摘要
目的 评价三维数字减影血管造影 (3D DSA)技术诊断脑血管疾病的应用价值。方法 对临床怀疑和确诊为脑血管疾病的 71例患者行常规脑血管数字减影造影 (DSA)和 3D DSA。结果 本组共检查 71例 ,经 3D DSA技术共检出动脉瘤 4 4例 6 4枚、颅内动静脉畸形 (AVM) 19例、血管狭窄致脑缺血8例 (6例颈内动脉狭窄、大脑前动脉闭塞 )。结论 3D DSA诊断脑血管疾病具有极大的临床应用价值。尤其对颅内动脉瘤、AVM、血管狭窄的诊断最为准确、快速。
Objective To evaluate the utility of three-dimensional digital subtraction angiography(3D-DSA) in the diagnosis of cerebral vascular diseases.Methods Seventy-one patients suspected and diagnosed with cerebral vascular diseases underwent conventional DSA and 3D-DSA. Three-dimensional (3-D) reconstructed images were obtained at a separate advantage 4.0 workstation after the rotational images were transferred. The available visualization techniques included maximum intensity projection (MIP), shaded surface display (SSD), and virtual angioscopy (VA). Results Sixty-four aneurysms were found in 44 cases. Nineteen cases were diagnosed as cerebral arteriovenous malformation (AVM) and 8 cases of cerebral ischemia were due to cerebral vascular stenosis (internal carotid artery in 6 cases and occlusion of anterior cerebral artery in 2 cases).Conclusions 3D-DSA is reliable, fast and safe for diagnosis of cerebral vascular diseases, especially involving intracanal areurysms AVM and vascular stenosis.
