title: [Pre- and postoperative computer tomography diagnosis of aortic isthmus stenosis].
abstract: In individual cases the computed tomography renders possible the ascertainment of the coarctation of the aorta. Despite modified examination method (secondary section technique, continuous application of contrast medium) the reliability is insignificant. Therefore, the method cannot be recommended for the primary diagnostics of the coarctation of the aorta. The computed tomography is extraordinarily suited for the detection of aneurysms of anastomoses after operation of coarctations of the aorta. In 50 computed-tomographic examinations of 48 patients 11 times an aneurysm could be ascertained. This high proportion of late postoperative complications is above all to be traced back to the surgical suture material used in the sixties. There were only two falsely positive findings, in which cases also here relevant pathological changes were present. The computed tomography can more exactly than the aortography adopt a definite attitude to the question of the dissection of prostheses or to pseudoaneurysms.
