| 摘 要： | 目的 探讨不同脑血管成像检查方法CTA、MRA和DSA在自发性蛛网膜下腔出血 (SAH)中诊断动脉瘤的临床价值。方法 4 0例蛛网膜下腔出血患者行DSA检查的同时行CTA或MRA检查 ,其中CTA检查2 3例 ,MRA检查 17例 ,并对其检查结果进行分析。结果 4 0例蛛网膜下腔出血患者中DSA检查共检出动脉瘤 2 5个 ,CTA和MRA共漏诊其中的 8个动脉瘤 ;CTA检出DSA漏诊的 2个动脉瘤 ;所有脑血管成像检查中漏诊的 10个动脉瘤中有 8个其直径小于 3mm。结论 DSA是诊断动脉瘤的最佳检查方法 ;非侵入性检查方法CTA和MRA是DSA的重要补充检查手段 ;小动脉瘤 (直径≤ 3mm)容易被漏诊。

| Abstract: | Objective To evaluate the clinical value of different cerebral angiography methods CTA, MRA and DSA in detecting aneurysm in spontaneous subarachnoid hemorrhage (SAH). Methods Data of 40 cases with spontaneous SAH examed by DSA, MRA or CTA were reviewed respectively. Results In all 40 cases, 25 aneurysms were datected by DSA, among them 8 were missed by CTA and MRA. CTA found 2 lesions which were missed by DSA. 8 of 10 aneurysms missed by angiography were smaller than 3mm in diameter. Conclusions The best diagnosis method of aneurysms is DSA examination, CTA and MRA are important complementary examination methods to detect aneurysm. The aneurysm smaller than 3mm is often missed by noninvasive angiography. |
