During the surgery of atherosclerotic plaques removal, a longitudinal artery incision is made. Frequently used practice is sewing a patch in the incision area. It reduces the risk of narrowing of the artery but also causes its widening. The channel expansion leads to the enhancing separation of the boundary layer and vortexes creation. The selection of the patch size is based on the surgeon’s experience. The purpose of the studies is to determine a new geometric concept of a patch. The resultingpatch is fully parameterizedand can be influenced by its geometric shape, adapting it to the patient’s diameter. Simulations of blood flow in the artery were performed, with the patch used during the surgery and a patch developed by the authors. The analysis of the flow field in terms of the wall shear stresses (WSS) and velocity distribution has shown, that the patch developed by authors give the most satisfactory results.
