National Institutes of Health Better pictures have made it possible to study medical illnesses in great detail. Other research projects include studies of the effectiveness of microsurgical clipping and endovascular surgery to treat ruptured and unruptured aneurysms, the use of various types of coils and other materials to block the flow of blood into the aneurysm, and the influence of blood flow speed and pressure on the success or failure of treatment. Earlier studies had shown that aneurysm growth was a risk factor for aneurysm rupture. What is a cerebral aneurysm?
