Abstract

The normal aorta has three branches from its arch, but variations in this pattern are not uncommon. Our interest was to correlate the documented statistics to the variants observed in our patients. This was done by randomly selecting 60 patients on whom arch aortograms were performed. Our patients did not demonstrate all of the variants described. There was close correlation between the documented values and our patients except for the aberrant right subclavian artery which was more than three times more common in our patients.
