Thoracoabdominal aortic aneurysm surgery: a different perspective on stent grafts failure

Endovascular repair of the descending and thoracoabdominal aortic aneurysm (TAAA), which is generally considered to be associated with lower morbidity and mortality than conventional open repair, appeals to both patients and clinicians. However, commonly this concept has been under continual evaluation and issues with long-term durability, disease progression and repair failure, including endoleak with all its types and not to forget aneurysm expansion, catastrophe of aortic rupture, and stent-graft infection are handing like ringing bells after every endovascular approach. In this literature review, we will review the current evidence of graft failure and delineate the actual and proposed theorems regarding the cause of failure of endovascular graft failure.
