description: The flow in models of temporary vascular prostheses of various configurations has been studied using computational technologies. The aim of the study was to determine the most functionally advantageous types of vascular prostheses used for temporary restoration of blood flow in case of damage to the main arteries of the extremities. In the course of the study, numerical studies were conducted on loop-like models of temporary vascular prostheses. In particular, the features of the entrance edge of the prosthesis were taken into account, which can significantly affect the developing course and, consequently, the sites of possible thrombosis. The results obtained made it possible to determine the most functionally advantageous types of temporary vascular prostheses, which provide optimal conditions for restoring blood flow and minimize the risk of complications.
