Abstract
Abdominal aortic aneurysm (AAA) is defined as abnormal dilation of the infrarenal abdominal aortic diameter to 3.0 cm or greater. The natural history of AAA consists of progressive expansion and potential rupture. Although most AAAs are clinically silent, a pulsatile abdominal mass identified on physical examination may indicate the presence of an AAA. When an AAA is suspected, an imaging study is essential to confirm the diagnosis. This document reviews the relative appropriateness of various imaging procedures for the initial evaluation of suspected AAA. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Leone N, Broda MA, Eiberg JP, Resch TA. Systematic Review and Meta-Analysis of the Incidence of Rupture, Repair, and Death of Small and Large Abdominal Aortic Aneurysms under Surveillance. J Clin Med 2023; 12:6837. [PMID: 37959301 PMCID: PMC10648148 DOI: 10.3390/jcm12216837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND The ultimate goal of treating patients with abdominal aortic aneurysms (AAAs) is to repair them when the risk of rupture exceeds the risk of repair. Small AAAs demonstrate a low rupture risk, and recently, large AAAs just above the threshold (5.5-6.0 cm) seem to be at low risk of rupture as well. The present review aims to investigate the outcomes of AAAs under surveillance through a comprehensive systematic review and meta-analysis. METHODS PubMed, Embase, and the Cochrane Central Register were searched (22 March 2022; PROSPERO; #CRD42022316094). The Cochrane and PRISMA statements were respected. Blinded systematic screening of the literature, data extraction, and quality assessment were performed by two authors. Conflicts were resolved by a third author. The meta-analysis of prevalence provided estimated proportions, 95% confidence intervals, and measures of heterogeneity (I2). Based on I2, the heterogeneity might be negligible (0-40%), moderate (30-60%), substantial (50-90%), and considerable (75-100%). The primary outcome was the incidence of AAA rupture. Secondary outcomes included the rate of small AAAs reaching the threshold for repair, aortic-related mortality, and all-cause mortality. RESULTS Fourteen publications (25,040 patients) were included in the analysis. The outcome rates of the small AAA group (<55 mm) were 0.3% (95% CI 0.0-1.0; I2 = 76.4%) of rupture, 0.6% (95% CI 0.0-1.9; I2 = 87.2%) of aortic-related mortality, and 9.6% (95% CI 2.2-21.1; I2 = 99.0%) of all-cause mortality. During surveillance, 21.4% (95% CI 9.0-37.2; I2 = 99.0%) of the initially small AAAs reached the threshold for repair. The outcome rates of the large AAA group (>55 mm) were 25.7% (95% CI 18.0-34.3; I2 = 72.0%) of rupture, 22.1% (95% CI 16.5-28.3; I2 = 25.0%) of aortic-related mortality, and 61.8% (95% CI 47.0-75.6; I2 = 89.1%) of all-cause mortality. The sensitivity analysis demonstrated a higher rupture rate in studies including <662 subjects, patients with a mean age > 72 years, >17% of female patients, and >44% of current smokers. CONCLUSION The rarity of rupture and aortic-related mortality in small AAAs supports the current conservative management of small AAAs. Surveillance seems indicated, as one-fifth reached the threshold for repair. Large aneurysms had a high incidence of rupture and aortic-related mortality. However, these data seem biased by the sparse and heterogeneous literature overrepresented by patients unfit for surgery. Specific rupture risk stratified by age, gender, and fit-for-surgery patients with large AAAs needs to be further investigated.

Abstract
Abdominal aortic aneurysm (AAA) is defined as aneurysmal dilation of the abdominal aorta to 3 cm or greater. A high degree of morbidity and mortality is associated with AAA rupture, and imaging surveillance plays an essential role in mitigating the risk of rupture. Aneurysm size and growth rate are factors associated with the risk of rupture, thus surveillance imaging studies must be accurate and reproducible to characterize aneurysm size. Ultrasound, CT angiography, and MR angiography provide an accurate and reproducible assessment of size, while radiographs and aortography provide limited evaluation. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
The purpose of this article is to familiarize radiologists and clinicians with a subset of common and uncommon incidental findings on abdominal and pelvic computed tomography examinations, including hepatic, splenic, renal, adrenal, pancreatic, aortic/iliac arterial, gynecological, and a few other miscellaneous findings, with an emphasis on "incidentalomas" discovered in the emergency setting. In addition, we will review the complex problem of diagnosing such entities, and provide current management recommendations. Representative case examples, which we have encountered in our clinical practices, will be demonstrated.

Abstract
Contexto Os aneurismas de aorta abdominal (AAAs) são os mais comuns. A incidência anual de ruptura do AAA é de oito casos por 100.000 habitantes. A detecção incidental pode beneficiar o paciente, desde que o diâmetro seja monitorado e o paciente receba o tratamento adequado. Objetivos Estimar a prevalência do diagnóstico incidental de aneurisma de aorta torácica (AAT) e de AAA em tomografias computadorizadas (TCs); avaliar a prevalência de sexo e idade dos pacientes e determinar quais as artérias acometidas e as características morfológicas dos aneurismas; determinar quais as indicações de TC mais associadas ao diagnóstico incidental de aneurismas. Métodos Estudo descritivo, retrospectivo e randomizado. Critérios de inclusão: pacientes com 50 anos ou mais submetidos a TC de tórax, abdome ou pelve. Critérios de exclusão: acompanhamento ou suspeita diagnóstica de aneurismas. Foram utilizados protocolos com questões sobre dados demográficos e anatômicos. Resultados Foram analisados 1.202 laudos radiológicos. Detectados 27 aneurismas (prevalência de 2,2%). Pacientes: 60% do sexo masculino e 40% do sexo feminino (p < 0,05). Localização: 13 casos (48,2%) na aorta ascendente (AAT); 7 (25,9%) na aorta infrarrenal (AAA); 2 (7,4%) aorta na transição toracoabdominal (ATA); 2 (7,4%) na ilíaca comum; 1 (3,7%) na ilíaca interna; 1 (3,7%) na artéria esplênica; e 1 (3,7%) na artéria renal. Conclusões A maioria dos pacientes foi do sexo masculino (60%); houve maior frequência de AAT (diâmetro médio de 4,1 cm), seguido de AAA (diâmetro médio de 4,0 cm) e ATA (diâmetro médio de 3,9 cm). A principal indicação para a realização de TC associada ao diagnóstico incidental de aneurismas foi em função de sintomas respiratórios.

Abstract
We are presenting a case of one of the largest un-ruptured abdominal aortic aneurysm ever reported. Presented here is a rare case of a 69-year-old active smoker male with history of hypertension and incidental diagnosis of abdominal aortic aneurysm of 6.2 cm in 2003, who refused surgical intervention at the time of diagnosis with continued smoking habit and was managed medically. Patient was subsequently admitted in 2012 to the hospital due to unresponsiveness secondary to hypoglycemia along with diagnosis of massive symptomatic pulmonary embolism and non-ST elevation myocardial infarction. With the further inpatient workup along with known history of abdominal aortic aneurysm, subsequent computed tomography scan of abdomen pelvis revealed increased in size of infrarenal abdominal aortic aneurysm to 9.1 cm of without any signs of rupture. Patient was unable to undergo any surgical intervention this time because of his medical instability and was eventually passed away under hospice care.

Abstract
We aimed to evaluate the frequency, clinical profiles and outcomes of abdominal aortic aneurysms (AAA), and their association with coronary artery disease (CAD) in a small country with high cardiovascular burden. Methods. Data were collected for all adult patients who underwent abdominal computed tomography scans at Hamad General Hospital in Qatar between 2004 and 2008. Results. Out of 13,115 screened patients for various reasons, 61 patients (0.5%) had abdominal aneurysms. The majority of AAA patients were male (82%) with a mean age of 67 ± 12 years. The incidence of AAA substantially increased with age reaching up to 5% in patients >80 yrs. Hypertension was the most prevalent risk factor for AAA followed by smoking, dyslipidemia, renal impairment, and diabetes mellitus. CAD and peripheral arterial disease (PAD) were observed in 36% and 13% of AAA patients, respectively. There were no significant correlations between CAD or PAD and site and size of AAA. Conclusion. This is the largest study in our region that describes the epidemiology of AAA with concomitant CAD. As the mortality rate is quite high in this high risk population, routine screening for AAA in CAD patients and vice versa needs further studies for proper risk stratification.
