Neuroendovascular coiling is performed to prevent the blood flow in an aneurysm. An aneurysm is the excessive enlargement of blood vessels lead to a weakness of the blood vessel wall. This helps by sealing the aneurysm, promoting blood clotting around the coils and reducing pressure on its outer wall. The endovascular coiling treatment is usually performed under general anesthesia by a neurosurgeon or an interventional neuroradiologist using fluoroscopic imaging guidance.
