Currently, when autologous grafts cannot be utilized, other grafts can come from animals (xenografts), cadavers (allografts), or made from synthetic materials, such as tubes of polytetrafluoroethylene (PTFE). The xenografts and allografts are susceptible to rupturing (aneurism), hardening (calcification), and blockage (thrombosis), which can result in harm to the patient. The biomaterials are also prone to thrombosis and changing size of the opening (both increasing and decreasing) due to blood flow pressure and growth on the inside of the tube, respectively [3]. | Currently, when autologous grafts cannot be utilized, other grafts can come from animals (xenografts), cadavers (allografts), or made from synthetic materials, such as tubes of polytetrafluoroethylene (PTFE).
