Analysis of hemodynamics on patients of moyamoya disease treated with EDAS

Objective To analyze and compare the change of hemodynamics between pre and post operation of EDAS on patients of moyamoya disease with the way of computational fluid mechanics.Methods We analyzed the hemodynamicses of 29 hemorrhagic and 64 ischemic patients of moyamoya disease with the way of computational fluid dynamics,and compared the pressure and blood flow between pre and post operation of EDAS on patients of moyamoya disease.Results Calculated with the software of computational fluid dynamic,the pressure of the terminal of internal carotid artery decreased (2295.60 ±758.09)Pa post operation on hemorrhagic moyamoya disease.There waa significant difference(P ＜0.01)inthe pressure and blood flow between pre and post operation.Conclusion The operation of EDAS can effectively improve the blood flow and decrease the pressure of terminal of internal carotid artery.
