| Summary: | Aim. Hemodynamic shifts in the brain, developing due to carotid surgery (carotid endarterectomy or stenting) might be the cause of perioperation strokes. Assessment for hemodynamic shifts is important. The aim of current study was to develop methodics of cerebral hemodynamics assessment at pre-operation and post-operation periods of carotid endarterectomy.Material and methods. The authors propose a mathematical model for preoperation analysis of hemodynamics changes in extracranial regions of brachiocephalic arteries after carotid endarterctomy. The development of mathematical model was based upon the data from pre- and postsurgery duplex scan and CT-angiography.Results. The results showed good prediction capacity for the shifts in cerebral hemodynamics, using the developed mathematical model.Conclusion. Study results make it to assess cerebral hemodynamis without supplementary investigations. The model includes and represents real anatomy and quantitative hemodynamics parameters by the CT-angiography and duplex scan of the vessels. |
