Which intervention is standard for managing suspected subarachnoid hemorrhage?

• A. Refer for surgical clipping or endovascular coiling
• B. Administer broad-spectrum antibiotics only
• C. Initiate chemotherapy
• D. Observation without imaging

Answer: (A)

Securing the ruptured aneurysm to prevent rebleeding is the standard intervention for suspected subarachnoid hemorrhage. When SAH from a ruptured intracranial aneurysm is suspected and confirmed, the immediate goal is to definitively isolate the aneurysm from the circulation. This is done with surgical clipping or endovascular coiling, both of which effectively prevent further bleeding and improve survival and outcomes. Clipping surgically places a tiny clip across the aneurysm neck, while coiling fills the aneurysm with coils to promote thrombosis, preserving the parent vessel. The choice between these approaches depends on aneurysm characteristics and patient factors, but either method is the established standard of care. Other management steps are important but do not address the bleeding source. Antibiotics would treat infection, not a hemorrhage; chemotherapy is for malignancy, not acute SAH; observation without imaging would miss the diagnosis and fail to prevent fatal rebleeding. After securing the aneurysm, additional care like blood pressure optimization and agents such as nimodipine may be used to reduce vasospasm risk and improve outcomes.
