The aim of this study was to perform a meta-analysis of relevant published literature to investigate the impact of wide proximal aortic neck diameter on outcomes of endovascular aneurysm repair (EVAR) for the repair of abdominal aortic aneurysm (AAA).
A systematic literature review was performed to examine the rate of clinical safety and effectiveness end points associated with wide proximal aortic neck diameter after EVAR for the treatment of AAA. A literature search was performed on August 9, 2019, using PubMed as the primary database and Cochrane as the secondary database. In all, there were 11 full articles included in the quantitative and qualitative analyses. There was a total of 7448 patients who were treated for AAA with EVAR. Of these, 26.9% of patients were defined as having wide necks by the individual publications. The definition of wide neck varied in the literature and ranged from 25 mm or greater to 30 mm or greater. The percentage of male patients was 89.1% in the included articles.
