In this paper, we discuss a technique for weakly enforcing ow rate conditions in computational hemodynamics. In particular, we study the eectiveness of cutting lateral branches from the computational domain and replacing them with non perturbing boundary conditions, in order to simplify the geometrical reconstruction and the numerical simulation. All these features are investigated both in the case of a rigid and of a compliant wall. Several numerical results are presented in order to discuss the reliability of the proposed method.
