Zusammenfassung
Morphologische Veränderungen der Aorta abdominalis und der Vena cava inferior ein bis sieben Tage nach mildem mechanischem Trauma (Quetschen der Gefäßwand mit einer von Gummi überzogenen Klemme) wurden untersucht. Silberimprägnierte Totalpräparate werden lichtmikroskopisch und Gefäßschnitte elektronenmikroskopisch durch-mustert. Sowohl in der Vena cava als auch in der Aorta abdominalis werden zu allen untersuchten Zeiten folgende morphologische Veränderungen gefunden: Fokale Nekrose, abnorme Überlappung und zum Lumen gerichtete Pseudopodienbildung der Endothelzellen und der medialen glatten Muskelzellen, die oft durch Fenestrae der elastischen Membran in die Intima hineindringen. Intramurale Leukocytenanhäufungen wurden nur in der Vena cava gefunden. Eine Vermehrung der Grundsubstanz war nur im Bereiche der Myointimalzellen der Aorta sichtbar. Herkunft und Bedeutung der oben erwähnten Gefäßveränderungen werden diskutiert.
Summary
The morphological changes of the abdominal aorta and inferior vena cava were studied from one to seven days following application of mild mechanical trauma (compression of the vessel wall with a clamp covered by rubber tubing). Both light microscopy of silver-stained surface preparations and electron microscopy of sectioned vessels were performed. The following morphological changes were observed in both the vena cava and abdominal aorta at all time sequences investigated: focal necrosis, abnormal overlapping of endothelial cells and pseudopod-formation from them usually directed into the lumen; and pseudopod-formation from medial smooth muscle cells, often passing into the intima via fenestrations in the elastic membrane. Leucocytes accumulated in the vessel wall only in the vena cava, whereas the ground substance increased only around myointimal cells of the aorta. The genesis and significance of the above changes are discussed.
