“…Aortic fenestration was described in 1990 for the first time [6] and, since then, many techniques have been proposed for this purpose. The re-entry catheter with a needle tip facilitates passage through the endothelial flap and allows direct cannulation of TL [7]. The maximal extension of the tip is 10 mm, which was enough in this case as the TL was narrowed and compressed between two flaps on both sides.…”

Background Several endovascular or surgical treatments have been proposed to treat total chronic occlusions of the iliac bifurcation. Nowadays, endovascular options are considered as a first choice because of the decreased per-operative morbi-mortality. Nevertheless, unexpected intraoperative events may occur, such as dissection or rupture of the iliac artery. We report a case of inadvertent bilateral false lumen kissing stents positioning, rescued with stents extensions guided with image fusion guidance. Case presentation A 60-year-old male patient referred to our Department because of a severe bilateral claudication, 8 months after an iliac kissing stent for common iliac arteries occlusion. A CT angiography (CTA) was performed, showing a bilateral dissection of the aorto-iliac bifurcation at the proximal part of the stents, which were placed into the false lumen whereas the distal part was into the true lumens (TL). Lower limb perfusion was maintained by inferior mesenteric and hypogastric arteries. As a CTA performed before the first endovascular intervention showed no dissection of the aortic bifurcation, the flaps were probably created during the previous interventions. An endovascular revision was planned. After a bilateral femoral access, the proximal part of the flap was pierced with a needle-based re-entry device, deployed under three-dimensional cone-beam CT image overlay with bi-planar fluoroscopy. The lumen patency was then restored with stents extensions up to the renal ostia. The final angiography showed stents patency. No complication occurred during the intervention. The patient was dismissed the day after, with good arterial femoral pulse and no further complications. An US color Doppler performed one month after the intervention showed satisfactory blood flow of both iliac and femoral arteries as well as a good flow in the lower limbs. Conclusions The integration of modern 3D image guidance and novel endovascular devices allows the management of adverse events with a minimally-invasive approach.
