Filter by:In the spirit of improving patient safety and quality of healthcare in our region, the Dallas-Fort Worth Hospital Council Education and Research Foundation (Foundation) and Baylor Research Institute sought and obtained federal funding support (AHRQ grant) to develop an Abdominal Aortic Aneurism (AAA) surgery registry in North Texas. Participating centers will directly benefit from this project and will have access to a de-identified version of the registry data through their collaboration. These data may be used for quality improvement initiatives and/or to conduct your own research. In summary, this effort represents a substantial investment (with no costs to facilities) in improving outcomes for patients with AAA.
This is a prospective study conducted on a population with an aortic endoprosthesis in the context of an abdominal aortic aneurysm. The study's objective is to standardize the ultrasound methodology in the monitoring of aortic endoprosthesis in immediate post-operative care by comparing the results with CT-scan (gold standard). To improve ultrasound methodology, the investigators propose to use the VESMA protocol for ultrasound diameter measurement at four incidences. In addition, the use of ultrasonic contrast agents increases the accuracy of vascular structures, the quality of the ultrasound blood flow image and the duration of signal enhancement. This makes it possible to visualize small gauge vessels and those with slow flows. In this way, the investigators could improve the ultrasound technique for measuring aneurysm bag diameters and endoleak detection. Moreover, the toxicity of iodinated contrast agents is the third cause of acute renal failure in hospitalized patients and is all the more frequent when the investigators increase injections. Improving the quality of ultrasound investigations for the monitoring of aortic endoprosthesis would therefore allow us to reduce the number of CT-scan performed in this population and thus reduce irradiation and the injection of nephrotoxic products. Thereby, the investigators would like to integrate the technique into the systematic follow-up of patients who have benefited from the placement of an aortic endoprosthesis by replacing the CT-scan.
Pre-market, single-arm, prospective, open-label, multi-center clinical trial aimed at assessing the safety and the performance of the Medyria TrackCath system in patients undergoing endovascular intervention.
Both abdominal aortic aneurysm (AAA) and carotid artery stenosis (CAS) are frequent clinical entities, with major morbidity and mortality. This project obtains robust data on the prevalence of AAA and CAS in the Brussels Capital Region. Using duplex ultrasound, a low invasive examination, we want to obtain information on a vast sample of men and women of the Brussels capital region, starting at the age of 60. With these data we can have a far better view on the Belgian situation of these two main vascular clinical entities. The data can provide insights on if, and how, Belgian public health policy can be improved concerning AAA and CAS.
Abdominal aortic aneurysm (AAA) repairs registered in the hospitals administrative database of the National Health Service from 2000 to 2015 were retrospectively analyzed regarding demographics (age and gender) and type of repair (open surgery [OS] or endovascular repair [EVAR]). Rate and mortality were compared among three time periods: 2000-2004, 2005-2009 and 2010-2015.
The incidence of delirium following open abdominal aortic aneurysm (AAA) surgery is significant, with incidence rates ranging from 12 to 33%. The occurrence of delirium on the surgical ward after intensive care unit (ICU) dismissal in AAA patients remains unclear. Differences in outcomes between a delirium on the ICU and a delirium on the surgical ward have not been previously investigated. Delirium is a frequent complication in patients who underwent open AAA surgery. This study demonstrated that patients on the surgical ward remain at risk for developing a delirium after ICU dismissal. Physicians should therefore maintain a high level of awareness for delirium in AAA patients who return to the surgical ward after ICU dismissal. This simultaneously emphasises the necessity of delirium preventive measures and early recognition on the surgical ward in order to improve clinical outcomes.
This is an observational retrospective cohort study of all patients consecutively submitted to elective abdominal aortic aneurysm surgery repair at a tertiary referral centre between 2009 and 2015. Patients were excluded if they were non-elective cases or had complex aortic aneurysms (juxta-renal, thoraco-abdominal or thoracic). Differences between both groups of repair were assessed, as well as short- and long-term complications including medical complications, duration of hospital stay, major cardiovascular events, mortality and vascular reintervention.
This study aims to measure the radiation safety climate in the hybrid angiography suite using self-assessment and to investigate the relationship of radiation safety climate with their self-reported safety behaviors. The hypothesis is that a radiation safety climate does exist and can be measured using self-assessment. Additionally, it is expected that the radiation safety climate positively influences radiation safety behaviors.
In situ fenestration (ISF) could represent an alternative in the treatment of aorto-iliac disease when usual techniques are not available. The aim of this study was to present the results of ISF in aorto-iliac disease. Data will retrospectively be analyzed. Inclusion criteria will be: a surgical abdominal aortic aneurysm (AAA) with an unsuitable anatomy for a standard endograft, aorto-iliac occlusion with narrow distal aorta (<14mm). Technically, after placement of the endograft, a transjugular intrahepatic access set was used to perform ISF. The hole was secondary enlarged using a cutting or non-compliant balloon. Finally, a kissing stent was performed to the aorto- uni-iliac into a bifurcated endograft.
Abdominal aortic aneurysm (AAA) is a common vascular disease and associated with risk of rupture, but also with a high cardiovascular (CV) event rate. A key difficulty in AAA is predicting these life-threatening complications. Recent studies suggest that the endothelial function of the abdominal aorta might have a correlation with the disease development. A novel, easy to perform, non-invasive test can assess central artery endothelial function (i.e. the carotid artery reactivity (CAR)). The CAR test is based on the cold pressure test (CPT), which induces sympathetic stimulation by placing one hand in cold water. Using duplex ultrasound, central artery blood flow and diameter responses can be examined. Previous work has demonstrated that the CPT is associated with an increase in abdominal aortic diameter, whilst others found that the carotid and coronary artery diameter also shows dilation. Interestingly, a previous study found a strong correlation between carotid and coronary artery diameter responses to the CPT, whilst these artery responses show independent prognostic value for future cardiovascular events in patients with peripheral arterial disease. Possibly, similarity may be present in central artery reactivity to the CPT. To date, no study examined whether carotid and aorta responses are in agreement during the CPT. Given the potential importance of central artery vasoreactivity for AAA, the CAR-test may have potential in this group, especially given the relative simplicity of measuring the carotid artery. The aim of this explorative study is to investigate the correlation between the magnitude of the abdominal aorta and the carotid artery diameter and blood flow responses during the sympathetic stimulation (using the cold pressor test) between healthy young, healthy older and individuals with AAA.
