Does deep femoral artery revascularization as an isolated procedure play a role in chronic critical limb ischemia?
PURPOSE: To prospectively evaluate the midterm outcome after balloon angioplasty or surgical profundaplasty of the deep femoral artery (DFA) as an isolated procedure in chronic critical limb ischemia (CLI). METHODS: Between 1995 and 2001, 21 limbs in 20 patients (mean age 77+/-8 years) were treated by revascularization of the deep femoral artery (DFA) as an isolated procedure for limb salvage. All patients had long-segment femoropopliteal occlusions unsuitable for revascularization and critical obstruction of the DFA. Clinical outcome was assessed at 1, 3, 6, and 12 months. Clinical treatment efficacy was defined as resolved CLI in surviving patients without major amputation after isolated DFA revascularization. Repeat target limb revascularization, major amputation, and death were solitary study endpoints; survival analyses were performed using the Kaplan-Meyer method. RESULTS: Angioplasty with or without stenting was performed in 14 (67%) limbs and surgical profundaplasty in 7 (33%)
