Aneurysm Clipping and Coiling
St. John Neurosurgical Center offers clipping and coiling procedures for aneurysms.
An aneurysm is a weakened area in the wall of an artery resulting in ballooning or widening that could cause the artery to burst.
Aneurysm clipping is the most common surgical treatment for cerebral aneurysms. During this procedure, a metal clip is placed at the base of the aneurysm to block blood flow.
Aneurysm coiling, also called endovascular coiling, also blocks blood flow to an aneurysm. However, this minimally invasive procedure involves guiding a catheter from the groin to the aneurysm in the brain. Thin metal wires are coiled into a ball inside the aneurysm. Blood clots form around the coil to prevent the aneurysm from bursting or bleeding. Stents may also be used to hold the coils in place.
