New developements in endovascular infrarenal aortic aneurysm treatment.
[New developements in endovascular infrarenal aortic aneurysm treatment]. Radiologe. 2018 Aug 13;: Authors: Maßmann A, Shayesteh-Kheslat R, Frenzel F, Fries P, Bücker A Abstract CLINICAL/METHODICAL ISSUE: New technical developments in endovascular aortic repair (EVAR) have broadened the range of patients eligible for minimally invasive aneurysm treatment. Optimization of delivery sheaths and catheters by considerable downsizing of diameters, increase of pushability and stability combined with flexibility are important parameters. PERFORMANCE: Especially patients characterized by small and tortuous iliac access vessels can nowadays be treated by EVAR. Ease and effectiveness of applicability guarantee safety and quality improvement, which results in better treatment of patients. Progress in stent-graft design with integrated options for repositioning, active positioning and aneurysm sealing facilitate treatment of angulated vessel segments or hitherto unsuitable sealing zones. PRACTICAL RECOMMENDATIONS: Interventionalists have to be familiar with all available stent-graft materials and techniques. Profound knowledge helps to choose the best material for a patient's individual anatomy, confident application and long-term satisfactory results. PMID: 30105534 [PubMed - as supplied by publisher]
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
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 - 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 - Female gender is associated with worse outcome in open as well in endovascular Aortic Aneurysm Repair. Few data are available on the influence of gender on endovascular treatment of thoraco-abdominal aortic aneurysm (TAAA) outcome. The aim of this study was to evaluate the effect of gender on outcome after TAAA endovascular repair using fenestrated and branched endograft (F/B-EVAR).
Introduction - Late survival is similar after open and endovascular abdominal aortic aneurysm repair (EVAR), despite lower perioperative mortality with EVAR1,2. Further re-interventions for graft complications are however more common following EVAR compared with open repair3. Long-term surveillance imaging is required following endovascular treatment to identify and treat complications. A significant proportion of patients have historically been found to become lost to surveillance efforts4 and have previously been found to have worse outcomes as a result 5.
The objective of the current study is to describe the Dutch experience with relining a failed open or endovascular AAA with EVAS.
Introduction - Aim of this study was to evaluate results of the endovascular repair (EVAR) for abdominal aortic aneurysm (AAA) using the AnacondaTM endograft at 5 years of follow up.
