PURPOSE: To investigate the performance of a new device that uses the STRATA polytetrafluoroethylene graft material and a mechanism that provides active proximal sealing in order to prevent @entity1070 during @entity439 repair (EVAR). METHODS: Between April 2013 and July 2014, 21 consecutive @entity1 (all @entity1 ; median age 71 years, range 60-84 years) with @entity1028 (median diameter 5.9 cm, range 4.9-7.8 cm) and suitable anatomy were offered elective EVAR using the AFX endograft. These @entity1 had an irregular, conical, tapered, or bulging proximal neck, for which this specific device was considered appropriate. @entity439 exclusion and incidence of @entity1070 were the primary outcomes; secondary outcomes included mortality, morbidity, migration, and other graft-related complications. RESULTS: Primary technical success was 90%; 2 intraoperative type Ia endoleaks due to low endograft deployment were treated with additional proximal cuffs. During a median follow-up of 10 months (range 2-15 months), no @entity1070 was observed. One @entity1070 was encountered, with no associated sac enlargement. There was no stent-graft migration or any other device-related complication. One @entity1 had a nonfatal @entity583 and another developed @entity177 requiring transient dialysis. No @entity204 occurred. CONCLUSION: In this early experience, this newly available device appears to be safe and efficient in providing seal along irregularly shaped necks over the short term.
