Operators indicated the main obstacles to adopting or expanding IVUS for endovascular revascularization were cost or lack of reimbursement (69.5%), concerns about longer procedural time (47.6%), and the absence of randomized data supporting its benefit (39.0%). Overall, 80.0% of operators agreed that a large, multicenter, randomized trial was required, and 77.1% were willing to randomize patients in such a trial.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this multidisciplinary survey, the identified barriers for IVUS use in CLTI revascularization were cost\/non\u2010reimbursement, increased procedural time, and lack of randomized evidence.
