Navigation Support With Mixed Reality With CORTEXPLORER MED
Cranial AneurysmDuring the last 15 years, neuronavigation has become an essential neurosurgical tool for pursuing minimal invasiveness and safety. One drawback of such devices is the fact, that the neurosurgeon has to look away from the surgical field onto a dedicated workstation screen. Additionally, the operator is required to transfer this information from the "virtual" environment of the navigation system to the real surgical field - whereas the real patient may be fixated and positioned differently compared to the visualization on the screen. Mixed-reality may have the potential to support this, by merging data from the real environment with virtual information and vice-versa. In the context of surgical navigation, the main goal of mixed reality systems is to provide a real-time updated 3D virtual model of anatomical details, overlaid on the real surgical field. In this sense, the mixed reality is the process of enrichment of reality with additional virtual contents. This clinical investigation aims at the collecting of clinical data about the mixed-reality supported planning, the registration accuracy and overall precision of the navigation system and the clinical outcome.
Effect of Remote Ischemic Preconditioning on the Incidence of Contrast Induced Nephropathy in Patients...
Aortic AneurysmIschemic PreconditioningIntroduction: Contrast induced nephropathy (CIN) is a major inconvenience in the use of iodinated contrast media (ICM) and it is associated with a significant increase in morbimortality and cost of hospitalization. Remote ischemic preconditioning (RIPC) is a non-invasive and cost-effective tissular protection technique that has proven beneficial in decreasing renal insult in patients receiving intravascular contrast. Aim: The primary outcome of this study is to evaluate the impact of RIPC on the incidence of CIN in patients undergoing endovascular aneurysm repair.Material and Methods: Patients suffering from aortic aneurysm were recruited prior to the administration of iodinated contrast media. Randomization was used to assign patients into the control/RIPC groups. Biochemical parameters determined renal function before and after surgery in immediate (24-72 hours) and at 30 days' follow-up.
Role of Propofol Postconditioning on Oxidative Stress and Cognitive Function
Cerebral Arterial AneurysmThe purpose of this study was to evaluate differences between propofol postconditioning and sevoflurane anesthesia in the intracranial aneurysm surgery about antioxidant effect.
Hydrogel Balloon Assisted Intracranial Aneurysm Coiling Registry
Intracranial AneurysmsAneurysm1 moreThe objective of the GELATIN registry is to prospectively evaluate intracranial aneurysm occlusion and retreatment rates as well as adverse event rates in patients undergoing balloon-assisted coiling using the MicroVention Scepter Occlusion Balloon Catheter and second-generation MicroVention hydrogel coils for treatment of previously treated or untreated ruptured and unruptured intracranial aneurysms.
Safety and Performance of the Penumbra Liberty Stent in the Treatment of Wide-Neck, Saccular, Intracranial...
Wide Neck Intracranial AneurysmsThe 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.
Image Quality and Radiation Dose in Angiography
Arteriovenous MalformationsAneurysm2 moreClarityIQ is a novel X-ray imaging technology, that combines advanced real-time image noise reduction algorithms, with state-of-the-art hardware to reduce patient entrance dose significantly. This is realized by anatomy-specific optimization of the full acquisition chain (grid switch, beam filtering, pulse width, spot size, detector and image processing engine) for every clinical task individually. Furthermore, smaller focal spot sizes and shorter pulses are used, which are known to positively influence image quality . The final effect on the clinical image quality is investigated in this study.
A Clinical Study to Evaluate the Safety and Performance of the Modular AAA Stent-Graft System
Cardiovascular DiseasesAbdominal Aortic AneurysmThis is a prospective multicenter observational study with 20 patients to evaluate the performance of SCITECH stent for treatment of AAA. Will be enrolled the patient demographics, laboratory tests, medical history, clinical evaluation, physical examination, adverse events. The benefits and risks of the study should be explained before any specific test or procedure of the study. The written consent must be obtained from the patient. No action specifies the study should be performed while the patient has not signed the form of consent.
Safety and Efficacy Study of a Single Dose of NA-1 in Patients Undergoing Endovascular Repair of...
Subarachnoid HemorrhageRuptured Intracranial AneurysmThis is a randomized, double-blind, placebo-controlled, single-dose study investigating the safety and efficacy of NA-1 in patients with subarachnoid hemorrhage (SAH) undergoing endovascular repair of ruptured intracranial aneurysms. Up to 300 male and female patients with SAH undergoing endovascular repair of a ruptured intracranial aneurysm will be dosed with 2.60 mg/kg of NA-1 or placebo as a 10 minute intravenous infusion after completion of the endovascular procedure on Day 1 of the study period. Subjects will undergo interim procedures at Day 2-4, Day 30-45, and end-of-study procedures on Day 90.
