Clinical StudyA Decade of Outcomes and Predictors of Sac Enlargement after Endovascular Abdominal Aortic Aneurysm Repair Using Zenith Endografts in a Japanese Population
Section snippets
Patients
Between July 1999 and August 2011, 127 patients underwent elective EVAR with Zenith endografts. This was a retrospective review of prospectively collected clinical follow-up and imaging data and did not require institutional review board approval according to our institutional guidelines. All patients provided written informed consent to participate in all procedures associated with the study. The median age of patients was 78 years (range, 55–91 y), and the median follow-up time was 43 months
Results
Friendly necks were present in 83 (65%) patients, and hostile necks were present in 44 (35%) patients. Among patients with hostile necks, 31 (25%) had one hostile feature, and 13 (10%) had two hostile features. Table 2 summarizes the demographics and anatomic characteristics of the patients. There were 5 patients lost to follow-up, and 23 patients did not undergo CT imaging at the final visit.
Discussion
This article describes the long-term follow-up results of our single-center experience with the Zenith endograft as elective treatment for AAAs and aortoiliac aneurysms in a Japanese population. Overall 5-year and 10-year survival rates were 77% and 39%, respectively, and 5-year and 10-year rates of freedom from aneurysm-related mortality were 99% and 93%, respectively. Most deaths were unrelated to aneurysms. This finding is comparable to previously reported aneurysm-related mortality rates of
