ABSTRACT
The objective of these Guidelines is to provide recommendations for the classification, indication, treatment and management of patients suffering from aneurysmal pathology of the visceral and renal arteries. The methodology applied was the GRADE-SIGN version, and followed the instructions of the AGREE quality of reporting checklist. Clinical questions, structured according to the PICO (Population, Intervention, Comparator, Outcome) model, were formulated, and systematic literature reviews were carried out according to them. Selected articles were evaluated through specific methodological checklists. Considered Judgments were compiled for each clinical question in which the characteristics of the body of available evidence were evaluated in order to establish recommendations. Overall, 79 clinical practice recommendations were proposed. Indications for treatment and therapeutic options were discussed for each arterial district, as well as follow-up and medical management, in both candidate patients for conservative therapy and patients who underwent treatment. The recommendations provided by these guidelines simplify and improve decision-making processes and diagnostic-therapeutic pathways of patients with visceral and renal arteries aneurysms. Their widespread use is recommended.

BACKGROUND: The aim of the study was to evaluate the correlation between frailty, measured by the Five-Factor Modified Frailty Index (mFI-5) and mortality and all major adverse events (MAE) in patients who underwent proximal abdominal aortic aneurysm (p-AAA) open surgery (OS). METHODS: Data of all elective patients submitted to p-AAA OS from 2010 to 2021 were recorded. Primary endpoints were 30-day mortality and mid-term survival and secondary endpoints included postoperative acute kidney injury (AKI), freedom from aortic reintervention and any MAE. The impact of frailty was assessed by univariate and multivariate analysis; mid-term overall survival were estimated using Kaplan-Meier method (log-rank test). RESULTS: Two-hundred twenty-one patients (197 male, 24 female; aged 72.2±7.4) were included. Thirty-seven (16.4%) were octogenarians (>80 years). The mFI-5 was assessed in the entire group: mean mFI-5 was 0.29±0.12. One-hundred patients (100/221, 45.25%, 91:9 male-to-female ratio) were defined "frail" considering the mFI-5 cut-off >0.25. At univariate analysis a correlation was found between mFI-5>0.25 and mid-term mortality (Pearson correlation [r] 0.280, P<0.001) and AKI (r=0.146, P=0.030). No correlation with 30-day mortality was found (P not significant). At multivariate analysis mFI-5>0.25 increased the risk for midterm mortality (odds ratio 3.32, P=0.021) and postoperative AKI (OR 2.09, P<0.001). The effect of mFI-5>0.25 on mid-term mortality persisted after adjustment for age (P<0.001). Survival was estimated with Kaplan-Meyer method (mean follow-up of 52.7 months, 95% CI: 48.6-56.8); 68 (30.7%) deaths were recorded: 23 among non-frail patients (19.0%) and 45 among frail patients (45/100, 45%, P<0.001). CONCLUSIONS: These findings suggest that mFI-5 is a tool capable to identify "frail" patients, who appear to be at increased risk of postoperative AKI and mid-term mortality, but not 30-day mortality. Five-factor modified Frailty Index assessment is simple, fast and can be widely applied in surgical practice to perform appropriate risk stratifications.

BACKGROUND: To report our experience with the open repair (OR) of hostile-necked, juxtarenal, pararenal, and suprarenal (SR) aortic aneurysms (proximal abdominal aortic aneurysms) and stratify the results according to the equivalent endovascular repair. METHODS: Data from all patients treated between 2010 and 2015 were prospectively collected and retrospectively reviewed. Preoperative computed tomographic (CT) scans were analyzed to plan a hypothetical equivalent endovascular approach (2, 3, and 4 fenestrations [FENs]). Postoperative results were recorded based on the cross-clamping level: supraceliac (SC), SR, and infrarenal (IR). Major adverse events (MAEs) were defined as the presence of one of the following: all-cause mortality, bowel ischemia, myocardial infarction, paraplegia, respiratory failure, stroke, and renal insufficiency. RESULTS: One hundred fifty-seven patients were treated; 93 met the CT scan criteria (slice thickness, <1.5 mm) and were included in the study. Thirty-day mortality was 2.2% (SC, 7.4%; SR, 0%; IR, 0%) and MAE was 31.2% (SC, 51.9%; SR, 27.3%; IR, 13.6%) in the entire cohort. After endovascular planning, 11 (11.8%) patients would have been treated with a 2-FEN device, 20 3-FEN (21.5%), and 62 4-FEN (66.7%). Only 35.5% of the 4-FEN patients received an SC aortic cross-clamping, whereas 43% SR and 21% IR. Renal/visceral perfusion was performed in 45 (72.5%) 4-FEN patients, and in 20 (64%) 2/3-FEN patients (P < 0.001); renal/visceral revascularization was needed in 23 (37.1%) 4-FEN and 5 (19.2%) 2/3-FEN patients (P = 0.054). CONCLUSIONS: Implementing a fenestrated endovascular aortic repair (FEVAR) endovascular program could reduce MAEs, but it must be clear that FEVAR for juxtarenal disease may overcomplicate treatment and include manipulation of visceral vessels that would not need to be affected if IR clamping is possible in OR, when it gives excellent results.
