Abstract
INTRODUCTION
Computed tomography angiography (CTA) can add information to digital subtraction angiography (DSA) in selected cases of aneurysms of the circle of Willis.
CLINICAL CASES
- Patient with progressive visual loss and headache. CT and DSA showed an image of partially thrombosed suprasellar aneurysm. CTA better defined the relationship between the lesion and regional vessels. 2. Woman with subarachnoid hemorrhage (SAH). CTA defined the aneurysmal neck and its relationship to the clinoid process. 3. Man with SAH, CT and DSA showed an arteriovenous malformation and three arterial aneurysms one of which was in a tortuous vessel. CTA confirmed digital angiographic data.
CONCLUSION
CTA is a new image technique that can either add or confirm DSA findings in complex aneurysms of the circle of Willis.
摘要
引言
在某些 Willis 环动脉瘤病例中，计算机断层血管造影（CTA）可为数字减影血管造影（DSA）补充信息。
临床病例
- 一名渐进性视力丧失和头痛患者。CT 和 DSA 显示鞍上动脉瘤部分血栓形成的影像。CTA 更清晰地界定了病变与局部血管的关系。2. 一名蛛网膜下腔出血（SAH）女性患者。CTA 明确了动脉瘤颈及其与床突的关系。3. 一名 SAH 男性患者，CT 和 DSA 显示动静脉畸形和三个动脉瘤，其中一个位于迂曲血管中。CTA 证实了数字血管造影数据。
结论
CTA 是一种新的成像技术，可在 Willis 环复杂动脉瘤中补充或证实 DSA 检查结果。
