[Diagnostic value of angiodynography in pulsating space-occupying lesions]

19 patients with undiagnosed pulsating masses occurring after angiography, by-pass surgery or trauma were examined by conventional ultrasound, duplex sonography, angiodynography and, in some cases, by angiography. There were nine pseudo-aneurysms and 13 haematomas; in each case the diagnosis was made by duplex sonography and by angiodynography. Pseudoaneurysms show the following typical signs on angiodynography: 1. Typical wave form during spectrum analysis, 2. Specific blood-flow pattern into and out of the aneurysm, 3. Turbulence within the aneurysm. Angiodynography provides a reliable, rapid and exact means of diagnosis. In future, this will be able to replace more invasive procedures such as angiography.
