What is the typical treatment for a saccular or berry aneurysm?

In the management of a saccular or berry aneurysm, surgical clipping is often considered a standard treatment option, especially for those that are symptomatic or have a significant risk of rupture. This procedure involves placing a clip across the neck of the aneurysm to isolate it from the circulation, preventing any blood flow into the aneurysm sac and therefore reducing the risk of rupture. Clipping can be performed through craniotomy and requires careful monitoring for complications such as vascular injury or neurological deficits.

Endovascular coiling is another effective treatment option for saccular aneurysms and may also be appropriate in many cases. However, the choice between clipping and coiling is often influenced by the aneurysm's size, location, and morphological characteristics, as well as the patient's clinical scenario. Surgical clipping is distinctly indicated for certain aneurysms where coiling may not be suitable.

Medication therapy is generally not a definitive treatment for aneurysms and serves more in the context of managing symptoms or preventing complications related to subarachnoid hemorrhage. Observation alone is typically reserved for small, asymptomatic aneurysms with a low risk of rupture, not for larger or symptomatic ones.

Thus, surgical clipping remains a fundamental and often necessary intervention for effectively managing the risks associated
