New frontiers of vascular grafting

Abstract

Vascular grafting can be a very rewarding surgical technique: following surgery, most patients will maintain their autonomy and, in many cases, will be able to return to work. Should small diameter calibre substitutes be required, the autologous saphenous vein is the gold standard. If not available, the expanded PTFE is probably the best choice. For medium and large diameters, the polyesters (Dacron) are recommended provided they have a structure adapted to the needs of patients. However, progress in the last few years is not related to improvements in the grafts themselves. The only breakthrough has come with the success of graft seeding. This is the reason why other approaches have been proposed to restore or improve blood flow in atherosclerotic arteries: medication, sympathectomy, dilatation, laser endarterectomy, stent and spinal cord stimulation. All those approaches have more and more precise indications: they can supplement vascular grafting.
