Aim of this study is to evaluate long-term results in abdominal aortic aneurysm (AAA) surgery by either open aortic repair (OAR) or endovascular aortic repair (EVAR) in patients under 70 years of age.A retrospective analysis of a prospectively collected database of patients with age under 70 years old undergoing elective infrarenal AAA surgery between 2010 and 2018 was performed. The study population was divided into 2 groups: OAR and EVAR. Primary end points were overall survival and aneurysm-related death, while secondary outcomes were need for reintervention and development of minor and major complications.One hundred ninety-one patients younger than 70 years old treated with elective AAA surgery were enrolled: 157 OAR (98% males, mean age 65 ± 4 years) and 34 EVAR (94% males, mean age 66 ± 4 years). Hospital stay, 30-day mortality, and need for reintervention were similar; OAR population presented higher incidence of postoperative major complications (18% vs. 2.9%; P = 0.01) while minor complications were 32% in the OAR versus 21% in the EVAR group (P = 0.08). Median follow-up was 69 months for OAR (interquartile range [IQR] 53 months) vs. 79 months (IQR 51 months) for EVAR (P = 0.9): long-term AAA-related reinterventions were more frequent after EVAR (1.9% OAR vs. 17% EVAR; P = 0.01) while AAA-related long-term mortality was similar in both subgroups (1.3% OAR and 3% EVAR; P = 0.8). At univariate analysis higher risk of reintervention was reported for conical necks in the EVAR group (P = 0.03) and for the concomitant presence of iliac aneurysms in both groups (P = 0.01).According to our data, EVAR in young patients is presenting an excessive rate of reintervention compared to OAR. The presence of conical neck is an independent predictor of EVAR failure and late reintervention, while it does not play a significant role in the OAR group. Open surgery should be considered the first option in younger patients with a long-life expectancy.

Purpose: We present the results of unconventional endovascular treatment of a voluminous (65 mm) saccular visceral aortic aneurysm in a 78-year-old woman. Patient was deemed unfit for open surgery due to comorbidities. Fenestrated or branched endografting was also excluded due to the small diameter of the aorta, the severe stenosis at the origin of celiac trunk, and the anomalous origin of superior mesenteric artery arising infrarenally. Case Report: After a preliminary selective angiography of the superior mesenteric artery showing valid anastomotic network with celiac trunk branches, an aortic self-expandable bare stent (Jotec E-XL) was deployed in the visceral aorta. Aneurysm sac embolization (Penumbra detachable Ruby Coils) in a coil-jailing technique was performed. Finally, an aortic cuff endograft (Gore) was deployed immediately above the origin of the left renal artery to cover the wide neck of the saccular aneurysm and improve sac exclusion. Hospital stay was uneventful, computed tomography (CT) at 12-month demonstrated aneurysm shrinkage to 62 mm without images of endoleak. Literature review showed how this technique has successfully been applied to manage similar cases of postsurgical and posttraumatic saccular aortic aneurysms in high-risk patients; however, long-term results are still unknown. Conclusion: Coil-jail technique for the treatment of saccular aortic aneurysms can be considered an alternative when open surgery or conventional endovascular treatment is not feasible. Technical success and mid-term outcomes are promising but strict follow-up is recommended. Clinical Impact This study aims to share the unconventional endovascular treatment of a visceral aortic aneurysm in a patient unfit both for open and traditional endovascular surgery. To the best of our knowledge this is one of the first cases published in Literature, for this reason, a step-by-step video has been created to describe the procedure. Literature review was then performed to analyze midterm results of this technique. Despite being a treatment that is not recommended for conventional cases, the knowledge of endovascular devices and techniques may help to manage or simplify complex aortic diseases.
