INTRODUCTION: The aim of this review is to explore the safety and effectiveness of intravascular ultrasound (IVUS) during lower limb endovascular interventions in patients with peripheral arterial disease (PAD).
EVIDENCE ACQUISITION: A systematic review of the PubMed and Scopus databases was performed according to PRISMA guidelines. Clinical studies evaluating IVUS as an adjunct to angiography during revascularization procedures in patients with PAD were included.
EVIDENCE SYNTHESIS: Thirteen studies were identified, with a total number of 2258 patients having had IVUS for PAD intervention. Seven investigated the role of IVUS for angioplasty and stenting, with the majority being retrospective cohorts. Technical success and patency rates ranged from 90-100% and 45-100%, respectively, with a follow-up that ranged from 4.3-63 months. Three of these studies compared IVUS and non-IVUS guided angioplasty and demonstrated a significant difference in the events of amputations or re-interventions in favor of the IVUS group. Furthermore, five studies evaluated IVUS use in true-lumen re-entry, with the technical success ranging between 97-100%. In one study, where IVUS was used for atherectomy, the technical success was 100% and the long-term patency was 90% during a 12-month follow-up. Overall, no significant peri/postoperative IVUS related complications were reported, whereas, 2 studies suggested an IVUS-associated increase in procedure costs that ranged from $1080-$1333.
CONCLUSIONS: There is limited and heterogeneous evidence regarding the use of IVUS for the management of PAD. Further research is required to elucidate the optimal role of IVUS in PAD as well as the cost effectiveness of this approach for routine use in the management of PAD.
