Objective To evaluate three dimensional digital subtraction angiography (3D DSA) in endovascular treatment of carotid stenosis. Methods In 138 patient with ischemic stroke, the shape and stenosis of carotid artery, the feasibility of endovascular treatment and the choice of the stent were analyzed by 2D DSA and 3D DSA. Results Comparing with 2D DSA,3D DSA could clearly depict the carotid artery in shape and stenosis with correct figuring of the feasibility for endovascular treatment and choice of the stent. Conclusions 3D DSA shows the major importance in endovascular treatment of carotid stenosis providing more valuable informations than 2D DSA.
