Zusammenfassung
Die Sonomorphologie des Gerinnungsablaufes sowie die Altersveränderungen an Koageln wurden in vitro untersucht. Klinische Fallbeispiele zeigen die Vielfalt der sonographischen Erscheinungsformen von Blutungen auf. Frische Koagel haben eine solide, leberähnliche Struktur, ältere lassen in ihrer Inhomogenität an verwilderte maligne Tumoren denken. Es wird darauf hingewiesen, daß die Kenntnis des breiten sonomorphologischen Spektrums von Blutergüssen besonders für die sonographische Beurteilung von Problemfällen in Allgemeinchirurgie und Traumatologie von Bedeutung ist.
Abstract
The sonographical morphology of the mechanisms of blood coagulation, as well as the changes occurring the old blood coagulae, were analysed in vitro. Examples of clinical cases show the variety of patterns produced by haemorrhages during sonographical examination. Fresh coagulae have a structure closely resembling that of liver parenchyma, whereas the very inhomogeneous appearance of relatively old coagulae looks more like malignant tumours which seem to be growing as though thev had got out of control. It is pointed out that knowledge of the wide sonomorphological spectrum of the different forms and manifestations oi “haematoma” is of great importance in critical sonographic examination of problematic cases in abdominal and thoracic surgery and also in traumatology.
