“…15 The test, and the test case DICOM, is available as supplemental material from the European Journal of Vascular and Endovascular Surgery (EJVES). 13 The case allowed the full use of all functionalities of the imaging software, including application of semi-automated centrelines and stretched view of the anatomy. 5 Individual test scores were not part of formative feedback given during the course and failing participants was not an objective of this explorative study.…”

“…A mastery learning approach is warranted and previously validated assessment tools in both EVAR sizing and procedural competence have been published. 6,7,13 Key opinion leaders from 34 countries across Europe have recently gained consensus on the curricular content for simulationbased training in vascular surgery in which EVAR and "planning and sizing" were ranked as the sixth most important skill to learn during vascular surgical training. 14 How vascular trainees can achieve sufficient skills in EVAR sizing and graft selection following a predefined curriculum and workshop format is sparsely explored although essential for successful EVAR implantation.…”

Background and aim Recognition of structured training in endovascular aortic repair (EVAR) for vascular trainees is increasing. Nevertheless, how trainees can achieve sufficient skills in EVAR sizing and graft selection is sparsely described. The aim of this study was to investigate the effect of systematic training in basic EVAR sizing and graft selection on vascular surgery trainees using a validated assessment tool. Methods Sixteen vascular surgery trainees were included in an intensive 6-h hands-on workshop in aortic sizing and stent graft selection for EVAR with a trainer-to-trainee ratio of 1:2. After 1-h lecture, participants did 5 h of supervised training on increasingly complex cases. Finally, the participants were tested using a validated assessment tool. Results All participants were able to size the test-case and select a stent graft combination in 24:35 (13:30–48:20) min (median and range). The participants’ overall test scores (lower is better) were in median 17.9 (11.9–28.4). This did not differ from the scores of experienced EVAR operators 14.7 (11.7–25.2) (<200 EVAR’s) ( p = .32) but was inferior to the score of EVAR experts 11.2 (9.8 –18.7) (≥200 EVAR’s) ( p = .01). The sub-score for anatomical measurements was 10.6 (3.9–18.8) and comparable with the experienced group 9.7 (8.1–12.8) ( p = .83) but inferior to the expert operators 6.5 (5.2–10.2) ( p = .04). The sub-score for stent graft selection was 7.5 (4.9–14.1) and comparable with experienced operators scoring 4.5 (3.6–12.3) ( p = .09) but inferior to the expert operators score of 5.0 (3.6–8.4) ( p = .01). Conclusion This study presents the results of a standardised one-day basic EVAR sizing and graft selection workshop. Vascular surgery trainees with no prior EVAR experience learned to size and select stent grafts for a simple infra-renal AAA on par with experienced EVAR operators.

“…9 The case had previously been used in a recent publication of EVAR sizing and stent graft selection and was in accordance with the company's instructions for use (IFU). 10,11 The anonymised CTA data set was segmented using OsirixLite (Pixmeo SARL, Switzerland). A reconstruction of the vasculature was imported into the CASE-IT software package (Mentice, Gothenburg, Sweden) and aligned to the bony landmarks.…”

“…12 The relevant vessel measurements had previously been estimated by six experienced EVAR operators. 10 The participants had access to the mean values of these estimates and the stent graft devices were chosen from the Bolton Treovance line at their own discretion. The participants were allowed to change any sub-parts during the procedure upon request.…”
