[Pre- and postoperative diagnosis of an aortic aneurysm by dynamic computed tomography with omission of angiography].
A study which was prospective with regard to the method, showed 41 cases of aortic aneurysms in a collective of 3597 body-CT-examinations (1.14%). By means of CT and its possibility of reconstruction all morphological details of an aneurysm become visible. The course of the vessels to the bowel and to the kidneys are shown with the same excellence as in angiography. However, additional information which angiography cannot supply, is also given, like non-perfused lumen, changed wall structure and perivascular changes. Measurement of flow can be performed in the vessel and in the organ, the arterial supply of which is involved in aneurysmatic disease. The method is non-invasive. This is important for control after operation. Morphological changes of the vessel prosthesis are detected, as well as bleeding and infection. Functional parameters are determined semiquantitatively.
