Avan？os nos materiais e no tratamento endovascular de oclus？es arteriais cr？nicas totais: um relato de caso

chronic arterial occlusions with great calcium component are usually a factor of limitation to endovascular treatment to the difficulty to transpose these lesions with guidewires and catheters commonly used. we reviewed the literature and described a case of endovascular treatment of a total occlusion of external iliac artery, where the use of new materials developed specifically to the treatment of such injuries was critical to the success of the case.
