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.
