Follow-Up Results of Partially Thrombosed Intracranial Aneurysms with Cross-Sectional Imaging: The Case for Introducing a New Grading System

Key Points

• The aim is to assess a new grading system for partially thrombosed intracranial aneurysms and its clinical relevance.
• Utilized cross-sectional imaging (CSI) for categorizing cases.
• Developed a three-group categorization system based on imaging results.
• Compared the new classification against conventional angiographic assessments.
• The new grading system provides a more meaningful assessment of size changes in thrombosed masses.
• It correlates better with functional outcomes compared to traditional classifications.
• Improved categorization may lead to better clinical decision-making.
