WebAneurysm flow diversion is a minimally invasive treatment in which a device known as a neurovascular stent placed in the parent blood vessel of a brain aneurysm may divert blood flow away from the aneurysm. Over time, blood flow into the aneurysm may slow down, eventually ceasing to enter the aneurysm altogether. As the body’s natural healing ... WebFlow-diverting stents are vessel reconstruction devices that promote the reduction of blood flow inside the aneurysm, resulting in gradual thrombosis while preserving the flow in the parent artery. The stent also acts as a cast for the reformation of the vessel wall through the endothelization of the aneurysmal neck [9] .
