Morbidity of endovascular abdominal aortic aneurysm repair is directly related to diameter

Patients with a larger AAA have comorbidities and anatomic factors associated with a more difficult repair. The higher morbidity seen with larger aneurysms represents both anatomic and patient factors but seems to have a greater impact on endovascular repairs. However, endovascular repair still results in fewer near-term complications than open repair across all size strata.
