    Abstract:
    According to the 2007 TransAtlantic Inter-Society Consensus (TASC II) guidelines, surgery is the preferred treatment for extensive (TASC II type C and D) aortoiliac occlusive disease (AIOD). Recent studies, however, have shown that endovascular management can be an effective first-line treatment option for TASC II type C and D categories. While endovascular therapy is now commonly performed in patients with TASC II type D lesions, very few studies have investigated the feasibility and effectiveness of extending endovascular therapy to the most severe subcategory of TASC II D lesions, chronic infrarenal aortoiliac occlusion (CIAO). Herein, we present our technique for endovascular treatment of CIAO which relies on bidirectional subintimal aortoiliac dissection, wire snare for true lumen reentry, and combined balloon-expandable and self-expanding covered stent reconstruction of the aortic bifurcation and bilateral iliac arteries. This technique safely extends the reach of endovascular therapy to the most severe subcategory of TASC II D AIOD, CIAO. It is a viable minimally invasive alternative to aortobifemoral bypass surgery. Long-term follow-up of larger cohorts is needed to verify clinical efficacy and durability of therapy.
