LDD in Treatment of Femoropopliteal ISR

Status Recruiting

Clinical Trial Summary

This study will evaluate the effectiveness and safety of local drug delivery using TAPAS balloon catheter system in the treatment of femoropopliteal in-stent restenosis. Patients with femoropopliteal in-stent restenosis will randomly receive balloon dilation or balloon dilation plus local drug delivery using balloon catheter system. Their clinical outcomes (e.g. 12-month late lumen loss or late lumen loss at secondary intervention within 12 months, 6-month and 1-year patency rate of target vessel) in 1 year after the treatment will be compared.

Clinical Trial Description

Femoropopliteal occlusive disease is a common type of peripheral arterial disease. Endovascular treatment has been the first-line treatment of femoropopliteal occlusive disease. However, the in-stent re-stenosis has been a major limitation of well long-term patency after stent implantation. The chronic inflammation induced by stenting could be a main reason of restenosis. Then the concept "leave nothing behind" is proposed, and some novel treatment methods and devices are developed. Here, the investigators propose the hypothesis that using local drug delivery with TAPAS balloon system can relieve the inflammation induced by the stent implantation and balloon dilation. Therefore, 40 patients of femoropopliteal in-stent restenosis will be randomly allocated into the group "balloon dilation+local drug delivery with balloon system" or "balloon dilation only". The 1-year patency rate,12-month late lumen loss, incidence of complications, imaging parameters will be compared between two groups. ;
