Aneurysm clipping is a microsurgical technique used to prevent blood flow into the brain by a ruptured or leaking aneurysm.
The goal of aneurysm clipping is to isolate the aneurysm from the normal blood circulation through the brain without blocking off any nearby arteries.
During this microsurgical procedure, a tiny titanium clip is used to stop blood flow into the aneurysm. A craniotomy is then performed to create an opening in the skull in order to access the aneurysm in the brain. The clip is then placed on the opening of the aneurysm and remains inside the brain permanently, working as a tiny coil-spring clothespin.
