ABSTRACT
In the process of radical resection of abdominal malignant tumors, large blood vessels are often invaded, which not only increases the difficulty of operation, but also directly affects the curative effect and prognosis. As the concept of expanded radical surgery combined with vascular resection and reconstruction and related techniques have been gradually recognized, surgeons have begun to use autologous, allogeneic or artificial vessels to repair the defective blood vessels during surgery, so as to achieve the effect of radical surgery. However, due to the short comings of these materials, scholars have been looking for better alternatives. In view of the fact that the mesothelial cells of the peritoneum and the endothelial cells of the blood vessels have many similarities in embryology, histology and physiology, and peritoneum is also easier to obtain than autologous, allogeneic or artificial vessels. To make the autologous peritoneum into a patch for repairing the defective blood vessels is feasible in theoretical and technical. In this paper, we review the current research progress of autologous peritoneal patch to repair blood vessels of defect.
