The treatment of wide-necked cerebral aneurysms[1] represents a challenging problem for neurosurgeons. The recent development of stents has provided clinicians with the ability to treat these aneurysms while keeping the parent vessel patent.  Flow Diversion is an endovascular technique where, instead of placing coils inside the aneurysm sac, a cylindrical, metallic, mesh stent is placed in the parent blood vessel across the aneurysm neck. These stents differ from traditional stents used for heart procedures in that they divert blood flow away from the aneurysm dome. The presence of a metallic stent within the artery lumen increases the risk of thrombosis (clotting of the blood) and stroke, and requires the patient be maintained on two anti platelet agents (usually aspirin and another agent) for a period of six months until the stent is incorporated into the artery wall.
