Filter by:A retrospective cohort study of computed tomography scans of AAA patients considered for repair, in order to identify sex specific differences in abdominal aortic aneurysm (AAA) metrics and the association between anatomical differences/features of complexity and adverse patient outcome.
Thoracic aneurysm is a silent disease with a potential mid-term high risk of death or major complications. Few data are available on the real incidence of major complications in case of small and moderate thoracic aneurysm. Different factors are supposed to increase the risk of aortic enlargement as high blood pressure and sleep disorder breathing. The modality of imaging and clinical follow-up are well defined. In this prospective observational study, the aim to assess the incidence of of major complications during follow-up in a population of patients with a small or moderate thoracic aneurysm. The study will also try to identify systemic factors influencing aneurysm evolution.
To assess the expression of miRNA in patients with TAA, AAA in aneurysmatic tissue and to compare this expression with the healthy tissue in the same patient. In the same cohort, to asses the presence of miRNA in plasma and to compare with the control group. Over the period of three years,to follow subjects in order to assess if the presence of certain miRNAs speeds up or slows down the progression of disease. In patients with intracranial aneurysms to detect miRNA in plasma especially in patients with familial occurrence.
The purpose of this trial is to generate clinical evidence related to key performance outcomes of Endurant II/IIs Stent Graft Systems verses Gore Excluder / Excluder Conformable AAA Endoprosthesis in subjects with Abdominal Aortic Aneurysms. Subjects are randomized and imaging collected at all follow-up time points to assess the primary endpoint.
Background: A sub-study of the AARDVARK (Aortic Aneurysmal Regression of Dilation: Value of ACE-Inhibition on RisK) trial indicated a statistically significant association between central blood pressure (BP) variability and abdominal aortic aneurysm (AAA) growth. The role of anti-hypertensive adherence has not been explored in the context of AAA growth. Objective: To confirm whether higher central BP variability is associated with higher AAA growth rates and to examine the effect of medication adherence on AAA growth rates in a prospective longitudinal cohort study. Methods: Up to 175 patients will be recruited over ten months from two sites with standardised quality control of AAA, BP and antihypertensive non-adherence measurement. Patients (>55 years), with AAAs ≥3cm in diameter (including AAA ≥5.5cm, not proceeding to surgery) will be recruited and undergo AAA ultrasound (US), BP (peripheral and central) and antihypertensive non-adherence measurements every four months (+/- one month) for 24 months. Ambulatory BP variability data will be collected. Data on medication adherence and beliefs around medications will be collected with validated questionnaires. Analysis: Primarily, the relationship between central diastolic BP visit-to-visit variability and AAA growth (estimated by multilevel modelling) based on US measurements and secondarily the relationship between central diastolic BP variability and time taken to reach the threshold for AAA repair (5.5 cm) or rupture.
This is a pilot, prospective, randomized control trial that aim to provide a first estimation of the 3-month post-operative variation in the functional recovery of patients who benefited from an outpatient pre-habilitation program and patients who did not benefit from it.
COIN trial is a a prospective, randomized, placebo-controlled, double-blind, multicenter clinical study. Approximately 230 patients with small abdominal aortic aneurysms (AAA) will be randomly allocated to low-dose colchicine group or placebo group. All study patients will be followed up in the outpatient clinic every 3 months and undergo CTA scans after 24 months from randomization. The primary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA diameter. The secondary objective is to test the hypothesis that low dose colchicine can inhibit the progression of AAA volume, reduce the incidence of clinical outcomes associated with AAA, reduce the incidence of major adverse cardiovascular events and all-cause mortality.
Observational, prospective, cohort study to evaluate, by an opportunistic screening program based on vascular ultrasound, the prevalence and characteristics of Abdominal Aortic Aneurysm (AAA) and Popliteal Artery Aneurysm (PAA) in a female population as well as the prevalence and characteristics of PAA in male population.
Low clopidogrel response has been reported in about 5-44% of the total population, which is associated with an increase in thromboembolism. Recently prasugrel drug widely accepted as a good option for these patients. The purpose of this study is to compare the safety and usefulness of prasugrel versus clopidogrel in patients who are scheduled to undergo stent or diverter treatment for non-ruptured cerebral aneurysms.
The objective of this clinical investigation is to evaluate the safety and technical success of the Basecamp Vascular controllable directional GECKO guidewire when used to facilitate endovascular access to the targeted vessel in order to treat the vascular lesion.
