Summary
This study developed a stable biomathematical model using binary logistic regression to predict aneurysm rupture risk. The model accurately identifies aneurysm status using biomorphometric data, aiding clinical decision-making.
Area of Science:
- Biomathematics and Medical Imaging
- Cerebrovascular Research
- Computational Fluid Dynamics
Background:
- Biomathematical models offer insights into aneurysm growth and rupture mechanisms.
- Regression models can identify key parameters influencing aneurysm rupture.
- A modified binary logistic regression model was developed and validated.
Observation:
- CT angiography and 3D reconstructions were used to obtain aneurysm dimensions.
- Forward stepwise binary logistic regression was applied to a cohort of 279 aneurysms.
- Key dimensions and aspect ratio were significantly larger in ruptured aneurysms (p < 0.01).
Findings:
- Aneurysm volume and location correlated with rupture risk.
- The validated model demonstrated 83% sensitivity and 80% accuracy in predicting aneurysm status.
- Biomorphometric data proved valuable in determining aneurysm status.
Implications:
- This validated model can accurately predict aneurysm rupture probability.
- The findings support the use of biomorphometric data in clinical assessments.
- This approach may enhance the management of patients with aneurysms.
