A stroke is a medical emergency that can result in permanent brain damage, speech and movement complications, and death if not promptly diagnosed and treated. It is caused by the sudden loss of oxygen to the brain, either by the blockage of blood flow or the sudden loss of blood. The loss of oxygen to the brain can be the result of blockage of a major vessel in the neck (carotid artery). Once the blockage is detected by an interventional radiologist, angioplasty can be performed in order to widen the narrowed artery. Non-invasive techniques such as angioplasty and stent placement can help restore blood circulation and can usually have the patient back to a normal routine within hours after the procedure. Angioplasty involves the insertion of a very small balloon into the narrowed vessel. The interventional radiologist increases the diameter of the artery by slowly inflating the balloon. A small mesh like metal called a stent can also be inserted into the vessel thereby helping to maintain and strengthen the artery.
