Abstract:
Objective:To examine the mid- and long-term outcomes of endovascular aneurysm repair (EVAR).Methods:This was a retrospective cohort study of 540 patients with abdominal aortic aneurysm who received EVAR at Department of Vascular Surgery, The First Affiliated Hospital, Sun Yat-sen University from January 2009 to December 2018. There were 503 males and 37 females, aged of (69±8) years (range: 44 to 87 years). Clinical data including concomitant disease, aneurysm size and surgical data were collected and patients were followed up after operation. The cumulative survival rate was assessed using the Kaplan-Meier estimator and multivariate Cox regression was used to analyze the independent prognosis factors.Results:The technical success rate was 91.1% (492/540). The perioperative mortality rate was 1.3% (7/540) and the follow-up rate was 91.7% (489/533). The median follow-up time was 45(63) months (range: 1 to 133 months). The all-cause mortality rate was 21.3% (104/489) and the aneurysm-related mortality rate was 6.3% (31/489) during follow-up period. The overall cumulative survival rate of 1-, 3-, 5- and 10-year were 95.1%, 84.0%, 69.5% and 38.6%, respectively, while freedom from aneurysm-related death were 98.4%, 93.3%, 88.4% and 84.4%. During the follow-up period, the complications rate was 9.0% (44/489), and the re-intervention rate was 4.9% (24/489). Cox regression analysis showed that elder age ( HR=2.15, 95 %CI: 1.41 to 3.26, P<0.01), preoperative aneurysm rupture ( HR=2.72, 95 %CI: 1.78 to 4.15, P<0.01) and short neck aneurysm ( HR=1.97, 95 %CI: 1.07 to 3.61, P=0.029) were independent prognosis factors for long-term survival after EVAR. Connclusion:EVAR has low perioperative mortality, high technical success rate, and satisfactory mid-and long-term outcomes.
