Safety and Clinical Effectiveness of Pipeline™ Shield Devices for Intracranial Aneurysms

Intracranial AneurysmCerebral Aneurysm6 more

This observational, retrospective, single-arm, multi-centre cohort study will use real-world data (RWD) to develop real-world evidence (RWE) of the safety and clinical effectiveness of the Pipeline™ Flex Embolization Device with Shield Technology™ in Australian patients that have received a flow diversion device to treat an intracranial aneurysm (IA). The medical records from 500 procedures completed at Gold Coast University Hospital in Queensland (QLD), Prince of Wales Hospital in New South Wales (NSW), and Sir Charles Gardiner Hospital in Western Australia (WA), will be analysed. The study will report the risk and likelihood of stroke (ischaemic and haemorrhagic), delayed neurological adverse events and incomplete aneurysm occlusion within sub-groups of the patient cohort and determine the predictive or confounding factors that influence clinical outcomes under pragmatic or 'real-world' conditions.

Role of Circulating MicroRNAs in Pathogenesis of Aneurysms of the Abdominal and Thoracic Aorta -...

Aortic Aneurysm

The objective of this study is to establish whether patients with aortic aneurysm, compared to general population, have higher levels of selected miRNAs and whether there is significant association between the level of miRNA in circulating blood and the size of the aortic aneurysm or the risk of its rupture.

Comparison of Outcomes of Complex Abdominal Aortic Aneurysm Treatment

Juxtarenal Aortic AneurysmPararenal Aneurysm

Background: Open repair remains the gold standard for fit patients with complex AAA. In the past decade, an evolution of devices, design, components, and delivery systems expanded the application of EVAR in these challenging anatomies. Fenestrated stent-grafts are now commercially available for the repair of complex AAA in the United States and Europe. Initial reports have demonstrated a high technical success rate, low renal dysfunction rate, and low morbidity and mortality, with promising short- and long-term results. Other reports have shown excessive morbidity and mortality with fenestrated EVAR (FEVAR). Studies comparing endovascular and open repair are sparse, especially when it concerns long-term outcomes. There are till nowadays only two propensity score-matched studies, one showing worse short-term and another long-term clinical outcome for fenestrated-branched EVAR (F/BEVAR) over open surgical repair (OSR). Aim: The aim of this study will be to compare F/BEVAR versus open AAA repair on short- and long-term clinical outcomes for the treatment of juxta- and pararenal AAA. Methodology: This is a prospective cohort study from the four high-volume AAA repair centers: Belgrade/Serbia, Bologna/Italy, Milan/Italy, Dijklander/Netherland, Amsterdam/Netherland, and Helsinki/Finland. Data will be collected on demographics, baseline comorbidities, AAA parameters (diameter and localization), laboratory values, intra-, and postoperative data. Follow-up examinations (clinical visits and color duplex ultrasonography, CT scans) will be performed 1, 6, and 12 months after the intervention, and annually thereafter. Propensity score analysis will be performed by matching open repair patients to endovascularly treated controlling for demographics and baseline comorbidities. Endpoints: Primary endpoints are all-cause mortality and the freedom from aortic-related reintervention. The secondary endpoint is the 30-day complication rate, especially acute kidney injury according to the RIFLE criteria.

Effective Treatments for Thoracic Aortic Aneurysms (ETTAA Study): A Prospective Cohort Study

Thoracic Aortic Aneurysm

This is a prospective observational cohort study that will collect data from the point of referral through to secondary care, aiming for 3 years median follow-up (range 1-5 years). The data collected will allow estimation of the success of any intervention (in terms of reducing rate of aneurysm growth, rupture or dissection) as well as estimation of the risks associated with the three procedures. Clinical outcomes in the three treatment groups will be described. Aims We aim to answer the following questions: Without procedural intervention for chronic thoracic aortic aneurysm (CTAA), what is the risk of aneurysm growth, dissection, rupture, permanent neurological injury or death? What is the effect on quality of life (QoL)? If a patient has endovascular stent grafting (ESG) or open surgical repair (OSR), what is the risk of growth, dissection, rupture, permanent neurological injury or death? How does QoL change from pre- to post intervention? Can aneurysm or patient related predictors of good/poor treatment outcomes be determined? What is the most cost-effective strategy in: Patients eligible for either ESG or OSR? Patients eligible for either ESG or best medical therapy (BMT)? Patients eligible for either watchful waiting (WW) or intervention (ESG/ OSR)? What further research is required? What would be the most important research to pursue?
