| Popis: | Computed tomography angiography (CTA) of the aorta is an accepted standard diagnostic procedure for preoperative evaluation and planning of endovascular treatment of abdominal aortic aneurysms (endovascular aortic repair EVAR). The CTA method delivers all relevant anatomical and morphological information on the underlying pathology of the aorta and pelvic axes. Various software solutions are available for multiplanar reconstruction of the CT data for exact measurement of the access routes and landing zones and are essential components of individualized operation planning. The synthesis of all CT-based information allows a safe and exactly targeted release of the stent graft in the aorta. Furthermore, the periprocedural radiation dose can be reduced by a precise preoperative planning of the positions to be irradiated during implantation. |
