Endovascular repair of the thoracic aorta.

[Endovascular repair of the thoracic aorta]. Presse Med. 2018 Feb 23;: Authors: Canaud L, Alric P Abstract Degenerative aneurysms of the thoracic aorta are increasing in prevalence. The recognition of the decreased morbidity of this approach compared with open repair was readily apparent, as it avoided left thoracotomy, aortic cross-clamping, and left heart bypass. Repair of isolated descending thoracic aortic aneurysms using stent grafts was introduced in 1995, and in an anatomically suitable subgroup of patients with thoracic aortic aneurysm, repair with endovascular stent graft provides favorable outcomes, with decreased perioperative morbidity and mortality relative to open repair. The cornerstones of successful thoracic endovascular aneurysm repair are appropriate patient selection, thorough preprocedural planning, and cautious procedural execution. Since then, TEVAR is increasingly being used for other aortic pathologies such as complicated type B dissection, traumatic aortic transection, and aneurysmal disease extending into the arch or visceral segment, requiring debranching procedures.

Molecular and genetic bases of thoracic aortic aneurysms mainly include transforming growth factor beta signaling, smooth muscle contractile units and metabolism genes, and extracellular matrix genes. In recent studies, a role of Notch signaling, among other pathways, has emerged ...

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...

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.

Introduction - Endovascular Aneurysm Repair (EVAR) has replaced open surgery in patients with suitable anatomy due to its low perioperative morbidity and mortality rates. In the context of an ageing population, EVAR has become the standard approach to managing aneurysmal disease in the elderly. However, long-term outcomes in older patients are unclear.

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 ...
