Filter by:Magnetic resonance elastography is a novel non-invasive MRI technique to obtain stiffness of soft tissues such as liver, heart, kidneys, etc. In this imaging technique a person is laid in an MR scanner and a paddle (plastic drum) is put on the area of interest to send sound vibration via a speaker placed outside the scan room which is connecting plastic drum via a plastic tube. These vibrations are scanned using MRI to estimate the stiffness of soft tissues such as liver, heart, kidneys, breast etc.
Evaluation of the Multilayer Flow Modulator (MFM) for Endovascular Thoracoabdominal Aneurysm Repair. The objectives of the study is to determine the efficacy, safety and performance of the MFM and its delivery system in patients at high surgical risk presenting with a type II, III thoracoabdominal aneurysm, below the left subclavian and above the iliac bifurcation, according to the Crawford classification.
The primary aim of this study is to determine if doxycycline (100 mg bid) will inhibit (by at least 40%) the increase in greatest transverse diameter of small abdominal aortic aneurysms (3.5-5.0 cm in men, 3.5-4.5 cm in women) over a 24-month period of observation in comparison to a placebo-treated control group.
This study is a prospective, multi-center registry of patients with intracranial aneurysms who are treated by the PC 400 System. Data for each patient are collected up to 12 ± 3 months post-procedure for the study.
The purpose of this study is to assess the safety and performance of the Penumbra Liberty Stent System as adjunctive treatment to embolic coils for wide-neck, saccular, intracranial aneurysms.
The aorta is the main blood vessel that comes out of the heart and distributes blood to the whole body. In some people, the aorta becomes swollen (aneurysm) and bursts, especially as it passes through the abdomen. These 'abdominal aortic aneurysms' often occur without symptoms and can burst or rupture without warning. This usually leads to death and represents the thirteenth commonest cause of death in the United Kingdom. In this study, we are looking at a new technique that can look at the aortic aneurysm using magnetic resonance imaging; a technique that does not require x-rays or radiation. We have recently shown that, using magnetic resonance combined with a new imaging agent USPIO, we can detect 'hotspots' of activity in these aneurysms that seem to predict which aneurysms grow rapidly, and are therefore potentially at risk of rupture. We here propose to conduct a study in Edinburgh that will invite all patients who are under surveillance because of an aneurysm. We will image these patients using this novel technique and see if we can identify which patients burst their aneurysm, have an aneurysm that grows so large it needs to have surgery, or die. This will be important to establish as it will potentially lead to a new way of managing people that could ultimately save lives. This is particularly timely as national screening and surveillance programmes are currently being launched.
The purpose of this prospective registry is to collect real world, post-marketing data on the use of Stryker Target® 360,Target® 2D, and 2nd generation Target® Nano coils for the embolization of ruptured or unruptured intracranial saccular aneurysms. Up to 300 patients (150 in the TARGET 360°/Helical arm and 150 in the New NANO arm) presenting with intracranial aneurysms suitable for coil embolization will be enrolled at up to 20 sites. A post hoc analysis comparing Target® 360° and Target® 2D coil technical and clinical endpoints will be performed.
The purpose of this observational Post-Market Surveillance Registry is to gather post-market data on the performance of the CE marked Vascutek Anaconda™ Stent Graft System for the repair of Abdominal Aortic Aneurysms (AAA). The Study population consists of patients suitable for endovascular repair of AAA. Patients will be followed at 1, 3, 6, 12, 18, 24, 36, 48 and 60 months post-implantation.
The purpose of the Zenith® p-Branch® OTS Multicenter Study is to provide an early clinical experience and evaluate the safety and effectiveness of the Zenith® p-Branch® in the treatment of pararenal or juxtarenal abdominal aortic aneurysms (AAA).
The objective of this study is to assess the safety and effectiveness of the Endologix Nellix® System for the endovascular repair of infrarenal abdominal aortic aneurysms (AAA).
