arch pattern and also more periodic imaging surveillance
and patient counselling in patients with aortic arch anomalies.
