Summary

A method for investigating stretching of small blood vessels is presented. Stress and strain properties of the isolated parasagittal bridging veins were studied. These veins were stressed along their long axis and torn apart at various constant strainrates. The bridging vein's strain capacity was found to be dependent on strain rate, maximal strain was markedly reduced as the rate was increased. The maximal tension in the veins increases as the time to tearing decreases. The tearing tension was shown to be lower for bridging veins as compared to larger veins (femoral, popliteal, inferior vena cava).

Zusammenfassung

Eine Methode zur Untersuchung der Reißfestigkeit bei Streckung kleiner Blutgefäße wird beschrieben. Die Spannungs- und Dehnungseigenschaften isolierter parasagittaler Brückenvenen (Vv. cerebri sup.) wurden untersucht. Die Venen wurden in ihrer Längsrichtung belastet und rissen bei verschiedenen konstanten Dehnungsgeschwindigkeiten. Das maximale Dehnungsvermögen wurde bei größerer Dehnungsgeschwindigkeit stark herabgesetzt. Die maximale Spannung in den Brückenvenen stieg, wenn die Zeit bis zum Abriß kürzer war. Die Zerreißspannung war für Brückenvenen geringer als für größere Venen (V. femoralis, V. poplitea, V. cava inf.).
