<u>P</u>hoto<u>a</u>blation Using the<u>T</u>urbo-Booster and<u>E</u>xcimer Laser for I<u>n</u>-Stent Restenosis<u>T</u>reatment: Twelve-Month Results From the PATENT Study

Abstract

The PATENT study has established excimer laser atherectomy as safe for the treatment of femoropopliteal ISR, achieving high procedure success. Recurrence of restenosis indicates that removing hyperproliferative tissue alone does not solve the problem of ISR. New concepts, such as the combination of ELA with drug-eluting balloons, may prove beneficial.
