The Effect of Tissue Adhesion Due to Encapsulation on Anastomosis Strength and a Comparative Study of Vascular Substitute


The anastomosis strength of vascular substitute and blood vessel is supported not only by the suture thread but also by tissue adhesion due to encapsulation of vascular substitute In this paper, the in vitro and combined in vivo and in vitro mechanical tests were earned out to estimate the anastomosis strength between a vascular substitute and a blood vessel, good encapsulation of inner wall of the vascular substitute around the anastomosed part was found to be effective to enhance anastomosis strength Furthermore, these results were compared with the expenmental result of the anastomosis being performed by using suture thread only Concerning the problem of the anastomosed part of the blood vessel with the vascular substitute, both effects mentioned above were found to be important requisites for the design of good functional vascular substitutes suitable for anastomosis Finally, the significance of the in vitro and combined in vivo and in vitro mechanical tests are discussed
