Longitudinal study to pulsatility and expansion in aortic stent grafts

Information on the dynamics and shape of the device and how these change over time will improve our understanding about the fixation of the device, which may help in stent selection and in designing stent grafts that are more durable.

Clinical relevance of Positron Emission Tomography (PET) imaging following endovascular aneurysm repair using the Nellix endoprosthesis.

To determine FDG uptake following uncomplicated EVAR using the Nellix endoprosthesis. Does uncomplicated EVAR using the Nellix endoprosthesis result in increased FDG uptake and false positive PET imaging? .

Pilot study Clip design
A pilot study about the first use of the Elana Clip design to create intracranial anastomoses

The objective of this pilot study is to investigate the feasibility of using the Clip system in a human setting in creating an intracranial arteriotomy in a non-occlusive, sutureless fashion. Although the focus is on the technical success of the…

Nerve-sparing aorto-iliac reconstruction surgery; functional outcome and clinical feasibility.

1 Assessment whether using a nerve-sparing exposure of the aortoiliac tract during vascular reconstruction will lead to a neurophysiologically intact sympathetic pathway to the intra-pelvic organs and thus to an intact postoperative function.2…

Silent MRA of intracranial arteries: follow-up of aneurysms treated with coils

Test the optimized MRI sequences/technology against commercially-available, clinical MRIsequences in terms of image quality, signal-to-noise ratio (SNR), contrast-to-noise ratio(CNR), speed, and accuracy/reproducibility of extracted quantitative…
