[3-D angiography in diagnosis and treatment of intracranial aneurysm].
OBJECTIVE
To summarize the results of initial application of three-dimensional angiography (3D-Angio) in diagnosis and treatment of intracranial aneurysms.


METHODS
From August 1999 to January 2001, standard digital subtraction angiography (two-dimensional angiography, 2D-Angio) and 3D-Angio(obtained by reconstruction of rotational angiography) were performed in 65 patients with confirmed or suspected aneurysms.


RESULTS
Sixty-six aneurysms were found in 60 patients and nothing was found in 5. Of 66 the aneurysms (60 cases), 46 (43 cases) were treated by intrasaccule embolizotion with coils, 3 (3 cases) by occluding the parent artery with detachable balloon, 10 (10 cases) by surgery, and 1 (1 case) by combination of extracranial-intracranial bypass and balloon occlusion of parent artery. Six (3 cases) were not treated. Two aneurysms that could not be detected by 2D-Angio were diagnosed by 3D-Angio. Three aneurysms that were difficult or dangerous to embolize by 2D-Angio were embolized successfully with the help of 3D-Angio. Three aneurysms seemed to be embolized on 2D-Angio were proved impossible to be embolized on 3D-Angio. Of the 46 aneurysms embolized intrasaccularly, 38(82.6%) were completely embolized on 2D-Angio. In the 38, 8 had residual aneurysm on 3D-Angio.


CONCLUSIONS
More accurate diagnosis and secure treatment of intracranial aneurysm can be reached by 3D-Angio.
