ABSTRACT
Objective:
To anslysis the hemodynamic states of vertebrobasilar dolichoectasia based on computational fluid dynamics technique.Methods:
The original DICOM format image data from a patient with vertebrobasilar dolichoectasia (VBD), were imported by the Mimics software directly,and the 3D Objects were constructed.The simulation of model was made with Ansys software, the hemodynamic pa-rameters such as streamlines, wall shear stress( WSS) and wall pressure were described.Results:
There was stable laminar flow in proximal basilar artery and was no blood flow mixed by bilateral vertebral arter-y.However, Spiral flows were appeared in distal tortuous basilar artery.The low WSS regions in the ver-tebra-basilar junction section and inferior segment of basilar artery were coincide with the high wall pres-sure regions.It could be speculated the initial growth regions might be located in the vertebra-basilar junction section and inferior segment of basilar artery.Local regions with low WSS and high wall pressure might be associated with the occurrence and development of VBD.Conclusion:
CFD numerical simula-tion maybe can provide a theoretical basis for the role of hemodynamic factors in occurrence and develop-ment of VBD.
