@neurIST : Intregrated Biomedical Informatics for the Management of Cerebral Aneurysms

Intracranial Aneurysm

The primary aim of the SwissNeuroFoundation AneurysmDataBase Project is to implement information technology based tools to create and use a holistic reference database specific to intracranial aneurysms (IA). The SwissNeuroFoundation AneurysmDataBase are concerned with generating the data with which to populate this database. The purpose for populating the database are to: Screen for and evaluate markers of risk for intracranial aneurysm formation and aneurysm rupture. Are considered as markers the following: genetics factors, microbiota, environmental factors, congenital factors (ie: cerebrovascular anatomical variants), transcriptomics signature, proteomics signature,shape characteristics, haemodynamics characteristics. Screen for and evaluate prognostic factors of outcome regarding different management strategies including watchful observation, microsurgical treatment, endovascular treatment or any combination thereof. Implement and evaluate patient-specific management protocols integrating all available information. Evaluate the impact of the database and use of tools to improve care, reduce costs, support knowledge discovery and promote new industrial developments.

Intracranial Aneurysm

the goal of this clinical trail is to evaluate the efficiency and safety of intracranial aneurysm assistive software in the preoperative assessment. The trail is designed as retrospective, multicenter, controlled clinical trail. Collecting probable cases images retrospectively according to inclusion criteria and exclusion criteria strictly. Controlling bias strictly, to make sure the efficiency and safety of intracranial aneurysm assistive software is evaluated reliably and precisely. In our trail, software-assisstant planning controls against experienced-surgeon-independent planning,which aims to avoid bias effictively and eliminate non-test interferences.

Prospective, Multicenter Cohort Study on the Safety and Efficacy of Treatment for Middle Cerebral...

Middle Cerebral Artery Aneurysm

Intracranial aneurysm is one of the most common cerebrovascular diseases, with a prevalence of about 3.2%. With the aging of the population and the further popularization of MRA and other examination methods, the prevalence of intracranial aneurysm will further increase. Rupture of intracranial aneurysm is an important cause of death and severe disability in patients. The annual rate of rupture of intracranial aneurysm is about 1%, and the size of aneurysm, the location of aneurysm in the posterior circulation, and the history of subarachnoid hemorrhage on the aneurysm wall are the risk factors for aneurysm rupture. Phases are currently recognized tools for assessing the risk of aneurysm rupture, which can provide important guidance for neurosurgeons and patients to decide whether to actively intervene. In the last century, for patients with intracranial aneurysm with high risk of rupture, craniotomy and clipping for intracranial aneurysm was the gold standard for treatment. However, with the rapid development of embolization technology and materials in the past 20 years, the application of endovascular embolization for intracranial aneurysms has been more and more widely, especially after several large prospective studies such as ISAT and ISUIA, endovascular embolization has more advantages over craniotomy clipping.Whereas, it is still very popular to adopt craniotomy clipping for middle cerebral artery aneurysms, the main reasons for which are relative superficial location, wider aneurysm neck, smaller parent artery and more branching vessels, etc., which make early endovascular embolization treatment not advantageous. With the maturity of stent-assisted embolization technology in recent years, the use of a new generation of stents, and the improvement of perioperative anti-platelet strategies, endovascular embolization has achieved good results in the treatment of middle artery aneurysms. However, these studies were retrospective, single-center studies, subject to a variety of confounding factors, and the reliability of the results is limited. Therefore, it will be of great clinical significance to carry out a prospective, multi-center clinical study on the treatment strategy of middle cerebral artery aneurysms. Patients with unruptured middle cerebral artery aneurysms who had been diagnosed with at least one imaging (CTA/MRA/DSA)were enrolled. The treatment including endovascular embolization and craniotomy clipping was determined according to routine management in the center. After receiving informed consent from the patients, the safety and effectiveness data were obtained to verify whether endovascular embolization was safe and effective. Through further follow-up and data analysis, protective factors and risk factors for the treatment of middle cerebral artery aneurysms were investigated. Through well-designed clinical studies, safer and more effective treatment methods can be found, and potential factors leading to perioperative complications can be found, ultimately improving the prognosis of patients with middle cerebral artery aneurysms.

Prediction of Outcomes After Surgery for Unruptured Intracranial Aneurysms

AneurysmBrain

Accurate preoperative identification of patients at high risk for adverse outcomes would be clinically advantageous, as it would allow enhanced resource preparation, better surgical decision-making, enhanced patient education and informed consent, and potentially even modification of certain modifiable risk factors. The aim of the Prediction of adverse events after microsurgery for intracranial unruptured aneurysms (PRAEMIUM) study is therefore to develop and externally validate a clinically applicable, robust ML-based prediction tool based on multicenter data from a range of international centers.

Stroke Thrombectomy and Aneurysm Registry

StrokeThromboses3 more

This international multi-center registry is used to collect existing information and outcomes for patients undergoing an operation for treatment of injuries to the brain including the blockage of blood flow to an area of the brain, an abnormal ballooning of an artery, abnormal tangling of blood vessels, abnormal formation of blood vessels, tearing of vein, and bleeding in the brain. This information is used to help predict outcomes that undergo an operation for treatment of the above-listed brain injuries. Additionally, the information is used to compare techniques and devices' effects on technical and clinical outcomes.

Microsurgical Clipping and Endovascular Embolization Comparative Prospective Randomized Trial

Ruptured Cerebral AneurysmUnruptured Cerebral Aneurysm

Despite the active development of surgical methods of treatment (endovascular embolization and microsurgical clipping) of cerebral aneurysms, determining the indications and method of surgical treatment of cerebral aneurysms still causes debate in many cases. To a greater extent, this concerns the treatment of unruptured aneurysms. While there are a number of randomized trials of surgical treatment of ruptured cerebral aneurysms, there is currently no published randomized trial comparing surgical clipping and endovascular embolization of unruptured aneurysms. The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular embolization of cerebral aneurysms (both ruptured and unruptured) in a prospective, randomized fashion.

Multidimensional Evaluation of Patients With Ruptured or Unruptured Cerebral Aneurysm Undergoing...

Cerebral Aneurysm

Cerebral aneurysms are common changes in intracranial angioarchitecture. Unruptured aneurysms are increasingly identified thanks to the imaging techniques used in daily clinical practice. Since bleeding remains a highly dramatic event burdened by significant morbidity-mortality (about 50%), endovascular therapy, in combination with classic surgical therapy, is an essential element in contemporary medicine. Endovascular and surgical treatment represent the standard of care. The rationale of this study is to identify clinical and radiological characteristics, mainly neuro-radiological ones, not fully explored in previous studies, which can help predict the outcome of patients affected by cerebral aneurysm. The study will have the characteristics of a retrospective study on patients with cerebral aneurysm treated at our center from 1 January 2015 to 31 December 2023. Objective of the study is the multidimensional evaluation in patients with cerebral aneurysms, ruptured and unruptured, undergoing an endovascular embolization procedure or surgical treatment.
