Show moreThe technique of RSA to determine stent-graft migration and FRSA to study stent-graft dynamics are explained in further detail in CHAPTER 2. CHAPTER 3 and 4 concern the accuracy and feasibility of RSA to detect stent-graft migration in a static model and in a model with pulsatile motion. The results are compared to CT, the current clinical gold standard. RSA requires an aortic reference marker to detect stent-graft migration. A possible aortic reference marker is studied in CHAPTER 4 and 5. In CHAPTER 5, the feasibility of RSA in vivo is described. Furthermore, the position and the number of aortic reference markers required for accurate analysis needs to be clarified. These issues are discussed in CHAPTERS 5 and 6. Plain abdominal radiography is widely used as a low cost method to determine stent-graft migration. In CHAPTER 7, a study on the accuracy and, therefore, clinical applicability of plain abdominal radiography to detect stent-graft migration is described.In CHAPTER 8 the feasibility of FRSA is studied in a model and the method is validated for accuracy and precision. In CHAPTER 9, the first clinical introduction of this technique is reported. To conclude this thesis, the risk of radiation due to imaging for EVAR is evaluated in CHAPTER 10. Show less
