Filter by: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.
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.
This project seeks to determine if certain anatomic factors, specifically tortuous and non-conformable iliac arteries, may predict device complications, including seal zone failure, type III endoleak, and occlusion. Approximately 400 subjects from 5 academic centers across the United States, Europe, and Asia will be included in this study. Various markers of pre- and post-treatment iliac anatomy will be measured using CT imaging, and clinical events will be reported by academic centers. The relationship of imaging data to patient demographics will then be assessed alongside anatomic and demographic predictors of non-conformability.
Objective Complex aortic pathology has been revolutionized with the use of hybrid prostheses such as the Thoraflex® Hybrid Frozen Elephant Trunk (FET). The aim of this study was to evaluate the midterm results of secondary extension of the FET by thoracic endovascular aortic repair (TEVAR). Few data are present in the literature regarding the outcomes of this secondary treatment. The investigators perform a prospective study between 2015 and 2022 in a tertiary aortic center on all consecutive patients having undergone TEVAR after FET implantation. The TEVAR endograft covered most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized angiography (CTA) at 6-month and yearly thereafter. The aim of this study was the feasibility of theses secondary connexion and the mid term outcomes of the endovascular treatment.
The purpose of this PMCF study is to evaluate a minimum of 125 subjects in 1 or 2 sites in France at least 1-year follow-up after surgery until a maximum of 5 years in the indication of abdominal and peripheral arterial surgery not crossing the knee flexion crease. the objectives of the evaluation will describe safety and performance of POLYMAILLE® EXTRA THIN.
Purpose of the study is to describe safety and performance of POLYMAILLE® C from a minimum of 200 subjects will be evaluated. A minimum of 100 subjects will be evaluated for each main location of surgery (abdominal and peripheral). Follow-up At least 1 year follow-up after surgery until a maximum of 5 years. POLYMAILLE®C vascular prostheses are indicated for replacement or bypass of arteries presenting aneurysm or obliterative arterial disease. Their indication is restricted to abdominal and peripheral surgery not crossing the knee flexion crease.
The overall aim is to determine the frequency by which women and men with intact abdominal aortic aneurysms (AAA) are treated with elective surgery at three vascular outpatient clinics in Europe, and to investigate whether the reasons to refrain from elective surgery differ between the sexes.
This is a retrospective cohort study of consecutive patients submitted to elective EVAR, between February/2009 and May/2019 in a single institution. Symptomatic or ruptured AAA, mycotic aneurysms, isolated iliac aneurysms and complex abdominal aortic repairs were excluded. The primary outcomes were freedom from secondary intervention and compliance with follow-up, defined as surveillance imaging performed within a periodicity no longer than 18 months.
The aim was to determine, within the patient enrolled in three controlled prospective studies, INNOVATION, INSPIRATION and INSIGHT (Sponsor: Cordis, A Cardinal Health Company) studies which are preoperative and postoperative anatomical risk factors associated to limb occlusion. In the three studies the total number of enrolled patients was 400, of whom 134 enrolled in the US
