Summary
The modified Cekirge-Saatci classification (mCSC) evolves over time after flow diverter (FD) treatment. Dynamic mCSC risk levels predict aneurysm recanalization, aiding personalized follow-up strategies.
Area of Science:
- Interventional neuroradiology
- Vascular neurosurgery
- Medical imaging analysis
Background:
- Flow diverter (FD) treatment is a key modality for intracranial aneurysms.
- The modified Cekirge-Saatci classification (mCSC) is used to assess aneurysm treatment response.
- Understanding the temporal dynamics of mCSC is crucial for predicting outcomes.
Purpose of the Study:
- To evaluate the temporal evolution of the modified Cekirge-Saatci classification (mCSC) post-flow diverter (FD) treatment.
- To investigate the predictive value of mCSC for aneurysm recanalization.
- To explore an mCSC-based risk stratification approach for patient management.
Main Methods:
- Retrospective analysis of 50 patients with intracranial aneurysms treated with FD.
- Stratification into no-risk, intermediate-risk, and high-risk groups based on mCSC at 4 and 12 months.
- Logistic regression analysis to assess the association between mCSC risk levels and recanalization.
Main Results:
- Recanalization occurred in 28% of cases over a mean follow-up of 104.8 months.
- Both 4-month and 12-month mCSC risk levels significantly correlated with recanalization (p<0.05).
- The 12-month mCSC risk level was an independent predictor of recanalization (OR: 31.031, p=0.015), with dynamic risk transitions observed.
Conclusions:
- The mCSC should be viewed as a dynamic, not static, classification system.
- Longitudinal evaluation of mCSC provides prognostic information for aneurysm recanalization.
- Risk-based interpretation of mCSC can guide individualized follow-up strategies after FD treatment.
