The project deals with the definition of requirements for surgical planning software, which will focus on the surgical use of stent grafts. Furthermore the feasibility of a physically based simulation model for the assessment of stent graft fixation and sealing potential are studied and requirements for a software module for analyzing the results in the medical environment will get defined. The writability of the resulting data is based primarily on existing standards. Required extensions are also included.
A common complication of endovascular aortic aneurysm exclusion is the slipping of the stent graft resulting in insufficient sealing of the vessel. This post-operative complication may be associated with the selection of the vascular implant in the compound. In particular the determination of the stent graft oversize for the fixation of the implant in the vessel is of crucial importance.
