title: Candidates and major determinants for endovascular repair of abdominal aortic aneurysms in Korean patients.
abstract: The purpose of this study was to determine what proportion of patients with an abdominal aortic aneurysm (AAA) would be eligible for endovascular aneurysm repair (EVAR) and to examine the major determinants for suitability of EVAR with the currently available indications. We retrospectively reviewed 3-D reconstructed computed tomography angiography of 88 patients with an atherosclerotic AAA who underwent open repair or EVAR between October 2003 and October 2010 at the Cardiovascular Center, Seoul National University Bundang Hospital. Of the 88 patients, 71 (80.7%) were treated with open repair and 17 (19.3%) were treated with EVAR. The rate of minor complications, postprocedural intensive care unit stay, and total hospital stay were significantly lower in the EVAR group. When the suitability of EVAR was reevaluated using morphologic criteria, a total of 33 (37.5%) patients were considered eligible for EVAR. Multivariate analysis revealed that proximal neck length, proximal neck angle, and aneurismal sac size were independent determinants for suitability of EVAR. Taking into account the increased clinical experience and the availability of new devices, EVAR would be applicable in about 40% of atherosclerotic AAA cases in this series of Korean patients. Accurate identification of candidates for EVAR by detailed preoperative evaluation, especially for morphologic characteristics, is essential.
