Current training and practice of endovascular surgery: a survey

Endovascular surgery (EVS) has become of great interest to the vascular community. However, little data exist about the current status of training and utilization of EVS, thus prompting this survey. During a national vascular meeting, all participants (n = 132) filled out a 2-page questionnaire. Respondents (mean age 39 years, 87% male) were 68 vascular surgeons in practice (52%), and 64 fellows (48%), representing a significant fraction of trainees in North America. Practice location included university hospital (39%), private hospital/clinic (52%), and government hospital (8%). According to respondents, in their respective communities, most of the EVS was performed by radiologists (66%), followed by vascular surgeons (19%), cardiologists (13%), and vascular medicine physicians (2%). A majority of respondents (75%) currently perform EVS; surgeons in practice < 3 years had the highest rate (90%). Utilization rates among the nine interventions surveyed ranged from angiography (72%) and angioplasty (65%) to intravascular ultrasound (IVUS) (21%) and atherectomy (12%). Procedure totals showed that approximately 20% of fellows performed > 100 angiograms and 10% performed > 25 endovascular grafts/year, whereas nonfellows performed few of the latter. Most of the EVS (72%) was performed in the operating room with portable imaging equipment and EVS accounted for 14% of all vascular procedures. Most respondents (86%) believed that EVS would become a major component of vascular surgery and comprise 30% of their future practice. Seventy-six percent thought their training was insufficient and 85% said they would devote 3 months or less for further endovascular training. In conclusion, a vast majority of vascular trainees and surgeons are performing EVS, however, individual caseloads vary greatly. The belief that endovascular surgery will play an increasing role in vascular surgery practice is strong and interest in further training of short duration is widespread. Broader-based data collection and longitudinal studies on this issue are warranted.
