CT三维血管造影诊断出血动脉瘤

Diagnosis of bleeding aneurysm with three-dimensional computed tomographic angiography

目的 评价CT血管造影 (CTA)在颅内动脉瘤破裂后蛛网膜下腔出血诊断中的价值及手术指导意义。 方法 对 6 3例急性蛛网膜下腔出血病人急诊行螺旋CT扫描 ,然后行脑血管三维成像。 结果 发现颅内动脉瘤 2 4例。有 1例阴性经全脑血管造影 (DSA)发现存在动脉瘤。诊断均以手术证实。 结论 CTA对动脉瘤蛛网膜下腔出血是一种微创、快速、准确的诊断技术 ,对于急诊或危重病人应为首选。

Ojective To evaluate the value of computed tomographic angiography (CTA) in the diagnosis of intracranial aneurysml with acute subarachnoid hemorrhage and in making a surgical plan. Methods CTA was performed using Helical CT in sixty three cases of acute subarachnoid hemorrhage Results Twenty four patients with intracranial aneurysms were found by CTA, one case of aneurysm was found by DSA. Diagnostic results were confirmed by operation. Conclusion CTA is a rapid?safe and accurate method in the diagnosis of intracranial aneurysms, particularly for acute and severe patients.
