Tomographic methods in endovascular aortoiliac treatment
Summary, in English
The specific aim of this thesis was to evaluate:
1. To evaluate the postoperative Computer Tomography Angiography assessment made by vascular surgeons and interventional radiologists after Endovascular Aortic Repair at a tertiary vascular clinic.
2. To evaluate if Cone Beam Computed Tomography can detect intraoperative complications in comparison with Computer Tomography Angiography follow up.
3. To quantify the radiation dose from CBCT in comparison to conventional CTA used for EVAR follow up.
4. Investigate the role of CBCT in the treatment of aortoiliac occlusive disease in order to optimize the primary operation results.
This thesis showed that CBCT is an excellent technique to evaluate the configuration of stents and stentgrafts in the aortoiliac segment. CBCT rendered additional adjunctive procedures that were not detected by conventional imaging technique in the intraoperative setting. However there are limitations with the technique such as the considerable amount of radiation it adds to the procedures and the inability to detect type II endoleaks during EVAR and the use of contrast enhancement is questionable. CBCT facilitates improved intraoperative results in standard EVAR operations and aortoiliac operations. There is a need for further studies to validate long-term results.
