Inflation-extension behaviour of the human vena saphena magna

Popis výsledku v původním jazyce

Saphenous vein grafts are still frequently used in both coronary and peripheral bypass surgery. Although much work is now being done to deepen our knowledge of the mechanobiology of graft remodelling, these processes are still not completely understood. To contribute to an effort aimed at filling this gap, a pressurization experiment with a tubular sample of the human great saphenous vein was carried out. Our study particularly focused on the so-called inversion point, known from arterial mechanics. Inversion point is the value of the axial prestretch at which a pressurized tube does not move axially. The experiment confirmed that axial inversion takes place in the mechanical response of the prestretched saphenous vein. This means that there is a value of the axial prestretch at which pressure-induced elongation changes to pressure-induced shortening of the inflated tube.
