Microvascular phantoms are promising tools employable in simulations of realistic surgical scenarios for the development of surgical experience. Being free of ethical issues and customizable to patient-specific anatomies, they represent optimal alternatives to animal and cadaver training and a good solution for preoperative planning. Nevertheless, the adoption and the effectiveness of these simulations heavily relies on the ability of the phantoms to accurately mimic the biomechanical properties of human blood vasculature. In order to achieve this goal, available manufacturing technologies are successfully used to produce phantoms with reduced thickness, but with the limitation of resembling only a limited range of real conditions due to manufacturing methods constraints.
