Filter by:Venous aneurysms are not common in general, but because of the inherent risk of thrombosis in aneurysms, their timely diagnosis and treatment are recommended in most of the current sources. Ten cases of venous aneurysms were diagnosed and managed in our vascular surgery department from October 2018 to January 2024. Patient information was extracted from their files retrospectively.
Most intracranial aneurysms are found accidentally in neurovascular imaging. And these inspection methods are limited by the problems of instrument fixation, radiation, time-consuming, contrast agent toxicity and so on. At present, blood test is an ideal alternative method for early diagnosis. Compared with imaging examination, it is economical, general screening and convenient. Blood test is simple to operate, easy to be accepted by patients, and less invasive. Early screening of aneurysms can be performed.
The goal of this observational study is to compare the measurements of abdominal aorta width via palpation and point of care ultrasound imaging in healthy individuals. The main question[s] it aims to answer are: - Is there a measurement difference in abdominal aorta width in healthy individuals as measured by palpation and point of care ultrasound imaging? - Are palpation measurements and point of care ultrasound imaging measurements reliable when performed by physical therapy researchers? Participants will be asked to have their abdominal area be palpated around the umbilicus and will have ultrasound imaging performed over their abdominal aorta area. It is anticipated participation in the study will take less than 15 minutes. Subjects will be asked to return for a repeat visit within 1 month to determine reliability of measurements.
Proximal type 1A endoleak is a worrying complication after endovascular repair of an abdominal aortic aneurysm (EVAR). The ideal solution is not obvious between relining by FEVAR and endograft explantation. A retrospective french multicentric study was performed between 2010 and 2023 to compare the outcomes and the efficiency of both technics and propose a decision algorithm for the management of type 1A endoleak after EVAR.
The goal of this observational study is to assess the role of the whole exome sequencing (WES) application in patients with giant coronary artery ectasia (CAE) with a high-risk of genetic background. The main question it aims to answer are: - the assessment of role of WES in CAE - the detection of novel pathogenic mutations associated with CAE development
Managing abdominal aortic aneurysms currently relies on diameter assessment with ultrasound. Diameter reproducibility with two-dimensional ultrasound is challenging, and requires experienced operators. A novel automatic three-dimensional ultrasound system has the potential to facilitate more precise diameter measurements than two-dimensional ultrasound. This study aimed to assess the variance of abdominal aortic aneurysm diameter measurements among ultrasound novices and experts by comparing two-dimensional ultrasound with the three-dimensional ultrasound system in a clinical setting. Ten patients under abdominal aortic aneurysm surveillance were examined by 29 ultrasound-operators: 13 experts and 16 novices. The experts were sonographers and physicians highly experienced in abdominal aortic aneurysm ultrasound, and the novices were medical students and junior residents with sparse ultrasound experience.
Ruptured thoracoabdominal aortic aneurysm (TAAA) represents an emergency medical challenge that needs to be treated promptly. Over the past years different endovascular techniques have emerged such as fenestrated or branched endovascular aortic repair (FB-EVAR). However, FB-EVAR is a technique that uses a custom-made device which needs to be manufactured and this process take months, therefore, it could not be used in urgent settings. Off-the-shelf graft stents are pre-made graft stents, which can be used in urgent cases. A retrospective, multicenter cohort study was planned to include patients who underwent endovascular procedures between January 2015 and January 2022 (85 months) to evaluate the technical and survival outcomes of the use of off-the-shelf stent graft, physician-modified endograft and parallel graft technique in endovascular aortic repair of free and contained ruptured TAAA. Data will be collected anonymously and retrospectively, including patient demographics, risk factors, diagnosis and anatomical details, procedure details and post-operative outcomes.
The aim of the study is to analyze the efficacy of the surgical tretment in patients with ascending aortic aneurysm and dilatation. And to assess rate of negative clinical scenarios in non-oparated patients with ascending aortic dilatation
Aortic valve bicuspid disease is the most common congenital heart disease. It affects 0.5-2% of the population and is associated with an increased risk of developing aortic or ascending aortic valve complications. There is no agreement regarding the opportunity for a "prophylactic" simultaneous aortic valve replacement in the case of mild or moderate aortic valve disease in the bicuspid valve, in patients with an indication for replacement of the ascending aorta due to an aneurysm involving its supra-coronary tract. The aim of this study is to evaluate the long-term evolution of mild and moderate aortic valve disease in untreated bicuspid valve during supracoronary ascending aortic replacement surgery at our institution.
The use of intracranial stents expands the possibilities for endovascular treatment of intracranial aneurysms and improves the success rate. However, it also increases the risk of ischemic complications in patients. The current standard dual antiplatelet regimen is considered crucial in reducing thrombotic events. Nevertheless, some patients exhibit resistance to antiplatelet drugs, which puts them at a higher risk of thrombotic events. In clinical practice, there is a lack of standardized platelet function testing and consensus on adjusting antiplatelet drug programs. This study conducted a multi-center, prospective cluster randomized controlled trial to investigate whether antiplatelet adjustment therapy guided by light transmittance aggregometry (LTA) detection can decrease the occurrence of ischemic events after stent implantation in patients with unruptured intracranial aneurysms. Additionally, the study aimed to establish a set of standardized antiplatelet regimens.
