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.
