[Color Doppler echocardiography in the diagnosis of XXXX and aortic wall abscesses].

In eleven @entity1 with @entity1580 or perforated endocarditic aortic wall abscess cavity, the diagnostic usefulness of Color Doppler Echocardiography (CDE) for the identification of true and false lumen as well as the perforation jet was assessed by comparison with the findings of angiography, digital subtraction angiography, computed tomography and surgery. The information gained in addition to that of these procedures, as well as to that of the four conventional echocardiographic techniques was evaluated. Six @entity1 had @entity1580 or III; in all of them the diagnosis had been established with conventional ultrasonic techniques. Similarly, in all @entity1 with @entity1580 , a clear differentiation between true and false lumen in the aortic root and ascending aorta could already be made by grey-scaled echocardiography. In these @entity1 , however, CDE made the additional demonstration of the perforation jet into the false lumen possible. In those three @entity1 with @entity1580 of @entity164 as well as in the abdominal aortic region of DeBakey type I, color Doppler echocardiography was the only method to define true and false lumen and to clearly localize the perforation sites. Two further @entity1 were found to have a small, local dissection, which could only be assumed by conventional echocardiography; the color Doppler M-mode image led to a clear diagnosis. In three @entity1 an @entity733 of the aortic wall could be detected by conventional echocardiography. Two-dimensional color Doppler echocardiography additionally enabled us to visualize the presence and the course of perforation flows. In two @entity1 color-coded Doppler echocardiography made it possible to detect perforations in regions which could not be localized either with conventional echocardiographic techniques or the above-mentioned control procedures.
