Key result
Multilayer flow modulators offer minimally invasive thoracoabdominal aortic repair aiming to abolish spinal injury.
Why the study?
Thoracoabdominal aortic repair is a high-risk, complex procedure with significant morbidity and mortality, and the multilayer flow modulator (MFM) offers a minimally invasive alternative with uncertain clinical effectiveness.
The multilayer flow modulator stent represents a potentially disruptive, minimally invasive technology for high-risk thoracoabdominal aortic repair that warrants further exploration.
Multilayer flow modulators may offer an alternative in high-risk TAAA; leaves open need for prospective trials before wider adoption.
Thoracoabdominal aortic repair is a high-risk procedure in most experienced centers, not only because of anatomical complexity but also due to the fragility of the patients in whom these aneurysms occur. Such repairs are complex, time-consuming and impose a systemic injury upon the patients, regardless of whether the repair is performed by open surgery or via a fenestrated/branched technique. The substantive risks associated with such repairs include death, dialysis and paralysis. The multilayer flow modulator (MFM) is a disruptive technology which promises a minimally invasive reproducible treatment option, with clinical results demonstrating physiological modulation of the aortic sac with abolition of spinal injury. The mode of action of MFM forces us to completely rethink aneurysm pathogenesis and, consequently, it has been met with much cynicism. We aim to uncloak some of the mystery surrounding the MFM, clarify its mode of action and explore the truth behind its clinical effectiveness.

Sultan et al. (2015) conducted a review in Thoracoabdominal aortic aneurysm. Multilayer flow modulator (MFM) was evaluated. The multilayer flow modulator is a minimally invasive technology for thoracoabdominal aortic repair that aims to physiologically modulate the aortic sac and abolish spinal injury.
