Summary
Surgery outcomes for 703 aneurysmal subarachnoid hemorrhage patients were analyzed. Clinical grade and aneurysm location significantly impacted outcomes, suggesting a risk score approach could optimize surgical timing.
Area of Science:
- Neurosurgery
- Neurology
- Medical Statistics
Background:
- Aneurysmal subarachnoid hemorrhage (aSAH) is a critical condition requiring timely surgical intervention.
- Predicting surgical outcomes in aSAH patients is crucial for effective management.
Purpose of the Study:
- To analyze factors influencing surgical outcomes in 703 patients with aSAH.
- To evaluate the utility of a risk score estimation approach for optimizing surgical timing.
Main Methods:
- Retrospective analysis of 703 patients undergoing surgery for aSAH.
- Evaluation of patient data including age, medical conditions, vasospasm, clinical grade (Hunt and Hess), and aneurysm location.
- Development of a risk score based on adverse factors to determine optimal surgical timing.
Main Results:
- Favorable outcomes were high for Hunt and Hess grades I-III (90-96%) but lower for grade IV (58%).
- Older age (>60) and vertebrobasilar aneurysms were associated with poorer outcomes.
- Associated medical conditions and anterior circulation aneurysms showed better outcomes compared to vertebrobasilar.
- Angiographic vasospasm alone did not significantly influence outcomes.
Conclusions:
- Clinical grade, age, and aneurysm location are key predictors of surgical outcomes in aSAH.
- A risk score estimation approach can potentially improve patient management and optimize surgical timing for ruptured intracranial aneurysms.
