MoBeStAn: modeling and influence of flow in aneurysms
Aneurysms are balloon-like outgrowths of the arterial vessel walls. The bursting of the aneurysm causes severe internal bleeding and can - depending on the affected vessel - lead to death within a few minutes: ruptured aneurysms always lead to a life-threatening hemorrhage.
The treatment of these outgrowths of vessels in the
peripheral vascular system is an object of vascular surgery in general. The
treatment of intracerebral aneurysms is now performed as minimally invasive as
possible, as the results are better, compared to open surgery. In this case, a
catheter is advanced over the peripheral vascular system in the head and then
into the interior of the aneurysm and this platinum wire filled (coiling), with
the aim of reducing the inflow of blood into the aneurysm to a point where
thrombosis and fibrosis of the aneurysm occurs in the further course. A new
therapeutic strategy is the introduction of implants such as stents in the
vessel at the level of support of the aneurysm, so that the blood flow in the
aneurysm is changed in regard to the qualitative and quantitative, so that the
main flow of blood passes the aneurysm and the wall load is reduced below the
critical value.
