Application of embolic protection device in renal angioplasty and stenting / 中华放射学杂志

ABSTRACT

Objective To assess the effectiveness and safety of embolic protection device in renal angioplasty and stenting.Methods From March 2003 through Feb 2005,renal angioplasty and stenting (RAS)were performed in 73 patients with severe renal artery stenosis,14 of them were done with use of distal embolic protection device(EPD,in 17 arteries ).Technical success included not only the stent placement but also the successful use of EPD.Results The EPD and stents were delivered and deployed successfully in all target arteries.The average percentage of renal artery stenosis before and after stent placement were 80.1%?9.0%,and 6.0%?4.2% respectively.The cholesterol particles were found in the EPD grossly in 2 and microscopically in 9 cases.Conclusion The use of embolic protection device during renal angioplasty and stenting is technically feasible and appears to be effective in preventing procedure-related embolization complications.
