In the past decade, aneurysms have been recognized as a relatively common occurrence in reptiles.1 In bearded dragons presented to veterinary care, aneurysms are the second most common cardiovascular abnormality.2 Aneurysms are a significant cause for morbidity; bearded dragons with aneurysms are more likely to die to due cardiovascular disease compared to dragons affected by other cardiovascular diagnoses.2 During this masterclass, we will review common and less common aneurysm locations, various techniques to diagnose and characterize in details these anomalies,3 and the different treatment approaches that are currently available.3,4 References 1.
