Endovascular expanding metallic stents were percutaneously implanted in the iliac arteries and veins of pigs. The vessels had been stenosed by a ligature of catgut 4 weeks prior to this. Platelets were labeled with Indium 111 and the deposition onto the dilated and stented areas was dynamically registered for 240 min with a scintillation camera. All six arterial and six venous stents remained patent throughout the examination period. At the site of arterial stenting there was an increase, of deposited activity, and in the veins a decrease. These experimental findings support the use of endovascular stents after dilation, especially in venous stenoses.
血管内扩张金属支架经皮植入猪的髂动脉和静脉。在此之前4周，血管已用肠线结扎造成狭窄。血小板用铟111标记，并用闪烁相机动态记录240分钟内其在扩张和植入支架区域的沉积情况。在整个检查期间，所有6个动脉支架和6个静脉支架均保持通畅。在动脉支架置入部位，沉积活性增加，而在静脉中则减少。这些实验结果支持扩张后使用血管内支架，尤其是在静脉狭窄的情况下。
