Objectives The aim of this study was to compare image quality, conspicuity, and endoleak detection between single-energy low-kV images (SEIs) and dual-energy low-keV virtual monoenergetic images (VMIs+) in computed tomography angiography of the aorta after endovascular repair. Materials and Methods An abdominal aortic aneurysm phantom simulating 36 endoleaks (2 densities; diameters: 2, 4, and 6 mm) in a medium- and large-sized patient was used. Each size was scanned using single-energy at 80 kVp (A) and 100 kVp (B), and dual-energy at 80/Sn150kVp for the medium (C) and 90/Sn150kVp for the large size (D). VMIs+ at 40 k...
We would like to congratulate Antoniou et al. for their timely overview and meta-analysis, comparing long term outcomes of the randomised trials of open surgical repair (OSR) vs. endovascular aneurysm repair (EVAR).1 The strengths of this review are the inclusion of long term results from the OVER trial, published recently, and early resu lts from a small, but previously unidentified, Chinese randomised trial.2,3
CONCLUSION: Cardiac and extra-cardiac pathologies should be kept in mind in patients with acute arterial occlusion. Thus, detected pathologies could be treated, and the development of additional peripheral emboli could be prevented.RESUMO OBJETIVO: O objetivo do estudo é investigar patologias cardíacas e extracardíacas em pacientes operados por oclusão arterial aguda. MÉTODOS: Entre março de 2010 e março de 2018, um total de 120 pacientes submetidos a tratamento cirúrgico para oclusão arterial aguda foram incluídos neste estudo retrospectivo. RESULTADO S...
This meta-analysis sought to identify the mortality and ambulatory state 30 days and one year post-operatively in octogenarians treated for ruptured abdominal aortic aneurysm (rAAA) by endovascular aneurysm repair (EVAR) or open repair (OR). rAAA is a life threatening emergency occurring increasingly in octogenarians. Surgical treatment, open or endovascular, offers the only chance of survival albeit with significant mortality and morbidity rates and a high burden to society. In order to make an informed decision on management, contemporary treatment outcomes should be known.
CONCLUSION: The 30 day and one year mortality rates for rAAA repair in octogenarians are similar to the outcome at all ages, with a significant survival advantage of EVAR over OR. Patients should therefore not be denied treatment of a rAAA based on age alone. PMID: 31810836 [PubMed - as supplied by publisher]

Introduction - Juxtarenal abdominal aortic aneurysm (JAAA) is defined as an infrarenal AAA that is adjacent to or involving the lower margin of the renal artery origins1. Recently, promising results have been reported in peer reviewed journals after fenestrated and chimney graft approaches to repair of JAAA2,3. Open repair, fenestrated endovascular aneurysm repair (FEVAR) and chimney endovascular aneurysm repair (Ch-EVAR) are effective methods to treat this condition, but the comparative effectiveness of these treatment modalities is unclear4.
Introduction - Reporting standards described by Chaikof in 20021 and by Boyle in 20112 highlighted the need for appropriate aortic morphology analysis to determine abdominal aortic aneurysms (AAA) suitability for endovascular repair (EVAR) and to predict outcomes. Moreover, instructions for use provided by manufacturers to help select patients for EVAR, are mainly based on specific anatomic criteria.
Introduction - The use of fenestrated endovascular aneurysm repair (FEVAR) and branched endovascular aneurysm repair (BEVAR) for the treatment of complex abdominal aortic aneurysms (AAA) is rapidly increasing.1 Successful aneurysm exclusion and prevention of long-term treatment failure need to be balanced against the increased technical complexity and operative risks of more extensive procedures.2 The aim of this study was to analyse the linear relationships between the number of catheterised vessels and various procedural variables for endovascular treatments of complex aortic aneurysms using FEVAR and BEVAR, as compared ...
Introduction - microRNAs (miRs) are small and non-coding RNA molecules that are involved in different biological processes(1). Due to their stability and their presence in biofluids, several investigations have been focused on the use of miRs as biomarkers of different pathologies(2). At this work we tried to identify circulating miRs differentially expressed in patients with abdominal aortic aneurysm (AAA) and healthy donors that could be used as potential biomarkers.
