Catheter

Blocked or narrowed blood vessels are a cause of acute deseases such as stroke or heart attack. Their treatment using minimally invasive techniques - called endovascular procedures, in which a catheter is pushed through the vessels to the diseased site - can be successfully performed today. The main therapies are the mechanical recanalization and holding a vessel permanently open by a vascular prosthesis (stent). Another important aspect of endovascular procedures is the treatment of cerebral aneurysms with implants, which modify the hemodynamics in the aneurysm and thereby positively aids recovery.

One focus of minimally invasive neuroradiology represents the treatment of aneurysms. The aim of these interventions is to reduce the inflow of blood through targeted modification of hemodynamics in aneurysm to the extent, for example through coils or flow diverter, so that it is no longer clinically relevant. With modern imaging techniques it is possible to map the three-dimensional structure of the cerebral vascular tree, including existing pathologies. These data form the basis for computational fluid dynamic (CFD) simulations in order to simulate the change of patient-specific hemodynamics by the available implants. Extensive preparations were made in Magdeburg in this area.
