Endovascular Management of Proximal Fixation Loss Using Parallel Stent Grafting Techniques to Preserve Visceral Flow

Although technically challenging, endovascular salvage of proximal fixation failure after EVAR is possible with extension to the paravisceral aorta using parallel graft techniques. Parallel chimney stent treatment for proximal fixation failure following EVAR can be performed with high technical success, low need for reintervention, and excellent midterm patency rates. Given these findings, chimney stent treatment should be considered the primary mode of therapy for those patients with limited life span and extensive medical comorbidities.
