螺旋CT血管造影在颅内血管疾病的临床应用

回顾性分析64例颅内血管的螺旋CT血管造影（SCTA）的影像，其中8例动脉瘤和4例动静脉血管畸形（AVM）进行了数字减影血管造影（DSA）并与SCTA成像对比，6例动脉瘤与其手术结果对比，结果64例SCTA均获成功。其中显示动脉瘤26例；AVM8例，6例较大AVM的供血动脉及引流静脉均显示良好；脑梗塞5例中，1例一侧大脑半球大面积梗塞，显示同侧颈内动脉阻塞，其余29例的SCTA未见异常血管改变，8例动脉瘤和4例AVM的DSA检查及6例动脉瘤进行手术者，其SCTA表现与DSA及手术所见相符，提示SCTA是一种检查颅内血管疾病的无创而有效的方法。

Detection of brain vascular diseases with CT angiography]

OBJECTIVE: To identify the diagnostic effect of spiral CT in brain vascular diseases. METHODS: Sixty four patients underwent CT angiography, including 22 patients with subarachnoid hemorrhage (SAH), 6 patients with oculomotor nerve paralysis, 5 patients with brain substance hemorrhage, 6 patients with arteriovenous malformation (AVM), 4 patients with mass or aneurysm, 5 patients with brain infarction, 16 patients with epilepsy or headache and dizzy. 8 cases also underwent digital subtraction angiography (DSA), 4 cases were performed operation in 64 cases. RESULTS: Spiral computed tomography angiography (SCTA) was all succeeded in 64 cases. 26 aneurysms and 8 AVMs were found by SCTA; in 6 of 8 cases of AVMs, their supply arteries and drainage veins were clearly displayed; SCTAs of 5 cases with substance hemorrhage were normal; in 1 of 5 cases with cerebral hemisphere infarction, its internal carotid obstruction was demonstrated by SCTA; the results of 12 SCTAs were identical with the results of their DSA or operation. CONCLUSION: SCTA is a useful non-invasive inspection method for detecting brain vascular diseases such as aneurysms and AVMs.
