title: In vivo construction of a multilayer bare-metal stent for the treatment of an aortic mycotic pseudoaneurysm.
abstract: Although not currently available in the United States, multilayer stents have been used successfully to treat a variety of aneurysms. These stents promote laminar flow and depressurize the aneurysmal portion of the vessel, while preserving side branch vessel flow. A conceivable benefit of the multilayer stent is in the treatment of infected pseudoaneurysms, given the absence of a fabric covering, a potential nidus for colonization. Here we present the case of a 64-year-old woman with symptomatic, enlarging infrarenal mycotic pseudoaneurysms who was successfully treated with an in vivo multilayer stent created by the layering of three concentric bare-metal Wallstents (Boston Scientific, Natick, Mass).
