Male and Female
Patients who had treatment for abdominal aortic and/or iliac artery aneurysm with the following criteria: maximum external diameter more than 5cm or 4-5cm with rapid enlargement, or saccular morphology which carried high risk of rupture. In some patients, they were treated for main location of common iliac artery aneurysm if their maximum size was more than twice the normal diameter.
Patients who require concomittant repair of thoracic and/or thoracoabdominal aneurysm repair or who require reconstruction of abdominal branches.

Partially published
Though significant differences in patient characteristics between EVAR and open surgical group were noted, early results were satisfactory in both groups.
Proportion of EVAR in AAA repair increased from 0% into 48.8% over 8 years. Surgical death was comaprable after patient charaqcteristics were adjusted.Overall, indication of AAA repair was extended without increasing the hospital mortality.
Late sac enlargement of AAA after EVAR was assessed, which disclosed that about 20% of cases showed sac enlargement at 5 years.
Late intervention was also assessed, which disclosed that late intervention was required in about 15% of patients after EVAR at 5 years. It include about 6% of surgical conversion such as graft replacement, sacotomy, femoro-femoral bypass or thrombectomy for graft occlusion.

The primary outcome measure was surgical mortality. It is defined as either any cause of death within 30days after operation or in-hospital mortality without discharge at any time. The secondary outcome measures included early morbidities, and intermediate term results. Details of treatments were described such as procedure time, volume of blood transfusion, and process of recovery including hours of respiratory management, length of intensive care unit stay (ICU stay), procedure failure requiring additional procedure during same hospitalization, and re-admission within 30days.
