Endovascular Aortic Aneurysm Repair for Abdominal Aortic Aneurysm: Single Center Experience in 122 Patients

Abstract

Copyrights © 2013 The Korean Society of Radiology Purpose: To analyze a single center experience of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms. Materials and Methods: Results of 122 patients who underwent EVAR were analyzed, retrospectively. Sex, age, aneurysmal morphology, hostile neck anatomy, preprocedural and postprocedural sac-diameter, technical and clinical success, postprocedural complication and need of additional procedure were analyzed. Results: A total of 111 male and 11 female patients were included. Morphology of the aneurysms was as follows: fusiform (n = 108), saccular (n = 3) and ruptured type (n = 11). Sixty-four patients had hostile neck anatomy. The preprocedural mean sac-diameter was 52.4 mm. Postprocedural sac-diameter was decreased or stable in 110 patients (90.2%) and increased in 8 patients (6.6%). Technical success rate was 100% and clinical success rate was 86.1%. Fifty-one patients showed endoleak (41.8%) and 15 patients (12.3%) underwent secondary intervention due to type I endoleak (n = 4), type II endoleak (n = 4) and stent-graft thrombosis (n = 7). Conclusion: EVAR is a safe and effective therapy for abdominal aortic aneurysm, and it has high technical success and clinical success rate, and low complication rate.
