Practice Patterns and Barriers to Vascular Genetic Testing Among Vascular Surgeons

Engaging patients living with or at risk of aortic dissection via the Aortic Dissection Collaborative, physician education in vascular genetics was identified as a research priority. We surveyed vascular surgeons to characterize practice patterns, motivations, and barriers regarding aortopathy genetic testing. An anonymous 27-question survey was distributed on social media platforms between November and December 2022. Domains included demographics, vascular genetic education, testing attitudes and utilization, and experience in treating patients with genetic vascular aortopathies. The analysis included summary statistics and unpaired t-test to compare responses by interest in incorporating testing and practice type. A total of 171 vascular surgeons from 15 countries responded to the survey (23% trainees). Over half received vascular genetics education during training (59%), and most (86%) were interested in incorporating genetic testing into their practice. Academic surgeons were more likely to have cared for a patient with a known genetic aortopathy over the past year than surgeons in hospital-based and private practices (83% vs. 56% vs. 27%; P
