PURPOSE: To assess the feasibility and safety of the @entity439 sealing (EVAS) technique in the treatment of acute @entity1028 ( @entity1028 ). METHODS: A retrospective, multicenter, observational study was conducted at 8 centers (7 European and 1 in New Zealand) experienced with EVAS in the elective setting. From February 2013 to April 2015, 58 @entity1 (mean age 74  9 years; 46 @entity1 ) with an acute @entity1028 were treated (28 ruptured and 30 symptomatic). The primary endpoint of the study was 30-day mortality; secondary endpoints included endoleak, reinterventions, and 30-day morbidity. RESULTS: The overall intensive care unit and hospital stays were 2.2  6.6 days and 9.7  11.4 days, respectively. Thirty-day mortality rates were 32% (9/28) for the ruptured group and 7% (2/30) for the symptomatic group, with morbidity rates of 57% and 17%, respectively. Early endoleak was present in only 2 (3%) @entity1 , one in each group; both leaks were type Ia. Reinterventions within 30 days were performed in 8 @entity1 in the ruptured group; in the symptomatic @entity1 , the only perioperative reintervention was embolization a type Ia endoleak. The mean follow-up was 9.3  3.1 months in the ruptured group and 12.4  5.4 months in the symptomatic group. The mean @entity439 diameter at 30-day follow-up was 71.8  16.0 mm compared with 74.7  15.7 mm preoperatively in the ruptured group and 66.1  13.5 mm compared with 65.8  13.0 mm in the symptomatic group. CONCLUSION: EVAS in the acute setting appears safe and feasible and concordant with the literature for @entity439 repair. More robust prospective and comparative data are required to establish the position of the technique in the treatment algorithm of acute @entity1028 .
