Active clinical trials for "Intracranial Aneurysm"

The purpose of the Pipeline™ Flex Embolization Device with Shield Technology™ Post Approval Study (PAS) ("Pipeline™ Shield PAS") is to collect on-label use data in patients undergoing treatment for intracranial aneurysms (IA) using the Pipeline™ Flex Embolization Device with Shield Technology™ ("Pipeline™ Shield Device") in a real-world post approval setting within the United States.

Intracranial aneurysm is the main cause of subarachnoid hemorrhage, and the incidence of subarachnoid hemorrhage in Chinese population is about 5%. The intervention of unruptured intracranial aneurysms is controversial because of its great harm after natural rupture and bleeding, and about a quarter of patients still have poor prognosis through existing invasive treatment methods. How to accurately determine the instability risk of unruptured intracranial aneurysms is the key to resolve this controversy. In previous studies, the stability of intracranial aneurysms involves many characteristics, and the sample size is small. Most of them are retrospective studies and studies on the status after change (rupture/growth). Therefore, the relevant risk factors are not clear at present, and there is still a lack of reliable prediction model. Based on the above facts, this study proposed based on the national hundred regional medical institutions set up the network registration platform of unruptured intracranial aneurysms, real time and openness of Internet, through the way of case resource sharing build unruptured intracranial aneurysm queue, collecting clinical characteristics, imaging features, hemodynamic detection of biological samples and the results of the analysis data, And observe them for two years. The artificial intelligence platform of Tonglian Medical Health was used to integrate and analyze and learn all the data, and then the risk factors related to the stability of intracranial aneurysms within two years were obtained, and the stability prediction model of unruptured intracranial aneurysms was constructed. This study will build the largest network registration platform and population follow-up cohort of unruptured intracranial aneurysms in China, and put forward a prediction model for the stability of unruptured intracranial aneurysms by integrating the multi-dimensional factors of intracranial aneurysms, so as to provide a powerful auxiliary judgment tool for the clinical decision-making of this disease.

The protocol has many assets. A prospective nationwide recruitment allows for the inclusion of a large cohort of patients with UIA. It will combine accurate clinical phenotyping and comprehensive imaging with CAWE screening. Besides, it will enable to exploit metadata and to explore new pathophysiological pathways of interest by crossing clinical, genetic, biological, and imaging information.

This study is intended to show that the application of the Accero® (heal) stent is safe within the given indication.

The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage

Patients who will undergo a intracranial aneurysm (IA) surgery are educated concerning their disease and the surgical procedure.The objective of this study is to explore the advantages of conventional, virtual reality and 3D stereolithographic models for patient and resident education in the treatment of lAs.

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.

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).

The purpose of this research study is to evaluate the ability of laser speckle contrast imaging to visualize blood flow in real time during neurosurgery. Real-time blood flow visualization during surgery could help neurosurgeons better understand the consequences of vascular occlusion events during surgery, recognize potential adverse complications, and thus prompt timely intervention to reduce the risk of stroke. The current standard for visualizing cerebral blood flow during surgery is indocyanine green angiography (ICGA), which involves administering a bolus of fluorescent dye intravenously and imaging the wash-in of the dye to determine which vessels are perfused. Unfortunately, ICGA can only be used a few times during a surgery due to the need to inject a fluorescent dye, and provides only an instantaneous view of perfusion rather than a continuous view. Laser speckle contrast imaging does not require any dyes or tissue contact and has the potential to provide complementary information to ICGA. In this study we plant to collect blood flow images with laser speckle contrast imaging and to compare the images with ICGA that is performed as part of routine care during neurovascular surgical procedures such as aneurysm clipping.

To conduct a retrospective multicenter cohort study to define benchmark values for best achievable outcomes following microsurgical clipping of unruptured intracranial aneurysms (UIA).
