Abstract
ObjectiveTo 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.
MethodsClinical 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.
ResultsThere 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).
ConclusionELA or PMT under the DEFP in treatment of peripheral artery disease appears to be of great significance in preventing DE.
