Retrograde aortic dissection following fenestrated and branched endovascular aortic repair for an extent III thoracoabdominal aneurysm

Abstract

Retrograde aortic dissection is a rare but potentially catastrophic complication after endovascular aortic repair. Reports in the literature regarding retrograde dissection after fenestrated and branched endovascular abdominal aortic repair are rare, and the incidence, risk factors, and treatment options for this complication have not yet been clearly established. Additionally, retrograde dissection after previous intervention can pose technical challenges and increases the risk of spinal cord ischemia during subsequent repair. We present a patient with an acute retrograde dissection after a fenestrated and branched endovascular aortic repair for an extent III thoracoabdominal aortic aneurysm successfully managed with proximal endovascular extension.
