Endograft Collapse after Standard Endovascular Aneurysm Repair Implantation: A Report of Two Cases.

Endovascular aneurysm repair (EVAR) has emerged as the preferred treatment for abdominal aortic aneurysm (AAA), offering advantages such as reduced mortality, faster recovery, and fewer complications compared to open repair (OR). However, concerns persist regarding long-term durability, and the need for reinterventions. Among all reported EVAR complications, endograft collapse poses a significant challenge, particularly when presenting with acute lower limb ischemia (ALI). The aim of this report is to describe two cases of non-dissection-related abdominal endograft collapse manifesting as ALI, requiring urgent intervention, emergent conversion to OR and complete endograft removal.
