Computed tomographic diagnosis of abdominal aortic aneurysm.
Diagnosis of abdominal aortic aneurysms has been facilitated by the use of computed tomography (CT). This is illustrated by four cases, presented here, two of which were diagnosed by angiography and CT, and two having been operated upon on the basis of CT diagnosis alone. We feel that CT can replace angiographic studies by supplying the surgeon with all the pre-operative details needed. CT is more accurate than angiography, since the latter may underestimate the true diameter of aneurysms, or can even give false-negative results. With CT it is possible to detect signs of rupture or pre-rupture states of aneurysms that have not been suspected on angiographic or clinical grounds.
