The plastic substitution of the aorta and its large branches may be considered largely solved today. For this purpose preference is given to highly porous, thin-walled double velour prostheses. The search for a biocompatible plastic substitute for small caliber arteries and the large veins of the body (portal vein, vena cava, iliac veins) is proceeding in two directions at the present time: on the one hand towards optimized bioprostheses and on the other hand towards plastics which apply the principle of microporosity or impermeability with the creation of antithrombogenic inner surfaces. In this respect expanded polytetrafluoroethylene and coating with carbon are very promising.
如今，主动脉及其主要分支的塑料替代在很大程度上可被视为已得到解决。为此，人们更倾向于使用高度多孔、薄壁的双层丝绒假体。目前，针对小口径动脉和人体大静脉（门静脉、腔静脉、髂静脉）寻找生物相容性塑料替代品的研究正朝着两个方向进行：一方面朝着优化生物假体的方向发展，另一方面朝着应用微孔性或不渗透性原理并创造抗血栓形成内表面的塑料方向发展。在这方面，膨体聚四氟乙烯和碳涂层非常有前景。
