Filter by:Immersion sedation in virtual reality could be an alternative to conventional pharmacological sedation, during interventional cardiology acts on pain and anxiety control. The objective of this study is to determine whether virtual reality immersion is non-inferior to drug sedation on pain and anxiety, during coronary angiography or angioplasty.
The research was planned on a randomized controlled experimental basis. Simple stratified randomization will be performed according to gender and age. Consent will be obtained from children and parents who agree to participate in the research. Before angiography, "Child Fear Scale", "State-Trait Anxiety Scale (STAI-TX)", and "Vital Signs Follow-up Form" will be applied to all children taking part in the study and life signs will be recorded. During angiography, the first group will listen to the music that the child wants to listen to. The second group will listen to the music which determined by the researchers. No music will be played to the control group. During angiography (when the child is listening to the music) vital signs will be recorded in 0. min., 1st minute, 5th minute, 10th minute, 15th minute, 30th minute and 60th minute. "Numerical Pain Scale", "Child Fear Scale", "State Anxiety Scale", and "Vital Signs Follow-up Form" will be re-evaluated to all three groups after angiography.
Revadiab is case-control study aimed to demonstrate that retinal capillary density is altered in patients with type 1 diabetes with glycemic variability compared to those with comparable glycemic control without glycemic variability. An OCT angiography will be used to precisely evaluate retinal capillary density. A secondary objective will be to evaluate if glycemic variability is associated with cognitive dysfunction, using a neuro psychologic evaluation.
The incidence of isolated common iliac artery (CIA) aneurysms is low, but in combination with an abdominal aortic aneurysm (AAA) they are found in approximately 20-40% of cases. Basically, two different endovascular strategies can be applied to treat a CIA aneurysm with, including 1. the coverage and 2. the preservation of blood flow to the internal iliac artery (IIA). Coil and coverage of the IIA is related to ischemic complications, including buttock claudication, erectile dysfunction and the more severe spinal and colonic ischemia. Iliac branched devices (IBD) have been developed to exclude CIA aneurysms preserving the IIA and currently three alternatives are on the market. Clinical results of these devices are promising but loss of patency is not uncommon. The major difference between the two devices is the IIA component. The Cook IBD uses a -non-dedicated IIA component, while in the GORE® EXCLUDER® Iliac Branch Endoprosthesis (Gore IBE device) a dedicated self expanding stent is used. Stresses and forces exerted onto the endograft by aortic pulsatility may have an effect on the durability and functioning of the endograft. Intermittent hinchpoints could also have an effect on stent integrity and stenosis. By evaluating endograft movement during the cardiac cycle (ECG-gated CTA) it is possible to assess the stress and force exerted onto the endograft. This might help gain insight into mechanisms underlying potential endograft failure, and aid procedural planning and the development of future devices with long-term durability. The choice for device is not part of this study.
Optimizing the MRI protocol in acute ischemic stroke remains a challenging issue. In this field, susceptibility-weighted sequences have proved their superiority over T2. Besides the strengthened susceptibility effect, enhanced susceptibility-weighted angiography (eSWAN) sequence provides also a time-of-flight (TOF) effect, allowing the exploration of the intracranial arterial circulation. The objective of this study is to compare eSWAN and 3D TOF, considered as the reference, in the detection of arterial occlusion in acute stroke.
The objective of this study is to evaluate the image quality for different iodine delivery rates at different low voltage scanning protocols (80 or 100 kV ) under the modern advanced Multi-Detector Computed Tomography (MDCT) considering the body weight of patients.
