The goal of endovascular coiling is to isolate an aneurysm from the normal circulation without blocking off any small arteries nearby or narrowing the main vessel. Endovascular describes the minimally invasive technique of accessing the aneurysm from within the bloodstream, specifically during angiography .From the normal circulation without blocking off any small arteries nearby or narrowing the main vessel. Endovascular describes the minimally invasive technique of accessing the aneurysm from within the bloodstream, specifically during angiography. The bloodstream is entered through the large femoral artery in the upper leg (groin area). A flexible catheter is advanced from the femoral artery to one of four arteries in the neck that lead to the brain. While viewing an x-ray monitor, called a fluoroscope, the doctor steers the catheter through the blood vessels. A special dye injected into the bloodstream makes the blood vessels visible on the monitor. The result is a kind of roadmap of the arteries.
