Study of Complex Intracranial Aneurysm Treatment

Intracranial Aneurysm

The investigator expects that endovascular flow-diversion is superior over revascularization by postoperative modified Rankin scale (mRS) in patients with complex intracranial aneurysms.

Cerebral aneurysm is one of the main diseases that seriously affect human health. The most important treatment method is surgical clipping and endovascular embolization. Not complete occlusion of the aneurysm is a main risk of recurrence and rebleeding after treatment. This study is focused on the 3D model of cerebral aneurysms and preoperative evaluation. Combined with the 3D model, the neurosurgeon can complete the discussion of preoperative prediction of aneurysms and recognize the adjacent bone, blood vessels, aneurysm directions and so on. In addition, the model can also be used to the young doctor's training, and the patient and their families can be convenient and intuitive understanding of the disease, so as to form a good communication between doctors and patients.

Analysis of Selective Cerebrovascular Distribution With FDCT in the Angiosuite

Ischemic StrokeIntracranial Aneurysm3 more

The aim of this study is to evaluate the clinical feasibility of the angiographic Flat Detector CT perfusion imaging (6s PBV) technique. The investigators will examine the specific vessel distribution of patients with steno-occlusive disease, treated with a surgical extracranial-intracranial bypass and assess the cerebral perfusion during test occlusion upon a neurovascular treatment and in intracranial tumor patients referred for potential pre-operative embolization. This study encompasses three scientific objectives: What is the selective contribution of an individual bypass artery to the brain perfusion? Is a selective intra-arterial angiographic perfusion examination useful in the decision-making of performing pre-operative embolization of intracranial tumors? What is the usefulness of performing additive 6s PBV images compared to classical 2D angiography and/or clinical neurological evaluation in case of test occlusion in the evaluation of possible mother vessel occlusion in treatment of complex neurovascular diseases?

Doppler Flow Wires in Cerebral Angiography

AneurysmCerebral Aneurysm

The purpose of this study is to use a wire with a Doppler tip to measure blood flow in vessels in the brain and determine hemodynamic factors associated with treatment success or failure. Many neurological diseases cause abnormal blood flow in the brain in specific vessels. The special wire used in this study is place into brain blood vessels during standard of care procedure to treat such diseases, and blood flow parameters (such as velocity and pressure) are measured to gain better understanding of these neurological diseases.

Impact of Genetic Polymorphism on Propofol Requirement and Recovery for Total Intravenous Anesthesia...

Unruptured Cerebral Aneurysm

In neurosurgical anesthesia, propofol based total intravenous anesthesia (TIVA) is frequently used due to brain relaxation and less effect on electrophysiologic monitoring. Response to propofol can vary between individuals and be associated with clinical factors including age and weight, and genetic polymorphism. Because the importance of rapid recovery in neurosurgery with long operation time is emphasized recently, the choice and dose adjustment of anesthetics should be determined according to clinical and genetic factors. Recently, researches about genetic variations have been performed with single nucleotide polymorphism (SNP). The aim of this study is to determine SNPs associated with propofol recovery and response in Korean adult population undergoing propofol based TIVA for clipping of unruptured cerebral aneurysm.

Virtual Simulation for Woven EndoBridge Device Sizing

AneurysmIntracranial Aneurysm

Selection of the appropriate size of the device is mandatory during aneurysm treatment with a WEB. The Investigators aimed to investigate if virtual simulation with Sim&Size software may have an impact on technical, angiographic, and clinical outcomes after WEB treatment. Data from two large-volume centers were collected and compared (January 2017-January 2020). Virtual simulation was systematically adopted in one center, while conventional sizing was used in the other one. Outcomes were the duration of intervention, the radiation dose (mGy), the number of corrective interventions for inappropriate WEB size, the number of WEBs not deployed, angiographic occlusion, and complications. Univariate and multivariate linear models were adopted.
