Contemporary Treatment of Below-the-Knee Peripheral Arterial Disease in Patients With Chronic Limb Threatening Ischemia: Observations From the Vascular Quality Initiative

A retrospective analysis of the Vascular Quality Initiative between 2011 and 2020. Alternate-percutaneous balloon angioplasty (PTA) interventions, which included atherectomy, drug-coated balloons, bare metal stents, coronary drug-eluting to treat chronic limb-threatening ischemia (CLTI) significantly increased over study period from 18% 33%. Advanced age, increasing TransAtlantic Inter-Society Consensus classification, concomitant above-the-knee disease were associated with alternate-PTA intervention. Longer lesion length, insulin-dependent diabetes mellitus, bilateral PTA alone. The percentage interventions for CLTI due infrapopliteal artery last decade.
