Advances in vascular surgery are provided in essential extend by improvement of vessel connection methods. Avoiding the detailed history review of vascular suturing methods, I should mention that vascular surgical interventions became successful only since Carrel had formulated four main principles of vascular conjunction: to avoid the slightest lumen narrowing in the place of anastomosis, not to create folds and rough inner surface of the vessel, to put two intimal edges close together, to eliminate possible contact of suture material with blood. Since the implementation ofatraumatic needles, an-ticoagulants, disaggregation and hemodynamic – stabilising agents, surgeons gradually began to give up these principles. Furthermore, after invention of prosthetic grafts the necessity of strict keeping to the rules became questionable, as far as the graft itself appeared to be a factor excluding Carrel's principles. Currently new methods implementing stents appeared in vascular surgery. Nowadays stents are successfully used not only for arterial correction, but for venous as well, including surgery ofportocaval intrahepatic anastomoses, esophageal, urethral, biliary strictures, for prostatic adenomas and neoplasms. Having accepted the new method I decided to expand its possibilities by using a stentfor connection of graft and vessel.
