In this study, the effect of a decision aid regarding the choice between watchful waiting or surgical treatment of AAA is explored, regarding decisional conflict, knowledge, satisfaction, quality of life, anxiety and clinical endpoints.
1) To unravel the pathogenesis of DCI by studying the time course of cerebral perfusion and vasospasm in patients with aneurysmal SAH with CT, and 2) to obtain a diagnostic tool for the detection of DCI on the basis of CT-perfusion (CTP) parameters…
- To assess the number of de novo aneurysms in patients who underwent therapeutic ICA occlusion more than 5years ago.- To assess infarct load in patients who underwent therapeutic ICA occlusion more than 5 years ago.- To evaluate the distribution of…
To assess the safety and performance of Aorfix* Stent Graft in the treatment of Abdominal Aortic and Aorto-Iliac Aneurysm where a significant degree of vessel angulation exists at the neck of the aneurysm or in the common iliac arteries.
The objective of the current study is to determine whether the wait-and-see policy affects anxiety levels and quality of life in patients with aortic abdominal aneurysms between 3 and 5.5 cm in diameter. Furthermore, we aim to examine the influence…
To assess the influence of bloodpressure, wall thickness, wall properties, and geometry changes throughout the cardiac cycle on the wall stress calculations. Previous analysis were performed with an assumed bloodpressure value, an uniform wall…
Prospectively compare the sensitivity of 2D DSA and 3D rotational angiography in the detection of intracranial aneurysms.
I. The main objective of our study is to differentiate between patients with stable or slowly growing AAA from patients with rapidly growing AAA. We believe that inflammation is a major player in the process of growth. In order to achieve our main…
Correlation of FDG uptake and in vitro aneurysm wall tensile strength. (primary objective). The effect of aneurysm sac depressurisation, after endovascular aneurysm repair, on aneurysm wall inflammation (secondary objective).
In the presented study we would like to investigate the genetic background of the AAA with a twofould objective, namely the possibility of presymptomatic diagnosis of the AAA and the definition of molecular mechanism as possible therapeutic targets.
To establish an operational reference database on intracranial aneurysms encompassing clinical and genetic data on at least 800 patients, 400 controls and 400 relatives of patients where a familial trait is recognized, together with imaging data on…
The primary research question is:-What is the influence of cognitive functioning on on the quality of life after SAH on the long term?Two secundary research questions are:-Is there a specific neuropsychological profile after SAH on the long term?-…
To test whether 100 mg doxycycline inhibits aneurysm growth
1. The application of 4D flow MR imaging to analyse blood flow patterns (flow angle, flow asymmetry), regional vessel wall parameters (regional wall shear stress, vessel wall thickness) and pulsed-wave velocity in neoaortic root, carotid artery and…
1. To assess the prevalence of gadolinium-enhancement of the aneurysm wall in patients with unruptured aneurysms2. To assess the relation between gadolinium-enhancement of the aneurysm wall and a. The use of anti-inflammatory drugs (including…
to quantitatively characterize the stresses and forces on an implanted endograft during the cardiac cycle in terms of longitudinal movement.
Primary objective: -To determine the accuracy of sCTA compared to DSA in the visualisation of the degree of occlusion in the FU of intracranial aneurysms treated with Surpass. Secondary objectives:-To determine the accuracy of sCTA compared to DSA…
Primary objective: - To determine the accuracy of sCTA compared to DSA in the visualisation of the degree of occlusion in the FU of intracranial aneurysms treated with Surpass. Secondary objectives:-To determine the accuracy of sCTA compared to DSA…
The primary objective of this study is to observe if there are differences in diameter measurements of 3T MRI and CTA at baseline and 1 year after baseline measured by two independent observers (radiologist) blinded for previous imaging. The…
The main goal of this pilot study is to analyze if using the 7.0 Tesla MRI scanner potential markers predicting aneurysmal rupture (i.e thickness and enhancement of the aneurysmal wall) can be studied in IA patients.
