摘要
目的了解心电图同期CT脑血管造影(CTA)技术对于未破裂动脉瘤的小泡样突起诊断的准确性。方法2004年间对15例患者进行了心电图同期CTA检查。结果其中10例患者在心电图同期CTA图像上发现有搏动部位存在,提示动脉瘤上有小泡样突起,手术中也有同样发现。切除的15例动脉瘤标本组织学检查均发现肌层和内弹力层部分或完全缺失,而有小泡的10例动脉瘤中发现胶原层减少,这与小泡样突起的存在相吻合。结论心电图同期CTA可用于未破裂动脉瘤的小泡样突起的诊断,其准确性可用标本的组织学检查加以证明。
Objective To investigate the accuracy of electrocardiogram（ECG）-gated CT angiography in the detection of bleb in unruptured aneurysm. Me＇thods In 2004, 15 unruptured aneurysm patients received ECG-gated CT angiography examination. Results Ten of the patients had bleb and the bleb was detected as the pulsation site in ECG-gated CT angiogram. Surgically excised specimen were stained and histological investigation revealed that there were partial or complete absence of tunica media smooth muscle and the internal elastic lamina layer in the aneurysm wall in 15 cases. A sudden reduction of collagen layer was noted in 10 cases with bleb. Conclusion ECG-gated CT angiography can be used in the bleb detection of unruptured aneurysms, and its accuracy can be verified by histological examination.
