Predicting changes in blood flow in patient-specific operative plans for treating aortoiliac occlusive disease.
Traditionally, a surgeon will select a procedure for a particular patient on the basis of past experience with patients with a similar state of disease. The experience gained from this patient will be selectively used when treating the next patient with similar symptoms. This article describes a surgical planning system that was developed to enable a vascular surgeon to create and test alternative operative plans prior to surgery for a given patient. One-dimensional and three-dimensional hemodynamic (i.e., blood flow) simulations were performed for rest and exercise for operative plans for two aorto-femoral bypass patients and compared with actual postoperative data. The information obtained from one-dimensional (volume flow distribution and pressure losses) and three-dimensional (flow, pressure, and wall shear stress) hemodynamic simulations may be clinically relevant to vascular surgeons planning interventions.
