Flow-diverting Devices for the Treatment of Middle Cerebral Artery Bifurcation Aneurysms

The goal of this clinical trial is to learn if flow diverter (FD) offers advantages over conventional stent-assisted coiling in the treatment of middle cerebral artery (MCA) bifurcation aneurysms . It will also learn about the safety of flow diverter (FD) treatment. The main questions it aims to answer are: Does flow diverter (FD) treatment improves the rate of complete aneurysm occlusion and patients' neurological function? Does flow diverter (FD) treatment loweres the probability of aneurysm recurrence and the occurrence of complications? Researchers will compare FD to a conventional stent-assisted coiling to see if FD treatment works better to treat MCA bifurcation aneurysms. Participants will: Undergo stent-assisted coiling or flow diverter treatment Take pre-operative and pre-discharge head MRI scans, neurological function assessments, and cognitive function assessments Visit the clinic 1 year for checkups and tests

Efficacy and Safety of Methylprednisolone After Flow-Diverter Stent Implantation in Unruptured Intracranial Aneurysms

Study Title: Testing Methylprednisolone to Prevent Strokes After a Stent Procedure for Brain Aneurysms What is the purpose of this study? This study aims to find out if a short course of a steroid medicine called methylprednisolone can help prevent strokes and other brain-related complications in patients who have a "flow diverter" stent placed to treat an unruptured brain aneurysm. The main goal is to see if this treatment reduces the combined number of new strokes (both clot-related and bleeding-related) or brain injury-related deaths within the first 30 days after the procedure. Who can participate? Adults aged 18 or older with an unruptured brain aneurysm (size 3-25mm) who are scheduled to receive a flow-diverting stent and can provide informed consent may be eligible. Key reasons someone might not be able to join include: having multiple aneurysms needing quick treatment, being pregnant or breastfeeding, having a history of recent stroke, having active infections or stomach ulcers, having severe kidney disease, having very high/uncontrolled blood pressure or blood sugar, or already being on long-term steroid therapy. What will happen in the study? This is a multicenter, randomized, double-blind study. This means: Participants will be randomly assigned (like flipping a coin) to one of two groups. One group will receive methylprednisolone. The other group will receive a placebo (an inactive substance that looks identical). Neither the participants nor their doctors will know which treatment is being given. All participants will receive the standard care for the stent procedure and aftercare. How long will the study last? The treatment period is short (around the time of the procedure). Participants will be closely monitored in the hospital and will have a follow-up visit around 30 days after the procedure to check their health status. What will be measured? The researchers will mainly track whether participants have any stroke or brain injury-related death in the first 30 days. They will also check for other complications like bleeding, infections, and changes in daily function and quality of life. Safety will be monitored throughout. How many people will take part? The study plans to enroll approximately 864 participants across multiple hospitals. Study Dates: The study is expected to start enrolling patients in January 2026 and finish in August 2027. Who is organizing the study? This study is sponsored and led by Zhujiang Hospital, Southern Medical University.

Safety and Efficacy of Silk Vista and Silk Vista Baby Flow Diverter for Intracranial Aneurysm Treatment

The FIRST study is an observational, prospective, multi-center, international, single-arm, study. The aim of the study is to collect safety and efficacy information on the use of the silk vista and silk vista baby flow diverter in order to assess clinical safety and performance of the device for treating intracranial aneurysms. All patients with intracranial aneurysm ruptured or unruptured, whatever the localization of the aneurysm, and treated with silk vista or silk vista baby, will be consecutively enrolled in the study. The patient's inclusion and follow up in the study will occur as part of their usual standard of care.
