What are the treatment options for Cerebral (Brain) Aneurysms?

Treatment for Cerebral (Brain) Aneurysms aims to repair the blood vessels. There are two types of treatments available - surgical clipping and coiling.

Surgical clipping

Surgical clipping is where craniotomy surgery is performed and a clip is placed across the base of the aneurysm to prevent blood from entering and causing further growth or rupture.


Coiling is filling the Aneurysm with coils of platinum wire or latex to prevent more blood from entering the aneurysm.

There are other treatments available which relieve the symptoms and manage the complications. These include analgesic pain relievers, calcium channel blockers, interventions to prevent stroke from insufficient blood flow, anti-seizure medications, ventricular catheters and shunt surgery and rehabilitative therapy.
