Midterm outcomes of endovascular repair for infrarenal abdominal aortic aneurysms
Main Article Content
Abstract
Objective: This study was performed to evaluate the mid-term outcomes of endovascular aneurysm repair (EVAR) in the treatment of infrarenal abdominal aortic aneurysms (AAA).
Materials and method: This is a prospective study. All cases of infrarenal AAA were treated by EVAR at Vascular surgery Department, Cho Ray Hospital from May-2012 to August-2017.
Results: A total of 95 cases (71 males and 24 females) were eligible for inclusion in the study. The mean age was 73,8 ± 17,6. The mean follow-up time was 33 ± 19 months. The rate of late endoleak was 6,3%. There was no case of graft migration and 6 cases requiring re-intervention. The mid-term mortality rate was 21.1% of which 2 cases (2.1%) were related to aneurysms.
Conclusion: The mid-term mortality rates and re-intervention rates of EVAR were both equal or higher than that of conventional surgery. Thus, EVAR is very beneficial in elderly patients associated with comorbidities and risk factors.
