ABSTRACT: Purpose: To investigate the long term survival benefit for the treatment
of abdominal aortic aneurysmal (AAA) disease with Endovascular Aneurysm Repair
(EVAR). Our hypothesis is that patients undergoing EVAR have an equivalent
survival to an age matched population. Methods: Between 1997 and 2014 all
patients treated for an AAA with EVAR by a single surgeon were prospectively
followed and at 12 monthly intervals ultrasonography was utilised to assess the
size of the aorta after treatment. Data from the Births, Deaths and Marriages
was also collected regarding the survival of these patients. As of 2003 all
patients with AAA were treated electively with EVAR. Results: There were a
total of 145 patients treated with EVAR for AAA during the study period, 143
who survived the 30-day post-operative period. The long-term survival following
EVAR at one year was 95% (95% C.I.: 88% to
97%), at 5 years 56% (95% C.I.: 42% to 64%), and at 10 years 28% (95% C.I.:
17% to 42%). Compared to an age-matched population the EVAR group had a lower
than expected long term survival (P
