What surgical intervention is used for treating aneurysms associated with subarachnoid hemorrhage?

1. Clipping

2. Bypass grafting

3. Shunting

4. Ligation

The correct answer is: Clipping

Clipping is a highly effective surgical intervention for treating cerebral aneurysms, particularly those associated with subarachnoid hemorrhage. This procedure involves the placement of a metal clip at the base of the aneurysm to prevent blood from entering it, thereby reducing the risk of rebleeding and potential complications. By securing the aneurysm, clipping helps to protect the surrounding brain tissue from the effects of the hemorrhage. Subarachnoid hemorrhage often results from the rupture of an aneurysm, leading to bleeding in the space surrounding the brain. Timely intervention is critical, as rebleeding can occur if the aneurysm is not addressed. Clipping is typically performed through a craniotomy, allowing direct access to the aneurysm for precise placement of the clip. Other surgical options, such as bypass grafting and shunting, are generally not utilized for direct treatment of aneurysms. Bypass grafting is more relevant in cases of occlusive cerebrovascular disease, while shunting may be employed to manage complications from increased intracranial pressure or to reroute cerebrospinal fluid rather than to address the aneurysm itself. Ligation may be considered in very specific cases but is not the standard approach for aneurysm treatment. Thus, clipping
