Summary
Advances in subarachnoid hemorrhage (SAH) management include rapid CT diagnosis and critical care. Endovascular coiling is increasingly favored over surgery for ruptured aneurysms, though long-term outcomes require further study.
Area of Science:
- Neurology
- Radiology
- Interventional Radiology
Background:
- Subarachnoid hemorrhage (SAH) management has seen significant advancements.
- Prompt diagnosis and critical care are essential for patient outcomes.
- Ruptured aneurysms pose a high risk of re-bleeding, mortality, and morbidity.
Purpose of the Study:
- To review current diagnostic imaging modalities for SAH.
- To emphasize the role of radiology in diagnosing and managing aneurysmal SAH.
- To provide an evidence-based approach to imaging and interventional radiology in SAH.
Main Methods:
- Review of current diagnostic approaches for SAH.
- Emphasis on aneurysmal SAH and radiological perspectives.
- Evidence-based analysis of imaging and interventional radiology's role.
Main Results:
- High-resolution CT and critical care are key to SAH management.
- CT angiography is emerging as a rapid, minimally invasive alternative to digital subtraction angiography (DSA).
- Endovascular coiling, particularly with Guglielmi detachable coils, is revolutionizing ruptured aneurysm treatment, shifting from surgical clipping.
Conclusions:
- Interventional radiology techniques, including coiling, can manage most aneurysms, including complex cases.
- While endovascular coiling offers advantages, long-term results remain a subject of debate.
- Radiology plays a crucial role in the diagnosis, treatment, and follow-up of aneurysmal SAH.
