The objective of this study was to evaluate the safety and efficacy of peripheral intravascular lithotripsy (IVL) during endovascular treatment of iliac arterial peripheral artery disease (PAD).Abstract: METHODS: The Disrupt PAD III Observational Study is a prospective, non-randomized, multi-center single-arm study to assess the 'real-world' safety and effectiveness of the Shockwave Peripheral IVL System for the treatment of de novo calcified lesions in the peripheral arteries, with a goal of treating 1500 patients. This is an analysis of consecutive patients enrolled for treatment of an iliac artery, a specified sub-group, with at least moderate calcification and a minimum length of 20 mm.Abstract: RESULTS: Between December 2017 and July 2019, 118 patients with a total of 200 lesions were enrolled across 20 sites. 101 patients were treated primarily for claudication or critical limb ischemia, while 17 patients were treated to optimize the iliac vasculature for large-bore access. All 118 patients had successful IVL catheter delivery. The average reference vessel diameter was 7.3 mm +/- 1.9 mm, with an average diameter stenosis of 83.1% +/- 13.4% and an average lesion length of 58.3 mm +/- 57.6 mm. Severe calcification was present in 82.0% of overall cases. Stent placement was performed in 72.9% of the overall cases. As expected, the access group received less adjunctive therapies including stents (41.2%, p < 0.001). Angiographic complications were minimal with no flow-limiting dissections and a final mean residual stenosis of 12.0% +/- 12.1% with no differences between the groups.Abstract: CONCLUSIONS: Acute results with IVL in calcified iliac lesions suggest that it is a safe and effective option for calcified, stenotic iliac disease. IVL can be used successfully both for treatment of PAD symptoms and to optimize access for large-bore procedures. Copyright (c) 2020. Published by Elsevier Inc.
