[Value of three-dimensional digital subtraction angiography in diagnosis and planning endovascular treatment of cerebrovascular diseases].
OBJECTIVE
To evaluate the value of three-dimensional (3D) digital subtraction angiography (DSA) in diagnosis and planning endovascular treatment of cerebrovascular diseases.


METHODS
Standard DSA and 3D-DSA were performed in 40 adult patients (aged 21 approximately 74 years) suspected to be with cerebrovascular diseases. The schemes of endovascular treatment were worked out according to the results of 3D-DSA.


RESULTS
Positive rate of standard DSA and 3D-DSA were 85.0% and 95.0% respectively in diagnosis of cerebrovascular diseases. 100% occlusion was achieved in 11 patients with intracranial aneurysms and in 7 patients with arteriovenous malformations, and 100% recanalization was achieved in 9 patients with ischemic stroke. Temporary complications were found in 3 of all patients (7.9%).


CONCLUSIONS
3D-DSA is an ideal tool superior to standard DSA in diagnosis of cerebrovascular diseases and has potential value for evaluating endovascular treatment of cerebrovascular diseases.
