Duplex-guided balloon angioplasty and stenting for femoropopliteal arterial occlusive disease: An alternative in patients with renal insufficiency

Duplex-guided balloon angioplasty seems to be a safe and effective technique that allows renal patients to experience continued limb salvage and relief from claudication without the risk of developing dye-induced acute renal failure. Other advantages include direct visualization of the puncture site, accurate selection of the proper size of balloon and stent, confirmation of the adequacy of the technique by hemodynamic and imaging parameters, and avoidance of radiation. Although this technique holds considerable potential, longer follow-up will help to fully evaluate its broader applicability.
