Complications of aortic endografting

Endovascular repair of abdominal aortic aneurysm has been shown to have a significantly lower perioperative mortality rate compared with open repair. It has been a blessing for patients at high risk who were previously denied treatment for their aortic aneurysms. It does, however, have a substantial need for re-intervention for complications. Many of these complications including endoleak, endotension, migration, post implant syndrome and conversion to open repair are unique to endovascular aneurysm repair. Others including injury to the iliac arteries, graft limb thromboses and structural failure of prostheses occur with greater frequency in endovascular repair compared with open repair. It is important, therefore, for vascular surgeons to be aware of these complications including their prevention and appropriate that patients are informed of their incidence. This review discusses the local and vascular complications of endovascular repair of abdominal aortic aneurysm with an emphasis on newer aspects.
