Patterns in Complex Aortic Vascular Surgery Training and Early Career Practice

Abstract

Recent literature has suggested a decreasing experience with open aortic surgery among recent vascular surgery graduates. While trainees have a wide exposure to endovascular aortic repair, experience with both endovascular and open management of thoracoabdominal aneurysms, as well as the early career surgeon comfort with these procedures, remains unknown. Thus, we sought to evaluate early practice patterns in the surgical treatment of complex aortic surgery among recent U.S. vascular surgery graduates. An anonymous survey was distributed all vascular surgeons who completed vascular surgery residency or fellowship in 2020. Self-reported data assessed the number and type of cases performed in training, surgeon experience in early practice, and surgeon desire for additional training in these areas. A total of 62 surgeons completed the survey with a response rate of 35%. Seventy-nine percent of respondents completed fellowship training (as compared to integrated residency), and 87% self-described as training in an academic environment. Sixty-six percent performed fewer than 5 open thoracoabdominal aortic surgeries and 58% performed fewer than 5 four-vessel branched/fenestrated aortic repairs (F/BEVAR), including 56% who completed fewer than 5 physician modified endovascular grafts repairs. Only 11% of respondents felt adequately prepared to perform open thoracoabdominal operations following training. For both open and F/BEVAR procedures, more than 80% respondents plan to perform such procedures with a partner in their current practice, and the majority desired additional open (61%) and endovascular (59%) training for the treatment of thoracoabdominal aneurysms. The reported infrequency in open thoracoabdominal and multi-vessel branched/fenestrated aortic repair training highlights a desire and utility for an advanced aortic training paradigm for surgeons wishing to focus on this area of vascular surgery. Further research is warranted to determine the optimal way to provide such training, whether through advanced fellowships, junior faculty apprenticeship models, or regionalization of this highly complex patient care. The creation of these programs may provide pivotal opportunity, as vascular surgery and the management of complex aortic pathology continues to evolve.
