Abstract:
Objective:To discuss the strategies of distal embolic filter protection(DEFP) during excimer laser ablation (ELA) or percutaneous mechanical thrombectomy (PMT) in treatment of peripheral artery disease.Methods:Clinical data of 29 patients undergoing ELA or PMT under the DEFP from Oct 2019 to Aug 2021 were retrospectively collected to analyze the strategies of DEFP and high-risk factors of capturing clinically significant macrodebris.Results:There were 21 males and 8 females, aged (70.3±11.0) years with 32 lesions (29 limbs) including 5 in-stent restenosis (ISR), 10 thrombosis and 17 chronic total occlusion (CTO). The technical success rate of DEFP device release and recovery was 100%. The overall debris capture rate was 77.3% and the macrodebris capture rate was 36.4%. Even with DEFP the distal embolization (DE) incidence was 3.4%. When ELA for CTO with severe calcification or long-segment ISR lesions, the capture rate of macrodebris was as high as 60.0%, and the former was significantly higher than ELA for CTO without high calcification lesions ( P<0.05). Conclusion:ELA or PMT under the DEFP in treatment of peripheral artery disease appears to be of great significance in preventing DE.
