Abstract
In patients with a femoropopliteal chronic total occlusion (CTO) after femoro-femoral (FF) bypass surgery, it is often difficult to perform endovascular therapy because of access site problems. We have treated two patients with CTO of the superficial femoral artery (SFA) using an FF crossover bypass graft. The two cases were a man with intermittent claudication and acute limb ischemia, respectively. Enhanced computed tomography showed occlusion of the left SFA and the FF bypass previously performed was patent in both cases. We punctured the right common femoral artery and a guiding sheath was inserted to the left common femoral artery. A guidewire successfully passed through the intraplaque lesion by intravascular ultrasound-guided wiring in both cases. Revascularization was successfully achieved using drug-coated balloons and using drug-eluting stents, respectively. An FF crossover bypass graft may be a good access route for complex femoropopliteal cases, such as CTO lesions.
