Learning objectives 1. To illustrate the range of TransAtlantic Intersociety Consensus Document (TASC) D lesions that can be treated using endovascular techniques 2. To list and illustrate endovascular devices and techniques that can be particularly useful in this challenging group of patients Background Lower extremity peripheral arterial disease affects 20% of the UK population aged 55-70 of whom 5% are symptomatic. Symptoms range from claudication to critical limb ischaemia which can lead to limb loss. The TransAtlantic Intersociety Consensus Document on management of Peripheral Arterial Disease II (TASC II) recommends endovascular vs open surgical treatment based on the location and complexity of arterial lesions. TASC D aortoiliac lesions are classified as: Infra-renal aorto-iliac occlusion Diffuse disease involving the aorta and both iliac arteries requiring treatment Diffuse multiple stenoses involving the unilateral common iliac artery (CIA), external iliac artery (EIA) and common femoral artery (CFA) Unilateral occlusions of both CIA and EIA Bilateral occlusions of EIA Iliac stenoses in patients with aortic aneurysms requiring treatment and not amenable to endograft placement or other lesions requiring open aortic or iliac surgery TASC D femoropopliteal lesions are classified as: Chronic total occlusions of CFA or superficial femoral artery (SFA) (>20cm, involving the popliteal artery) Chronic total occlusion of popliteal artery and proximal trifurcation vessels Surgical management is recommended for both aorto-iliac and femoro-popliteal TASC D lesions, as these are considered particularly complex and challenging for endovascular techniques.

However, as a result of improved endovascular techniques and devices many centres manage TASC D lesions endovascularly. At our institution, both aorto-iliac and femoro-popliteal TASC D lesions are frequently treated with endovascular techniques. The technique used is mainly an evolution of subintimal angioplasty augmented with devices including re-entry catheters, low profile wires and balloons, and the judicious use of self-expanding and balloon mounted stents. Findings and procedure details We reviewed 38 consecutive patients (29 femoro-popliteal and 9 aorto-iliac TASC D lesions) who underwent endovascular intervention from May 2012 to October 2013. The mean age was 72 years. All patients underwent diagnostic peripheral MR or CT angiography or Duplex ultrasound, and were discussed at our multidisciplinary meeting to ensure optimal management of their disease. Endovascular deivces and techniques used for challenging TASC D patients: 1. 2. 3. 4. 5. Re-entry devices such as Outback (Cordis), Offroad (Boston Scientific) (fig. 1-9) These devices are used to gain re-entry into the lumen of an artery following subintimal dissection accross an occlusion, when the guidewire does not re-enter spontaneously. Devices designed to cross calcified chronic total occlusions (CTOs) such as TruePath (Boston Scientific) and Frontrunner (Cordis). These devices engage CTOs and cross them to facilitate intraluminal guidewire placement beyond the occlusion. Sharp dissection using back end of a Radiofocus (Terumo) standard or stiff guidewire to engage occlusions, to push through occlusions and occasionally to re-enter the true lumen (fig. 10-12). This technique is useful in dealing with calcified, resistant lesions, and when used judiciously is very safe, with a very low risk of complications such as perforation. Retrograde tibial puncture (fig 13-18). This technique can be used if an antegrade approach is unsuccessful in crossing tibial lesions. Ultrasound or fluroscopic guided puncture of a patent segment of distal tibial vessel is performed, to allow retrograde passage of a guidewire through the lesion. The guidewire is then snared from the antegrade access, to perform angioplasty. For occlusions involving the iliacs and CFA, the iliacs are stented as low as possible (just above the acetabulum), followed by angioplasty of the CFA. If there is insufficient length of patent CFA for retrograde access, the SFA or sometimes the profunda is punctured. Page 3 of 48
6. SAFARI (subintimal arterial flossing with antegrade-retrograde intervention) - this technique involves the simultaneous passage of guidewires from the antegrade and retrograde approaches in the subintimal plane across an occlusion. When the guidewires are located adjacent to each other, one of them is exchanged for a snare, to capture the other guidewire. This allows placement of a single, continous "flossing" wire through the occlusion to facilitate angioplasty +/- stent placement.

Conclusion Published literature and our experience show that a significant proportion of patients with TASC D lesions can be treated with technical and clinical success using endovascular approaches. Technological innovations and refinement of endovascular techniques have increased the number of patients to whom this option is available. Endovascular treatment can be particularly beneficial to frail patients who would tolerate open surgery poorly. A multidisciplinary approach, appropriate patient selection, operator experience and novel devices are key to success in treatment of this challenging subset of vascular disease.
