Diamondback in Peripheral Vascular Disease

Following peripheral angiography, patients with significant SFA or below the knee artery disease (≥ 50%) or total occlusions (100%) will have a baseline OCT imaging of the target vessel and the lesion be treated with proper size CSI burr. Repeat OCT imaging will be performed after CSI. Drug eluting balloon angioplasty may be performed in discretion of the operator. If DEB is used, a final OCT imaging will be performed to assess lesion expansion and possible dissections. Balloon sizing will be based on 1:1 vessel ratio with the length covering from minimally diseased distal segment to minimally diseased proximal segment. We will try to avoid use of stents.
