摘要
目的 探讨蛛网膜下腔出血血管造影阴性病例动脉瘤自闭假说的真实性 ,以及导致动脉瘤自闭发生的相关因素。方法 回顾性分析临床上出现的经全脑血管造影证实的 4例明确的动脉瘤病例动脉瘤自闭现象 ,对导致动脉瘤自闭发生的因素进行了分析。结论 在蛛网膜下腔出血全脑血管造影阴性时 ,要考虑到动脉瘤自闭的可能 ,不论是否巨大动脉瘤 ,均有发生自闭的可能。与动脉瘤自闭有关的因素有 :血流速度的改变、动脉瘤的大小、形态。
Objective To discuss the hypothesis of the intracranial aneurysmal spontaneous occlusion in negative angiogram in subarachnoid hemorrhage(SAH), and study the factors related to intracranial aneurysmal spontaneous occlusion.Methods Four cases aneurysms spontaneous occlusion after panangiographical diagnosis. were reviewed retrospectively. Factors causing intracranial aneurysm self healing were analyzed.Conclusions For the negative angiogram in SAH, we should consider the possibility of aneurysmal spontaneous occlusion. The intracranial aneurysm, giant or not, has inclination of self healing. The other factors related to aneurysmal spontaneous occlusion are: the blood flow velocity, the aneurysmal size, the shape, the location and the direction of the dome.
