Cerebral aneurysm coiling is a minimally invasive procedure similar to a cerebral angiogram. This procedure uses contrast and X-rays are taken for images of the blood vessels and aneurysm. In addition to taking pictures, a catheter is inserted through the patient's groin and is directed into the blood vessels and then into the aneurysm. An endovascular specialist uses X-ray guidance to place soft platinum micro-coils into the aneurysm to detach them. The coils stay within the aneurysm and act as a mechanical barrier to blood flow. The aneurysm is sealed off to the rest of the brain. This procedure can lessen a patient’s hospital stay and recovery is much quicker compared to traditional surgery.
