Outcomes of cold-stored venous allograft for below-knee bypasses in patients with critical limb ischemia

Cold-stored venous allografts may be used for performing infragenicular revascularization for CLI with acceptable safety and efficacy results despite poor long-term patency. Their level of performance remains inferior to autologous vein sources but seems comparable to alternative allografts or prosthetic conduit. Their availability is a major advantage compared with other biologic alternative sources.
