Filter by:The goal of this study was to verify the safety and effectiveness of Target Tetra® Detachable Coil in the endovascular embolization treatment of small intracranial aneurysm (≤5mm).
The goal of this clinical trial is to confirm the feasibility and safety of performing radiosurgery on unruptured, low-risk aneurysms in humans. Participants will choose if they want to undergo radiosurgery or not. Participants who choose not to have radiosurgery will be assigned to the observational group. Participants who choose to have radiosurgery performed will be assigned to the radiosurgery group. Participants in both groups will attend an initial exam session as well as four follow-up sessions: Day 0 - Initial questionnaire - CTA scan - MRI - Radiosurgery performed on patients in the radiosurgery group 6 months - CTA scan - Follow-up questionnaire 12 months - CTA scan - MRI - Follow-up questionnaire 24 months - CTA scan - Follow-up questionnaire 36 months - CTA scan - MRI - Follow-up questionnaire Researchers will compare the observational group and the radiosurgery group to see if there is a difference in the incidence of aneurysm rupture during the study period (3 years). The hypothesis is that radiosurgery should not increase the risk of aneurysm rupture.
The aim of this study was toinvestigate the effect of BPB on outcome of upper extremity arteries in patients undergoing interventional embolization of intracranial aneurysms via TRA. A multicenter prospective clinical trial was designed. The study subjects were patients undergoing cerebral aneurysm embolization with TRA. BPB was given in the BPB group patients and no BPB in the control group.The incidence of radial artery spasm (RAS) diagnosed by intraoperative angiography and the occurrence of the unfavorable RA for repeated trans-radial interventions (TRI) diagnosed by vascular ultrasound 1 month after surgery， perioperative changes of blood flow parameters in upper limb vessels,postoperative inflammatory factors and complications were observed in the two groups.
The primary goal of the trial is to investigate whether the experimental arms (receiving the P2Y12 inhibitor Ticagrelor) compared with the control arm (taking dual antiplatelet therapy) could reduce bleeding complications in patients with intracranial aneurysms undergoing Stent-Assisted Coiling.
Plastic particles are a ubiquitous pollutant in the living environment and food chain, so far, plenty of studies have reported the internal exposure of microplastics and nanoplastics in human tissues and enclosed body fluids. Neurosurgery is the only department that can open the skull. In addition to blood and cerebrospinal fluid, there are brain tissue and tumors in the presence of lesions. Whether any of these microplastics and nanoplastics are present remains a mystery. This prospective observational study will harvest biological samples of neurosurgery patients. The objective of this research is to be able to detect microplastics and nanoplastics on blood and operation samples of neurosurgery patients.
This study is a multi-center, prospective, registry study. This research was supported by the National Key Research and Development Program. To establish a domestic multi-center, large-scale "brain-heart comorbidity" dynamic database platform including clinical, sample database, image and other multi-dimensional information requirements, through the construction of a multi-center intelligent scientific research integration platform based on artificial intelligence. Any of newly diagnosed cardiovascular related diseases were identified via ICD-10-CM codes: I21, I22, I24 (Ischaemic heart diseases) [i.e., ACS], I46 (cardiac arrest), I48 (Atrial fibrillation/flutter), I50 (Heart failure), I71 (Aortic disease), I60 (subarachnoid hemorrhage), I61 (intracerebral hemorrhage), I63 (Cerebral infarction), I65 (Occlusion and stenosis of precerebral arteries), I66 (Occlusion and stenosis of cerebral arteries), I67.1 (cerebral aneurysm), I67.5 (moyamoya diseases), Q28.2 (Arteriovenous malformation of cerebral vessels). The data is stored on the brain-heart comorbidity warehouse via a physical server at the institution's data centre or a virtual hosted appliance. The brain-heart comorbidity platform comprises of a series of these appliances connected into a multicenter network. This network can broadcast queries to each appliance. Results are subsequently collected and aggregated. Once the data is sent to the network, it is mapped to a standard and controlled set of clinical terminologies and undergoes a data quality assessment including 'data cleaning' that rejects records which do not meet the brain-heart comorbidity quality standards. The brain-heart comorbidity warehouse performs internal and extensive data quality assessment with every refresh based on conformance, completeness, and plausibility (http://10.100.101.65:30080/login).
This study was designed to identify whether there is a measurable reduction in inflammation in walls of intracranial aneurysms with oral dimethyl fumarate.
This registry study will investigate the incidence of and outcomes associated with clopidogrel hyper-responsive patients treated at Methodist Dallas Medical Center, beginning in January 2018, who suffered cerebral aneurysms.
The goal of this randomized controlled trial is to evaluate the benefits and safety of controlled hypotension in Chinese patients with unruptured intracranial aneurysms(UIA). The main questions it aims to answer are: - To provide high-level evidence of the benefits and safety of controlled hypotension in patients with UIA. - To provide evidence-based medical evidence for blood pressure control of patients with UIA in neurosurgery, and promote the progress of accurate individual management of patients. In this study, the main intervention is enhanced blood pressure lowering in patients with UIA. All Patients will be randomly assigned to either the standard blood pressure lowering (SBPL) group or the enhanced blood pressure lowering (EBPL) group.
The physiopathology of intracranial aneurysm from initiation to ruptured is incompletely understood but included inflammation. The microbiota is known to interact with brain and can promote inflammation. The objective of this study is to describe microbiota with taxonomic and metabolomic analysis. A comparison between ruptured and unruptured intracranial aneurysm will be performed. The study hypothesis is that microbiota is different between ruptured and unruptured patient.
