Aneurysm morphology matters: Fusiform vs. saccular

摘要

Approved indications for commercially available thoracic stent-graft devices are delineated with clarity in the Instructions for Use (IFU) and include all forms of true aortic aneu-rysms, both fusiform and saccular, as well as penetrating aortic ulcers (PAU). These lesions were defined as the appropriate targets for endovascular treatment in the investigational protocols anchoring the various clinical trials that tested device safety and efficacy before approval could be granted by the US Food and Drug Administration and regulatory agencies around the world.
