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

Abstract

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.
