Outcome Analysis From a Multicenter Registry on Unibody Stent-Graft System for the Treatment of Spontaneous Infrarenal Acute Aortic Syndrome (MURUSSIAS Registry).

The lack of specifically designed devices for infrarenal acute aortic syndrome (IAAS) disease remains an issue principally for its specific anatomic features. The MURUSSIAS registry retrospectively examined the outcomes of spontaneous IAAS treated using the unibody stent-graft system in a spontaneous national study; and reports the largest available data on this topic. The use of the unibody stent-graft system showed to fit the anatomic peculiarities of IAAS with excellent outcomes. This IAAS treatment strategy should be considered unless specifically designed endovascular solutions will be available.
