AI for Detection of Brain Aneurysm: Low-cost Opportunistic Screening

The goal of this clinical trial is to verify the opportunistic screening potential of the AI software for detection of brain unruptured intracranial aneurysms (UIA) on routinely performed brain NECT scans in a prospective setting in the Belgian population. The main question the study aims to answer is: Does the AI algorithm has potential to be used as clinical screening potential for detection of brain UIA on brain NECT scans? The performance and the clinical use of the AI algorithm will be measured based on the number of UIA detected by the AI software compared to the number of UIA confirmed by review of a radiologist compared to the number of UIA already known by review of the electronic patient file/additional diagnostic research. Participants will be followed-up following Standard-of-Care (SoC). In addition, participants will be requested to complete a questionnaire (the EQ-5D-5L questionnaire). Furthermore, patient outcomes, complications/death related to the possible (un)ruptured brain aneurysm will be assessed 5 years after study enrolment.

Placental Learning Model for Neurovascular Microsurgery for the Management of Intracranial Aneurysms

Training in microsurgical techniques for the management of intracranial aneurysms is carried out during the practical training of the DES in Neurosurgery and during the continuous training of neurosurgeons according to the indications of the patients of the department. Currently, the recent increase in indications for endovascular treatment compared to surgical indications has led to a decrease in surgical indications and in the experience of neurosurgeons. However, there are still surgical indications that are often complex situations that neurosurgeons must overcome with a specific simulation approach. There are different simulation models for the treatment of intracranial aneurysms. The small animal (rodent) model has the disadvantage of being poorly suited to the reproduction of intracranial aneurysms (different extracranial vessel walls, too small intracerebral vessel caliber) and of being constraining to the establishment. The computerized stimulator model which has the advantage of being able to reproduce the anatomy of a patient but whose haptic sensitivity performance is difficult to reproduce for very fine movements, it is not very accessible because it is expensive. The placental model uses a fresh human placenta, the appearance of the vessels of which is very similar to those found intracerebrally, and dilations on their walls can be performed with a pediatric urinary catheter.

General Anesthesia vs Local Anesthesia for Endovascular Treatment in Patients With Unruptured Intracranial Aneurysm Using Flow Diverter

The prevalence of unruptured intracranial aneurysm (UIA) in the population is about 2%-7%, and once it ruptures and bleeds, the rate of disability and death is extremely high, with 10%-15% of patients dying suddenly before they can seek medical attention, 35% of first-time bleeders, and 60%-80% of second-time bleeders. Survivors are often disabled. Therefore, there is a broad consensus that UIA with surgical indication should be aggressively intervened. The efficacy and safety of flow diverter (FD) in the treatment of UIA has been confirmed by many large clinical trials. Currently, FD placement for UIA is performed under general anesthesia (GA) in most centers, however, some studies have observed that FD placement under local anesthesia (LA) is not as effective as FD placement under general anesthesia and have demonstrated the feasibility of FD placement under local anesthesia (LA) with high technical success rates and low perioperative complication rates and mortality. However, the retrospective design and relatively limited sample size of the above studies may introduce significant bias and affect the confidence of the conclusions. Therefore, the present trial was designed as a randomized controlled trial with the aim of comparing the safety and efficacy of GA and LA in UIA patients undergoing FD placement. The results of this study will help inform future multicenter trials to validate the impact of anesthesia choice on the safety and efficacy in UIA patients undergoing FD placement.

Intravascular Neuro OCT Imaging System for Aneurysm Treatment Evaluation

This is an investigational study for a new medical device called the nOCT (neuro optical coherence tomography) Imaging System, which is manufactured by Spryte Medical, LLC. The nOCT Imaging System takes pictures from inside a blood vessel in your brain. These pictures give your doctor information about the inside of your blood vessel including the disease and any implanted devices. The nOCT Imaging System consists of a probe and a console. The probe is a small, flexible wire-like device designed to navigate through catheters which have already been inserted in your body as part of your planned procedure. Catheters are small, flexible, tubes inserted in your blood vessels which allow your doctor to deliver treatments such as medications, coils, or stents directly to the affected area. The console is a unit that includes a computer, screen and laser light source. The probe is connected to the console. The console provides the probe with low-power light from the laser which is used to scan and create pictures of your blood vessel. The pictures are displayed on the screen of the console for review by your doctor and may be stored for future viewing. The objective of the study is to evaluate the safety and effectiveness of the nOCT Imaging System to provide quality images for diagnostic assessment during endovascular intracranial aneurysm treatment and follow-up.
