Computation of the change in length of a braided device when deployed in realistic vessel models.

摘要: An important issue in the deployment of braided stents, such as flow diverters, is change length, also known foreshortening, underwent by device when released from catheter into a blood vessel. The position distal end controlled interventionist, but knowing priori proximal not trivial. In this work, we assess and validate novel computer method to predict length that stent will adopt inside silicon model an anatomically accurate Three-dimensional rotational angiography images aneurysmatic patients were used generate surface models vessels (3D meshes) then create them. A was deployed each measure its length. same stents on virtually 3D meshes using being evaluated. applied five placements three different models. adopted real varies between 15 30 % specified manufacturer. final predicted within estimated error measured provides, few seconds, vessel, showing estimation for cases studied.
