Remote SFA Endarterectomy How I Do It David Rosenthal, MD
SFA (> 20 cm) PTA Stent LA Atherectomy

PURPOSE Retrospective, multicenter study was to examine the medium-term results of remote superficial femoral artery endarterectomy (RSFAE) and distal aSpire stenting.
STUDY GROUP (n=235) Indications for procedure: Claudication in 188 Limb Salvage in 47 All patients underwent serial duplex color-flow ultrasound scanning during follow-up. RISK FACTORS Percent (%)
RESULTS One death Wound complications in 2% Mean length of endarterectomized SFA=28.2cm Mean hospital LOS 1.3 days
RESTENOSIS (n=24) . Nine over course SFA Eight at adductor canal Seven at distal stent Intimal hyperplasia ? . = 9%
LONG SEGMENT SFA NOT SUCCESSFULLY TREATED Small caliber artery Disease long & diffuse Tortuous Low Flow Compression forces
DEBULKING SFA Increase diameter Reduce recoil & remodeling Preserving collaterals Durable procedure
CONCLUSION CONCLUSION If RSFAE and distal aSpire stenting long-term patency rates similar to AKFP, it may prove to be minimally invasive durable adjunct for treatment of SFA occlusive disease.
