Endovascular Treatment of Spontaneous and Isolated Infrarenal Acute Aortic Syndrome with Unibody Aortic Stent-Grafts.

The endovascular treatment of IAAS with unibody stent-graft (AFX endovascular AAA system; Endologix Inc.) is safe and effective with promising mid-term outcomes. The use of unibody stent-grafts expands the endovascular indication, despite the usual anatomic IAAS features. Larger studies with longer follow-up are required to validate the outcomes of the reported technique.
