Technical note: An alternative use of a steerable homemade for the treatment of chronic total occlusion of an iliac artery.

INTRODUCTION: The complexity of the peripheral recanalization comes from the difficulty to cross the lesion or get into the subintimal space and its re-entry afterward, with a high risk of complications like artery dissection and/or rupture, which are life-threatening complications. To our knowledge, we report the first case of the use of a homemade steerable sheath for the successful revascularization of a heavy chronic total occlusion in a patient with unsuitable upper vascular access. TECHNIQUE: By contralateral vascular access and the use of a 6Fr 55-cm Cook Flexor sheath and a pre-looped 0.014" choice guidewire, a steerable homemade sheath was used to achieve the support, pushability, and steer needed to access the subintimal space at the origin of a heavy occluded common iliac artery, thus giving us the ability to cross the lesion. CONCLUSIONS: The homemade steerable sheath is feasible, quick, cheap, and easy to use, sparing the use of re-entry systems and catheters for the attempts of subintimal navigation. In addition, this technique gives the advantage to steer the catheters and wires as needed, avoiding non-desired re-entry points with secondary collaterals lumen compromise or extensive dissections.
