One-Year Results of the Multilayer Flow Modulator Stent in the Management of Thoracoabdominal Aortic Aneurysms and Type B Dissections

MFM implantation instigates a process of aortic remodeling involving initial thrombus deposition, which slowed between 6 and 12 months. Increasing sac size did not herald rupture, and the MFM was not associated with loss of native side branches. With physiological modulation of the aneurysm, the MFM offers promise for resolution of complex thoracoabdominal pathology with off-the-shelf availability, but this disruptive technology requires further development and technical refinement. Long-term follow-up of the registry patients is mandatory before establishing a randomized controlled study.
