Background: This review aims to collect all available data on early and late outcomes in patients undergoing fenestrated endovascular aortic aneurysm repair (F-EVAR) for pararenal or juxtarenal abdominal aortic aneurysms (AAAs).
Methods: The Pubmed, Embase, Scopus and Cochrane Library databases were systematically searched to identify eligible studies. Studies reporting at least early mortality after F-EVAR in patients with pararenal or juxtarenal AAA were included. Thirty-day outcomes were defined as early, and outcomes reported after 30 days postoperatively were defined as late. Basic characteristics of all studies and demographics of patients were reported.
Results: Overall, 30 studies (17 retrospective and 13 prospective) including 23,385 patients in total were included. Out of 23,385 patients, a total of 2,271 patients were treated with F-EVAR for pararenal/juxtarenal AAA. Overall, 4,216 target vessels were to be treated (data from 24 studies). Pooled early mortality reached 2.55% (ranging from 0% to 6.74%), with a pooled technical success of 96.8% (ranging from 82.8% to 100%). Regarding late outcomes, pooled all-cause mortality reached 17% (ranging from 0% to 50%), 1-year primary patency was 94.6% (ranging from 91.8% to 97.1%) and reintervention rate was 10.4% (ranging from 0% to 57.4%). Mean/median follow-up ranged from 3 to 60 months.
Conclusions: Early outcomes indicate that F-EVAR is a safe and efficient treatment for patients with pararenal/juxtarenal AAAs. Although long-term outcomes are acceptable, late-intervention rate remains high.
