What is an aneurysm embolization?

The cerebral aneurysm, a weakness of the wall of the artery, is a serious illness. If the cerebral aneurysm breaks, the internal hemorrhage could cause a spill or the death. In less serious cases, the growing of an aneurysm can compress the nerves and the surrounding cerebral tissue and cause paralysis, headache, neck pain, upper back pain, and nauseas and vomits. The brain angiography, the tomography and the nuclear magnetic resonance (NMR) can detect the brain aneurysms before they break. The neuroradiologist carries out the embolization with detachable coil to control the danger an aneurysms implies. The neuradiologist inserts a tube called catheter in an artery of the leg. This catheter naviggates through the body until arriving to the place of the aneurysm. Once in their position, the radiologist places one or more coils (hairsprings) in the aneurysm through the catheter. The reaction of the human body is to form a clot of blood around the coil, whicht blocks the aneurysm. The embolization with coil is more commonly used to treat aneurysms and fistula of the brain when the open surgery is dangerous. The coils prevent the break and the growing of the aneurysm or fistula because they form a clot of blood that obstructs the flow of blood to the affected area.
