Abstract
Objective: Outcomes of open surgery (OS) and endovascular repair (EVAR) for abdominal aortic aneurysm were analyzed, after commercialized devices for EVAR has introduced. Patient and method: A total of 383 patients (OS: 244, EVAR: 139) were treated at Tenri hospital from January 2008 to April 2012. Results: Variation of yearly patient number was not seen among 4 years from 2008 to 2011. Patient number decreased in the OS and increased in the EVAR from 2008 to 2009, but no change has in both groups from 2010 to 2011. ASA classification was no significant change in both groups. Average of risk factors was 2.0±1.0 in OS group and 2.2±1.0 in EVAR group. Extra-indication factors in instruction for use (IFU) were no significant change between two groups. In hospital morbidity and mortality were 15% and 3% in OS group, and 13% and 0% in EVAR group. Conclusion: EVAR is useful in 1st choice treatment for abdominal aortic aneurysm. However, open repair has important role for unsuitable case in IFU and emergent case.
