CT脑血管造影和临床应用

The Clinical Value of Cerebral CTAngiography

目的：评价ＣＴ脑血管造影临床应用价值。材料和方法：ＣＴ脑血管造影６２例，其中脑动脉瘤２２例，脑动静脉畸形６例，脑肿瘤５例，脑内感染性肉芽肿性病变６例，颈内动脉海绵窦瘘２例，头皮血管瘤１例，正常２０例。其中２２例脑动脉瘤，６例脑动静脉畸形及２例颈内动脉海绵窦瘘还进行了ＤＳＡ检查。结果：６２例ＣＴＡ均能显示１～４级脑动脉结构，有时甚至显示５级脑动脉结构。２２例脑动脉瘤及６例脑动静脉畸形均经ＣＴＡ检出，其诊断结果与ＤＳＡ一致。５例脑肿瘤可见明显“肿瘤染色”。结论：ＣＴＡ为非损伤性血管检查方法，安全简便，其阳性检出率高。

Objective: To evaluate clinical value of cerebral CT angiography (CTA).Materials and Methods:62 cases with cerebral CT angiography, 22 cases are aneurysm, 6 cases with arteriovenous malformation, 5 cases with brain tumor, 6 cases with intracranial infections glanulomatous, 2 cases with carotidcavernous fistula, 1 cases with extracranial hemangioma of soft tissue, 20 cases are normal.Results:All the images of 62 cases demonstrate 1～4 grade branchs of cerebral artery and some of 5 grades. 22 cases of aneurysm and 6 cases of arteriovenous malformation are all found by CTA. The diagnosis is same as DSA. 5 cases of cerebral tuomrs appear “tumor stain”obviously.Conclusion: CTA is a noninvasive angiographic method that is safe and convenient. CTA have important diagnostic value and significance in diagnosis.
