Summary
Artificial intelligence (AI) provides real-time alerts during cerebral aneurysm coiling, enhancing safety and accuracy. This preliminary study shows AI assistance is effective and safe for neuroendovascular procedures.
Area of Science:
- Neurosurgery
- Medical Technology
- Artificial Intelligence
Background:
- Neuroendovascular procedures demand constant monitoring of multiple devices and screens.
- Overlooking unintended device movements can lead to serious complications.
- Artificial intelligence (AI) offers real-time notifications for device movements during procedures.
Purpose of the Study:
- To report the preliminary experience of using real-time AI-assisted cerebral aneurysm coiling in humans.
- To evaluate the efficacy, accuracy, and safety of AI-driven notifications during neuroendovascular procedures.
Main Methods:
- A real-time AI-assistance software was utilized during coil embolization for nine unruptured cerebral aneurysms.
- The AI system provided notifications for 'coil marker approaching', 'guidewire movement', and 'device entry' on biplane fluoroscopic images.
- Efficacy, accuracy, and safety were assessed via video recording analysis.
Main Results:
- The AI system performed correctly in all procedures.
- High precision (92.7%) and recall (97.2%) were achieved.
- AI notifications led to guidewire adjustments in 19% of true positive cases, demonstrating potential effectiveness without adverse events.
Conclusions:
- The AI software demonstrated sufficient accuracy and safety in this initial human study.
- This represents the first reported use of real-time AI for cerebral aneurysm coiling assistance.
- Further large-scale studies are needed to confirm effectiveness, but AI shows significant promise for neuroendovascular therapy.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
