Abstract
Treatment of chronic total occlusions of the iliac and femoral-popliteal vessels with endovascular techniques has become the standard approach for shorter lesions and is increasingly applied to long, complex arterial occlusive lesions. As the complexity of the arterial occlusions increases, the demands for technical skills and devices needed to successfully cross and treat the occlusion also increases. We describe here our technique for treatment of iliac and femoral-popliteal occlusions. Important aspects of that that have allowed for a high technical success include (1) the use of hydrophilic wires and catheters to traverse occlusions in the subintimal plane, (2) femoral access with axially supported catheters or sheaths to apply the force needed for successful recanalization, and (3) the use of true lumen reentry devices when, after crossing the occlusion, the wire or catheter cannot be manipulated into the true lumen beyond the occlusion.
