      Abstract

      The elastic properties of various arterial prostheses were investigated quantitatively before and after their use as arterial grafts. The elastic behavior of different arterial substitutes varied widely. Of the synthetic prostheses studied, only the cloth tubes of the Helanca type had physical properties similar to those of normal arteries. All “elastic” arterial substitutes tested—homografts, heterografts, and the Helanca type of synthetic tubes—soon stiffened after implantation. Synthetic prostheses appeared to stiffen more rapidly after implantation than did the arterial segments tested, though the process in the latter was virtually complete in 6 months. The volume distensibility coefficients and tensionlength responses of both implanted synthetic tubes and arterial segments declined to near those of scar tissue tubes. Evidence is presented to support the concept that these reductions are caused by the scar tissue which is deposited about the implanted arterial substitutes.
