With the progress of abdominal surgery technology and the development of comprehensive tumor treatment, abdominal surgery combined with vascular resection became more and more popular. As one of the alternative materials for vascular resection and reconstruction, allogeneic blood vessels had their unique advantages in morphology and histocompatibility. However, there was still a lack of unified application standards for the source, preservation, reconstruction methods and techniques of allogeneic blood vessels and the management after reconstruction. To this end, academic chapters such as the Society of Liver Transplantation, China International Exchange and Promotive Association for Medical and Health Care organized relevant domestic experts to participate in the discussion and formulation of this guidelines. The guideline mainly aimed at the source, preservation, clinical application and postoperative management of allogeneic vascular, and gave 10 recommendations based on existing evidence, aiming to guide clinical practice through evidence-based, and provide guiding suggestions for the application of allogeneic vascular transplantation in abdominal surgery.
