OBJECTIVE: Early outcomes of open abdominal repair (OS) versus endovascular repair (EVAR) for abdominal aortic aneurysm were retrospectively analyzed, after commercialized devices for EVAR had become available in Japan. PATIENTS AND METHODS: A total of 781 consecutive patients (OS, n = 522; EVAR, n = 259) were treated at ten medical centers between January 2008 and September 2010. The OS group comprised patients with preoperative shock (SOS, n = 34) and without shock (NOS, n = 488). RESULTS: Patients in the EVAR group were 3 years older than those in the NOS group. There was greater prevalence of hostile abdomen, on dialysis, chronic obstructive pulmonary disease on inhaled drug, and cerebrovascular disease in the EVAR group than in the NOS group. Surgical mortality was 16 cases (2.0% in all patients, EVAR: 0.8%, NOS: 1.4%, SOS: 21%). Hospital stay >30 days was documented in 52 (11%) with NOS, 11 (33%) with SOS, and 8 (3%) with EVAR. Thirty late deaths included 6 aneurysm related death and 14 cardiovascular causes at a mean follow up of 1.0 year. The survival rates freedom from all cause death at one year, were 95 ± 1% in NOS and 94 ± 2% in EVAR respectively. CONCLUSION: Though significant differences in patient characteristics among three groups were noted, early results were satisfactory.
