Abstract

Objective To valuate three-dimensional (3D) digital subtraction angiography (DSA) in endovascular treatment of intracranial aneurysm.Methods In 431 aneurysm,aneurysm shape,aneurysm neck,the feasibility of endovascular treatment and the choosing of the first coil were analyzed at 2D DSA and 3D DSA. Results Comparing with 2D DSA,3D DSA can clearly depicted the aneurysm shape and neck.3D DSA can correctly judge the feasibility of endovascular treatment correctly choose the first coil and judge the degree of embolization. Conclusions 3D DSA is very important in endovascular treatment of intracranial aneurysm.It can provide many valuable informations for endovascular treatmen that 2D DSA can not provide .
