Techniques for Infrapopliteal Arterial Bifurcation Stenting

Abstract

Endovascular treatment of infrapopliteal peripheral arterial disease (PAD) is an established and effective treatment strategy for patients with symptomatic PAD. Increasingly, complex infrapopliteal lesions are treated with an endovascular first approach, especially in the setting of critical limb ischemia (CLI) for limb salvage, avoiding major amputations which impact on mobility and quality of life. However, many complex infrapopliteal lesions involving the bifurcation of the tibial arteries remain challenging to treat because of recoil or acute dissection after angioplasty and may require stenting using specialized techniques. We illustrated techniques for infrapopliteal arterial bifurcation stenting using case-based examples. The techniques covered include the single-stent, culottes, kissing, crush, and T-stenting techniques, and each is considered based on individual strengths and limitations. Infrapopliteal bifurcation stenting allows complex bifurcation lesions to be treated effectively when flow-limiting complications are encountered after angioplasty.
