JACC CARDIOVASCULAR INTERVENTIONS. Percutaneous Revascularization for Peripheral Arterial Disease. Paclitaxel Saves the Day

Ehtisham Mahmud, MD

Patients presenting with femoropopliteal (FP) disease often require revascularization for lifestyle-limiting claudication medical therapy that failed, or for critical limb ischemia. Percutaneous revascularization for FP disease has been fraught with challenges since the initial description of percutaneous transluminal balloon angioplasty (PTA) of the FP artery. Due to high rates of arterial dissection and restenosis after PTA, randomized comparisons of self-expanding stents and PTA for FP disease have been performed and have demonstrated the superiority of stenting ((1),2). Nevertheless, restenosis rates with self-expanding nitinol stents are 19% to 37% at 1-year follow-up, and options for the treatment of FP restenosis are limited ((1),2). Additionally, because this vessel undergoes significant torsion, extension, and flexion during daily activity, FP stent fractures have been reported that are associated with restenosis (3) and potential distal embolization of stent fragments. Self-expanding stent grafts covered with expanded polytetrafluoroethylene (ePTFE) (Viabahn, Gore Medical, Newark, Delaware) lead to comparable outcomes as surgical FP bypass using prosthetic conduits, (4) but can result in occlusion of collaterals and are not an appropriate initial treatment option for most patients with FP disease. Clinical outcomes from registries evaluating the use of extraction, rotational, and laser atherectomy for the treatment of FP disease have been encouraging but have not been compared in an adequately powered randomized clinical trial against PTA.

JACC CARDIOVASCULAR INTERVENTIONS. Treatment Paradigms for the Superficial Femoral Artery. Are They A-Changin?

Dierk Scheinert, MD

The main limitation of endovascular treatment modalities in the femoropopliteal tract is the high rate of recurrent lesions necessitating repeat interventions. Although 1-year patency rates of plain balloon angioplasty might be as low as 30% to 40% (1), improved results have been reported with a primary stenting approach. Nevertheless, depending on the lesion length, in-stent-restenosis rates at 1 year are still in the range of 20% to 40% (2- 5). Particularly in longer lesions, the occurrence of stent fractures seems to contribute to the development of in-stent-restenosis and has the potential to further complicate subsequent endovascular procedures (6).

ENDOVASCULAR TODAY. Extreme Options After Failed Antegrade CLI Treatments

Marco Manzi, MD, and Luis Mariano Palena, MD

Critical limb ischemia (CLI) occurs as a result of progressive obstructive atherosclerosis, most closely associated with tibial and pedal artery disease. Restoration of arterial blood flow can achieve relief of rest pain and improves wound healing, and revascularization is considered more and more the first-line treatment for CLI and foot salvage.
