Summary
Early diagnosis and surgical treatment significantly improve outcomes for patients with subarachnoid hemorrhage (SAH) from ruptured aneurysms. Delayed diagnosis, even with negative CT scans, can negatively impact recovery from this serious neurological condition.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Subarachnoid hemorrhage (SAH) from a ruptured aneurysm is a critical neurological emergency.
- Delayed diagnosis can lead to poorer patient outcomes.
Purpose of the Study:
- To evaluate the outcomes of patients with aneurysmal subarachnoid hemorrhage.
- To specifically assess the impact of delayed diagnosis on patient outcomes.
Main Methods:
- Retrospective study of 94 patients admitted to a tertiary teaching hospital over two years.
- Analysis of patient records focusing on diagnosis, treatment (surgical vs. non-surgical), and outcomes (death, disability, functional recovery).
Main Results:
- Overall mortality was 42.5%, with 15% experiencing disability and 40% achieving functional recovery.
- Surgical treatment resulted in significantly higher functional recovery rates (61%) compared to non-surgical management (6%).
- In cases with delayed diagnosis (15 patients), functional recovery was 47%, with some diagnostic delays attributed to negative CT scans.
Conclusions:
- Early diagnosis and definitive surgical intervention are crucial for improving outcomes in aneurysmal SAH.
- Negative computed tomography (CT) scan results require careful interpretation alongside clinical presentation to avoid diagnostic delays.
