BACKGROUND: Endovascular repair of abdominal aortic aneurysm (EVAR) presents an increasing role in treatment of abdominal aortic aneurysms in patients at high and mid risk for conventional surgery. Most Vascular Surgery Units need to identify a single device as workhorse in AAA treatment. Objective of this study is to analyze midterm results of consecutive unselected patients treated with the same device in a single center series.
METHODS: A retrospective analysis of a prospective database of all consecutive patients treated between January 2016 and June 2019 with the TREO device in our center. Primary outcomes of the study were AAA related mortality rate, migration rate and type 1 endoleak at 1-year follow-up.
RESULTS: During the study period 71 consecutive patients (96% male) were treated with TREO device. Technical success was achieved in all patients. Mean follow-up was 19.6 months (range: 1-42 months). Procedure related mortality was 1.4% (N.=1), No AAA related mortality, migration or type 1b endoleak were recorded during follow-up. Two cases of late type 1a endoleak were recorded, both resolved with aortic cuffing. Median shrinkage of the residual sac was 10% and 18.5% at 6 and 18 months, respectively.
CONCLUSIONS: EVAR using TREO device seems to be safe and effective treatment for unselected patients suffering AAA. Particularly this device seems to be suitable as workhorse device in a single center with skillness between open and endovascular techniques.
