Where are we with drug eluting balloons and stents for SFA? Veronesi J. University of Modena and Reggio Emilia
PTA and BMS in SFA 12 Months Primary Patency BMS provides improved patency, but data are limited for medium and long lesions medium and long lesions
How can we keep SFA open?
DEB Drug eluting balloon Local release of medication into the vessel wall during dilatation
DEB Same Drug - Different Excipients and Coating Techs
5 DEB Trials with 6-month LLL Primary Endpoint DEB vs Standard Balloon De novo lesions, 6-months LLL in SFA
DEB vs PTA Meta-analysis 4 Fem--‐pop trials: Thunder, FemPac, Levant I, Pacifier 4 Fem--‐pop trials: Thunder, FemPac, Levant I, Pacifier 433 patients 433 patients DEB at 10.3 months --‐> reduced TLR, LLL, Restenosis DEB at 10.3 months --‐> reduced TLR, LLL, Restenosis All cause mortality unchanged All cause mortality unchanged Cassese et al. 2012
DEB - Current issues 1.Intermittent claudicatio 2.Costs 3.Calcifications 4.Atherectomy 5.Long Lesions Fanelli et al
DEB - Our indications In-stent restenosis In-stent restenosis Femoro-popliteal segment disease Femoro-popliteal segment disease Lesions < 10 cm Lesions < 10 cm No calcified lesions No calcified lesions Young patients Young patients University of Modena and Reggio Emilia

CONCLUSIONS DEB & DES in SFA DEB in SFA has demonstrated (in RCTs) clinical and morphologic benefits in the mid-term compared with uncoated balloon DEB in SFA has demonstrated (in RCTs) clinical and morphologic benefits in the mid-term compared with uncoated balloon DES promises improved patency compared with BMS DES promises improved patency compared with BMS Results from different DES trials are controversial Results from different DES trials are controversial “Drug-eluting technology” seems to reduce the need for reinterventions and compensation with costs “Drug-eluting technology” seems to reduce the need for reinterventions and compensation with costs Promising technology with long DEB and drug bioabsorbable stents is desirable Promising technology with long DEB and drug bioabsorbable stents is desirable
