The Role of Intravascular Ultrasound in Aortoiliac Endovascular Interventions: International Expert-Based Delphi Consensus

INTRODUCTION: Intravascular ultrasound (IVUS) provides cross-sectional information on the intraluminal features of blood vessels, aiding procedural planning and postprocedural assessment of results. Although the use of IVUS in aortic procedures is increasing worldwide, consensus on best practices in aortoiliac interventions is still lacking. This study aims to obtain experts' consensus and define recommendations regarding applications of intravascular ultrasound in aortoiliac endovascular interventionsMethods:Delphi consensus methodology was performed over 3 rounds, using a panel of 27 experts. Each member was asked to grade (grade A-grade D) 26 statements regarding various applications of IVUS in aortoiliac surgery. Statements that passed the first round were proposed at the second round unmodified. Statements that failed the first round underwent stylistic modifications without altering their meaning and were proposed in the second and third rounds. Agreement and consistency were used to develop recommendations on the applications of IVUS in aortoiliac endovascular interventions. RESULTS: After 3 rounds, 17 recommendations were made (16 grade B, 1 grade A), whereas 8 statements were rejected, and the core team eliminated 1. Ten recommendations (58.8%) obtained grade IV (poor), 1 (5.9%) grade III (fair), 2 (11.8%) grade II (high), and 4 (23.5%) were classified as grade I (very high). CONCLUSIONS: Intravascular ultrasound is an important adjunct imaging technology in hybrid rooms. Most of the recommendations concerned the use of IVUS in aortic dissection. Other important recommendations for preoperative planning and evaluation of postoperative results were made in radioprotection, aortic aneurysms, and blunt thoracic aortic injury. Intravascular ultrasound assistance in aortoiliac occlusive disease is not routinely recommended at the present time.Clinical ImpactThis international expert-based Delphi consensus provides a comprehensive perspective on the current applications of intravascular ultrasound across various aspects of aortoiliac endovascular therapy. Clinical practice guidelines are currently lacking recommendations on the use of intravascular ultrasound (IVUS) as an adjunctive tool in aortoiliac endovascular surgery; therefore, this study aims to fill the current gap in the literature by assessing the role of IVUS across high-volume aortic centers and offering recommendations on possible IVUS applications in aortoiliac endovascular interventions. Areas of ongoing debate regarding IVUS are also highlighted in this article, to provide inputs for further research.
