“…After reviewing full texts, 34 articles were considered as relevant and 15 were finally included in the scoping review ( Figure 1 ). Briefly, 11 papers focused on EVAR [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ], 3 on FEVAR [ 15 , 16 , 17 ], and 1 on EVAR and FEVAR [ 18 ], including elective and non-elective presentations. Overall, we included 2574 subjects of which 2361 received EVAR and 213 received FEVAR, respectively.…”

“…The perpendicular plane to the longitudinal outer-to-outer axis at the lowest renal artery represented the commonest and more intuitive approach [ 4 , 5 , 6 , 8 , 11 , 12 , 13 , 14 , 17 ]. Several authors extended the measurement 5 mm–20 mm below the renal arteries level or to the suprarenal aorta, at the level of the superior mesenteric artery (SMA) or celiac artery (CA).…”

“…The sole paper comparing outcomes of FEVAR vs. EVAR, included patients with suprarenal and infrarenal fixation endografts. Complete adherence to Instructions for Use (IFU) of aortic endografts was reported in only 5 papers [ 4 , 11 , 12 , 13 , 14 ].…”

“…In the EVAR group, 8 studies reported outcomes after 5 years from the index procedure [ 4 , 6 , 7 , 8 , 10 , 11 , 12 , 14 ]. Incidence of PND depended upon the methods of measurement and the standards of reporting.…”

Background: To define proximal neck dilation (PND) after standard endovascular aneurysm repair (EVAR) and fenestrated EVAR (FEVAR), determining: incidence and risk factors; evidence base that links PND to outcomes of patients; recurring themes or gaps in the literature. Methods: We performed a scoping review and included only full-text English articles with follow-up focusing on PND in patients undergoing EVAR or FEVAR, published between 2000 and 2022. The following PICO question was used to build the search equation: in patients with abdominal-aortic-aneurysm (AAA) (Population) undergoing endovascular repair (Intervention), what are the incidence, risk factors and prognosis of radiologically defined PND (Comparison) on short-term and long-term outcomes (Outcomes)? Results: 15 articles were included after review. Measurement protocols for proximal aortic neck (PAN) varied among individual studies and the definition of PND resulted as heterogeneous. Rate of patients with a PND ranged between 0% and 41%. Large proximal neck (>28 mm) and excessive graft sizing (30%) were predictors for PND. New endografts with low outward radial forces and FEVAR seemed to be protective. Surgical conversion was the definitive option in the case of patients unfit for other endovascular treatments. Conclusions: PND is a frequent finding after EVAR and FEVAR. Excessive graft oversizing and large baseline PAN were predictors of neck enlargement, independently by the type of standard endograft used. FEVAR may be considered protective against complications, together with endografts using low outward radial forces. Lifelong radiological follow-up is mandatory.
