[Spiral computerized tomography of acute abdominal aortic aneurysm with optimal 3-D image reconstruction].
43 of 46 consecutive patients with suspected rupture of abdominal aortic aneurysm could be examined by spiral CT. Rupture of an abdominal vessel was found in 18 patients and proved by surgery. Size and extent of the aneurysm, rupture, dissection and vascular occlusion were demonstrated quickly and precisely by spiral CT, planning of surgical intervention could be optimized. Using spiral CT unnecessary explorative laparotomies could be avoided in 25 patients. In addition spiral CT offers the possibility of multiplanar reconstruction images with spatial visualisation of the vascular system. In 8 patients DSA offered no advantage in comparison with 3-D reconstruction images. Spiral CT meets all requirements for quick and reliable diagnosis in suspected rupture of abdominal vessels. Other imaging modalities like digital subtraction angiography are not necessary for evaluation of abdominal aortic aneurysms.
