Suprarenal aneurysm

OBJECTIVE: To report a medically treated case of infective aortitis with mycotic aneurysms that went on to have many years of surveillance imaging. This has not yet been documented as current recommendations for infective aortitis strongly suggest operative intervention combined with aggressive antibiotics, with very high reported mortality for non-operative management. Thus, the natural progression of sac growth during the acute infective period and in the long-term has had an opportunity to be explored...

(1) Background: Several mortality risk scores have been developed to predict mortality in ruptured abdominal aortic aneurysms (rAAAs), but none focused on intraoperative factors. The aim of this study is to identify intraoperative variables affecting in-hospital mortality after open repair and develop a novel prognostic risk score. (2) Methods: The analysis of a retrospectively maintained dataset identified patients who underwent open repair for rAAA from January 2007 to October 2023 in three Italian tertiary referral centers...

OBJECTIVE: To evaluate the long-term outcomes of standard endovascular aneurysm repair (S-EVAR) of juxtarenal abdominal aortic aneurysms (JAAAs). METHODS: Data of patients with JAAAs who were unsuitable for fenestrated endovascular aneurysm repair (F-EVAR) and open repair (OR) and underwent treatment from January 2015 to December 2021 were retrospectively reviewed. Computed tomography angiography and ultrasonography of the aorta were performed before discharge, at 6 and 12 months postoperatively, and annually thereafter...

BACKGROUND: Syphilis, owing to its natural course, can lead to long-term damage to the aortic valve, such as insufficiency and rarely stenosis, ostial coronary stenosis, and syphilitic aortitis. Cardiovascular involvement alongside neurological involvement dominates the prognosis. This should no longer be seen, thanks to awareness and prevention programmes, medical treatment, and antibiotics. CASE SUMMARY: We report a case of a 54-year-old chronic smoker with no previous history, admitted for respiratory distress amid an impaired general condition...

OBJECTIVE: This study aims to present the medium-term outcomes of Extra-Design engineering endografts with inner branches (EDE-iBEVARs, Artivion) in endovascular aortic repairs of complex aneurysms building upon promising early results. METHODS: A retrospective, international, multi-centre study was conducted including consecutive patients who underwent complex endovascular aortic repairs using EDE-iBEVARs between 2018 and 2022. Patient demographics, aneurysm anatomical features, procedural details, reinterventions, complications, and endograft failures during follow-up were assessed...

Explantation of traditional infrarenal aortic endografts has been previously described, and explanation of aortic endografts with standard suprarenal fixation at our center has been well defined. However, to the best of our knowledge, no cases have been reported on explantation of endografts with polymer rings present to facilitate the proximal seal. By obtaining full thoracoabdominal exposure with supraceliac clamping and opening the entire aorta along the graft, we were able to successfully explant the ALTO stent graft with polymer rings...

OBJECTIVES: The aim of this study was to assess whether the ratio of the mean infrarenal neck diameter to the suprarenal aortic diameter is a predictor for a durable proximal seal after endovascular aneurysm repair (EVAR). METHODS: A total of 439 patients who underwent elective EVAR between 2004 and 2018 in a single vascular referral center met our inclusion criteria. Ratios were calculated by dividing the mean infrarenal neck diameter by 4 different suprarenal aortic diameters...

PURPOSE: To describe the semibranch as new tool to treat patients with thoracoabdominal, para- and juxtarenal aortic pathologies. TECHNIQUE: The technique is demonstrated in 2 patients with aortic pathologies. First, a 76-year-old woman with a type Ia endoleak after endovascular repair of abdominal aneurysm (EVAR). Due to the short mainbody of the EVAR and suprarenal extension of the pathology, a 4-branched device with integrated bifurcation was chosen. To realize a branched device in small diameters of the suprarenal aorta, 2 semibranches, for the superior mesenteric artery (SMA) and the celiac trunc (CT), were planned...

New-onset acute type B aortic dissection after prior endovascular aneurysm repair is extremely rare. Extension of an aortic dissection can cause destabilization of the previously implanted stent graft, thrombosis of the stent graft, and rupture of the aneurysmal sac, with high mortality without therapy. This report describes the case of a 66-year-old patient complaining of sudden abdominal pain radiating to both flanks. Computed tomography angiography of the aorta revealed acute type B aortic dissection with infrarenal rupture of the false lumen after endovascular abdominal aneurysm repair 5 years prior...

OBJECTIVE: To report on the recommendations of an expert-based consensus on the indications, timing, and techniques of aortic balloon occlusion (ABO) in the management of ruptured abdominal aortic aneurysms (rAAA). METHODS: Eleven facilitators created appropriate statements regarding the study issues that were voted on using a 4-point Likert scale with open-comment fields, by a selected panel of international experts (vascular surgeons and interventional radiologists) using a 3-round modified Delphi consensus procedure (study period: January-April 2023)...

The rupture of an abdominal aortic aneurysm (AAA) causes about 200,000 deaths worldwide each year. However, there are currently no effective drug therapies to prevent AAA formation or, when present, to decrease progression and rupture, highlighting an urgent need for more research in this field. Increased vascular inflammation and enhanced apoptosis of vascular smooth muscle cells (VSMCs) are implicated in AAA formation. Here, we investigated whether hydralazine, which has anti-inflammatory and anti-apoptotic properties, inhibited AAA formation and pathological hallmarks...

BACKGROUND: To perform a systematic review on contemporary outcomes of endovascular repair and open surgical repair (OSR) for the treatment of mycotic aortic aneurysm (MAA). METHODS: A comprehensive literature search on the management of MAAs with endovascular repair or OSR was performed between January 1998 and January 2023. Patient demographics, early and late outcomes were analyzed with respect to treatment modality and MAA location. RESULTS: Forty-eight articles were included, encompassing a total of 1,358 patients (75...

OBJECTIVES: Aortic diameters may differ significantly between patients with different gender and body size. The aim of this study was to relate absolute aortic diameters to age, sex, height, and weight of the patients and to correct for these factors by calculating the ratio between the infrarenal and the suprarenal aortic diameters. METHODS: A total of 458 patients who underwent elective endovascular aneurysm repair (EVAR) between 2004 and 2018 were included. The aortic anatomy in this group of elective EVAR patients was compared with a control group of 75 patients without an abdominal aortic aneurysm (AAA)...

OBJECTIVES: Complex endovascular juxta-, para- and suprarenal abdominal aortic aneurysm repair (comEVAR) is frequently accomplished with commercially available fenestrated (FEVAR) devices or off-label use of aortoiliac devices with parallel branch stents (chEVAR). We sought to evaluate the implantable vascular device costs incurred with these procedures as compared to standard Medicare reimbursement to determine the financial viability of comEVAR in the modern era. METHODS: Five geographically distinct institutions with high-volume, complex aortic centers were included...

Secondary rupture is a late complication of endovascular aneurysm repair (EVAR). Open surgery is a technically feasible treatment option in most cases, however, late conversion carries a significant risk of morbidity and mortality, as it usually requires at least partial explantation of the in situ device, which is of major concern especially if suprarenal fixation is present. Endovascular treatment of these cases is usually challenging, especially since the custom-made devices that are often needed are not readily available but having a production time of several weeks...

OBJECTIVE: Suprarenal bare metal stent separation is a rare complication after endovascular aneurysm repair. In this report, two new cases of this type of device failure are presented and the literature is reviewed to identify similar cases and evaluate associated clinical characteristics. METHODS: A literature search was conducted in March 2022 using PubMed, Embase, and The Cochrane Library, with MeSH terms including aortic aneurysm, stents, and device failure...

INTRODUCTION: Studies comparing male and female patients with abdominal aortic aneurysms have shown that female patients are generally older and more often experience postoperative complications after endovascular and open repair. There are also indications that female patients have more extensive neck pathologies and that they more often have postoperative complications related to proximal neck pathology. MATERIAL AND METHODS: This retrospective study describes all consecutive female patients who underwent EVAR between 1 January 2012 and 31 December 2021...

BACKGROUND: Acute kidney injury (AKI) after endovascular aortic aneurysm repair (EVAR) is uncommon though carries significant morbidity. Procedural risk factors are not well established for acute renal failure (ARF) that requires initiation of dialysis. The goal of this study was to examine the impact of ARF on patients undergoing EVAR and identify risk factors for ARF using a large, national dataset. METHODS: Patients undergoing EVAR were identified from the National Surgical Quality Improvement Program (NSQIP) database over 9 years, ending in 2019...

BACKGROUND: There is significant debate regarding the existence of sex-related differences in the presentation, treatment, and outcomes of men versus women affected by abdominal aortic aneurysm (AAA). The purpose of this study is to compare endovascular aneurysm repair (EVAR) of infrarenal AAAs with the current sex-neutral 5.0-5.5 cm-diameter threshold for intervention between the two sexes. METHODS: Retrospective review of consecutive cases from a single teaching institution over a period of five years of patients who had undergone elective EVAR for AAAs between 5...

Here, we showed our clinicopathological findings of infected aortic aneurysm (IAA) with Pasteurella multocida, which is a Gram-negative coccobacillus and is part of the normal oral flora of many animals. The patient was a 76-year-old male animal owner with a history of diabetes mellitus, alcoholic liver damage, and laryngeal cancer. He died 16 days after admission without undergoing operation because of poor general condition. Autopsy showed saccular outpouching with loss of the existing aortic wall and marked neutrophilic infiltration in the suprarenal abdominal aorta...
