CONTEXT: Abdominal aortic aneurysm is an asymptomatic but potentially fatal condition. Elective surgery can prevent death from rupture, and is indicated for aneurysms larger than 45 mm. Because aneurysms tend to grow with time, detection of small ones (> 29 mm) may lead to a closer follow-up of patients at risk. OBJECTIVE: To determine the prevalence of abdominal aortic aneurysms in São Paulo, Brazil. DESIGN: Prospective, descriptive. SETTING: University Hospital. PARTICIPANTS: Persons aged 50 years or more were offered, through the press, the opportunity to be screened for abdominal aortic aneurysm. The total number screened was 2,756. PROCEDURE: All were submitted to abdominal palpation and ultrasound examination. PARAMETER STUDIED: A maximum diameter of 30 mm or more was considered to be an aneurysm. RESULTS: Sixty-four aneurysms were detected, nine of which measuring more than 49 mm. Palpation detected 60 aneurysms, but only 20 of these were confirmed by the ultrasound. Conversely, 41 of the ultrasound-detected aneurysms were not palpable. The percentages of abdominal aortic aneurysms found in the subgroups via ultrasound examination (with 95% confidence interval) were as follows: total group, 2.3 (1.8-3); men, 4.6 (3.5-5.9); women, 0.6 (0.3-1.1); men aged 60 or more, 6 (4.3-8); women aged 60 or more, 0.9 (0.4-1.8). CONCLUSION: In São Paulo, Brazil, 1.8 to 3 % of persons aged 50 years or more are expected to have abdominal aortic aneurysms. In the subgroup of men aged 60 or more, the expected prevalence is between 4.3 and 8%.

Objective To analyze the characteristics of patients with abdominal aortic aneurysms referred to a tertiary center and to compare with individuals with abdominal aortic aneurysm found at necropsy. Methods We have retrospectively analyzed the medical records of 556 patients with abdominal aortic aneurysm and 102 cases abdominal aortic aneurysm found at necropsy. Results At univariated analysis, hypertension, tobacco use and maximum diameter were significant risk factors for symptomatic aneurysm, while diabetes tended to be a protective factor for rupture. By logistic regression analysis, the largest transverse diameter was the only one significantly associated with abdominal aortic aneurysm rupture ( p < .0001, odds ratio 1.7, 95% confidence interval 1.481–1.951). Intact abdominal aortic aneurysm found at necropsy showed similarities with outpatients in relation to abdominal aortic aneurysm diameter and risk factors. Conclusion Intact abdominal aortic aneurysm at necropsy and at outpatients setting showed similarities that confirmed that abdominal aortic aneurysm repair is less offered to women, and they died more frequently with intact abdominal aortic aneurysm from other causes.

Background: The prevalence of abdominal aortic aneurysms is higher in population with other vascular comorbidities, especially among men. Utility of screening among patients with cerebrovascular disease is unclear. Objective: To determine the prevalence of abdominal aortic aneurysm in male patients with diagnosed cerebrovascular disease manifested by transient ischemic attack or stroke. Material and Methods: Between May 2013 and May 2014, all consecutive male patients undergoing carotid ultrasound in single tertiary center with a catchment area of 179,000 inhabitants were evaluated for ultrasound screening of abdominal aortic aneurysm. Abdominal aortic aneurysm was defined as maximum diameter of infrarenal aorta 30 mm or more. Results: Of 105 (n = 105) consecutively evaluated male patients, only 69% (n = 72) were eligible for the study and underwent aortic screening. Reason for ineligibility was most often poor general medical condition (n = 29). Mean age of screened patients was 66 years (SD 9.8 years). Half of the screened patients suffered stroke (n = 36). The incidence of abdominal aortic aneurysm was 5.6% (n = 4). All found abdominal aortic aneurysms were small and did not require immediate surgical intervention. During a follow-up period of over 4 years, none of the aneurysms exhibited tendency for growth. Conclusion: The male population with cerebrovascular disease is comorbid and frail. Only, moderate prevalence of abdominal aortic aneurysms can be found in this subpopulation.

Abdominal aortic aneurysms are a common health problem and currently the need for surgical intervention is determined based on maximum diameter and growth rate criteria. Since these universal variables often fail to predict accurately every abdominal aortic aneurysms evolution, there is a considerable effort in the literature for other markers to be identified towards individualized rupture risk estimations and growth rate predictions. To this effort, biomechanical tools have been extensively used since abdominal aortic aneurysm rupture is in fact a material failure of the diseased arterial wall to compensate the stress acting on it. The peak wall stress, the role of the unique geometry of every individual abdominal aortic aneurysm as well as the mechanical properties and the local strength of the degenerated aneurysmal wall, all confer to rupture risk. In this review article, the assessment of these variables through mechanical testing, advanced imaging and computational modeling is reviewed and the clinical perspective is discussed.

Abdominal aortic aneurysm (AAA) is a potentially fatal condition with risk of rupture increasing as maximum AAA diameter increases. It is agreed upon that open surgical or endovascular treatment is indicated if maximum AAA diameter exceeds 5 to 5.5cm. Continuing aneurysmal degeneration of aortoiliac arteries accounts for significant morbidity, especially in patients undergoing endovascular AAA repair. Purpose of this review is to give an overview of the current evidence of medical treatment of AAA and describe prospects of potential pharmacological approaches towards prevention of aneurysmal degeneration of small AAAs and to highlight possible adjunctive medical treatment approaches after open surgical or endovascular AAA therapy.

Infectious abdominal aortic aneurysms often present with abdominal and lower back pain, but prolonged fever may be the only symptom. Infectious abdominal aortic aneurysms initially presenting with meningitis are extremely rare; there are no reports of their successful treatment. Cases withStreptococcus pneumoniaeas the causative bacteria are even rarer with a higher mortality rate than those caused by other bacteria. We present the case of a 65-year-old man with lower limb weakness and back pain. Examination revealed fever and neck stiffness. Cerebrospinal fluid showed leukocytosis and low glucose levels. The patient was diagnosed with meningitis and bacteremia caused byStreptococcus pneumoniaeand treated with antibiotics. Fever, inflammatory response, and neurologic findings showed improvement. However, abdominal computed tomography revealed an aneurysm not present on admission. Antibiotics were continued, and a rifampicin soaked artificial vascular graft was implanted. Tissue cultures showed no bacteria, and histological findings indicated inflammation with high leukocyte levels. There were no postoperative complications or neurologic abnormalities. Physical examination, blood tests, and computed tomography confirmed there was no relapse over the following 13 months. This is the first reported case of survival of a patient with an infectious abdominal aortic aneurysm initially presenting with meningitis caused byStreptococcus pneumoniae.

This is the second article in a series of articles regarding screening programmes. In this article, an overview of the abdominal aorta is provided. The article also considers the abdominal aortic aneurysm screening programme. Aortic abdominal aneurysm is described. The majority of abdominal aortic aneurysms are asymptomatic; however, if there are any symptoms, these are explained. All four UK countries offer men aged 65 years and over a screening opportunity using an ultrasound scan, the fundamental aspects of abdominal aortic aneurysm screening programmes is offered. It is emphasised that screening is not mandatory in the UK; the man has a right to decline the invitation to attend any screening programme.

Objective: The aim of our study was to assess the prevalence of renal masses suspected of malignancy and adrenal incidentalomas in patients with abdominal aortic aneurysm based on the computed tomography angiography (CTA). Methods: In the retrospective cross-sectional study, the CTA scans of patients with abdominal aortic aneurysms and thoraco-abdominal aortic aneurysms type II-IV were assessed. Patients with thoraco-abdominal aortic aneurysms type I and V and history of abdominal aortic surgery were excluded from the study. Results: Study group comprised 937 patients with a median age of 73.0 years, 83.8% of whom were male. CTA revealed renal tumors in 11 patients (1.2% of the study population) with a median size of 26 mm (interquartile range 20-50). Adrenal incidentalomas were found in 61 patients (6.5% of the study population). In 20 patients (2.1%) adrenal lesions were found bilaterally. Conclusion: In the described cohort, the renal and adrenal tumors were relatively common findings among patients with abdominal aortic aneurysm and thoraco-abdominal aortic aneurysms type II-IV. Both anaesthesiologists and surgeons should be vigilant about the possibility of such coexistence in order to provide the patients with the best possible perioperative care and an optimal surgical modality.

Objective Endovascular aneurysm repair for ruptured abdominal aortic aneurysm is being increasingly applied as the intervention of choice. The purpose of this study was to determine whether survival and reintervention rates after ruptured abdominal aortic aneurysm vary between endograft devices. Methods This cohort study identified all ruptured abdominal aortic aneurysms performed at The Ottawa Hospital from January 1999 to May 2015. Data collected included patient demographics, stability index at presentation, adherence to device instructions for use, endoleaks, reinterventions, and mortality. Kruskal–Wallis test was used to compare outcomes between groups. Mortality outcomes were assessed using Kaplan–Meier survival analysis, and multivariate Cox regression modeling. Results One thousand sixty endovascular aneurysm repairs were performed using nine unique devices. Ninety-six ruptured abdominal aortic aneurysms were performed using three devices: Cook Zenith ( n = 46), Medtronic Endurant ( n = 33), and Medtronic Talent ( n = 17). The percent of patients presented in unstable or extremis condition was 30.2, which did not differ between devices. Overall 30-day mortality was 18.8%, and was not statistically different between devices ( p = 0.16), although Medtronic Talent had markedly higher mortality (35.3%) than Cook Zenith (15.2%) and Medtronic Endurant (15.2%). AUI configuration was associated with increased 30-day mortality (33.3% vs. 12.1%, p = 0.02). Long-term mortality and graft-related reintervention rates at 30 days and 5 years were similar between devices. Instructions for use adherence was similar across devices, but differed between the ruptured abdominal aortic aneurysm and elective endovascular aneurysm repair cohorts (47.7% vs. 79.0%, p < 0.01). Notably, two patients who received Medtronic Talent grafts underwent open conversion >30 days post-endovascular aneurysm repair ( p = 0.01). Type 1 endoleak rates differed significantly across devices (Cook Zenith 0.0%, Medtronic Endurant 18.2%, Medtronic Talent 17.6%, p = 0.01). Conclusion Although we identified device-related differences in endoleak rates, there were no significant differences in reintervention rates or mortality outcomes. Favorable outcomes of Cook Zenith and Medtronic Endurant over Medtronic Talent reflect advances in endograft technology and improvements in operator experience over time. Results support selection of endograft by operator preference for ruptured abdominal aortic aneurysm.
