[Experimental model of isolated arterial stenosis].

Abstract

The production of an arterial stenosis in an experiment is performed mainly by means of starvation ligatures or constrictors. In this way the produced stenosis does not allow to exercise reconstructive surgical interventions during the training in the angio-surgery. We produced the model of an isolated arterial stenosis by means of an anodic direct current in extravascular application. The stenosis was demonstrated by angiography and measurement of the blood flow. Measurements of the oxygen tension in the femoral artery and vein showed a decrease of the values after producing the stenosis. This method makes it possible to carry out a training of any kind of reconstructive interventions.
