Course of ankle-brachial-index 12 months after intravascular lithotripsy in calcified peripheral lesions

Abstract Background Intravascular lithotripsy (IVL) is a relatively novel treatment option for calcified lesions in peripheral artery disease. Little known about the mid to long-term functional status of patients and target lesion revascularization rate (TLR) after IVL only procedure. Purpose To evaluate course ankle-brachial-index (ABI) assess 1 year intravascular performed on lesions. Methods Between December 2018 January 2021 was 61 limbs 51 presenting with Rutherford classes 2–5. Ankle-brachial-index documented before procedure as well day, 6 months within single center real-life registry. Further endpoint PTA or bypass surgery. The vast majority cases were done (58%) All procedures upper leg/pelvic stenosis. Results ABI measurement 12 42 (82%). Three pts missed due media sclerosis. Due loss follow-up, could not be 4/61 (7,8%) 12-month-ABI another 8/51 (15,6%). Initial baseline 0.6±0.26 increased 0.8±0.25 (p<0.0001) one day afterward. After months, 0.8±0.27 (n=49; p<0.0001) still significantly improved compared baseline. year, 0.7±0.22 improved, however different from (Figure 1). Target needed 7 (13%), 4 subsequent IVL, 3 2 Conclusions In our large registry, mainly stand-alone safe effective even mid-term follow up. TLR necessary 13%, which lower than previous published data (20,7% DISRUPT-PAD-II) [1]. but did maintain statistical significance, other like scoring balloon [2].
