Endovascular therapy (EVT) utilizing percutaneous transluminal angioplasty has become a standard technique to re-establish sufficient blood flow in ischemic limbs of patients with peripheral arterial disease (PAD). Long chronic total occlusion (CTO) of the superficial femoral artery (SFA) remains one of the challenging lesions in the field of EVT for PAD patients, despite the recent introduction of many dedicated interventional devices such as high-performance guidewires. In this article, we report a novel interventional technique, trans-collateral angioplasty (TCA), to improve the initial success rate of EVT for long SFA-CTO lesions. We present one representative case, and describe the technical tips and appropriate device selection criteria for the TCA procedure. The outcomes of TCA for long SFA-CTO performed last year at our institution are also summarized and discussed.
