We suggest the importance of teaching and learning endovascular skills as well as open surgical skills so that all treatment options will be available to patients with PAD.  ...  In addition, patients with CLI may be more likely to accept an endovascular procedure because of its less invasiveness rather than an open bypass procedure.  ...  The true lumens of brachiocephalic and right carotid arteries were occluded by the thrombosed false lumen.  ...
