Thrombus formation in large aneurysms is well recognized. However, thrombi in small aneurysms with subsequent embolization into intracranial vessels is infrequently identified or suspected. A series of cases in which this phenomenon has occurred is documented. Since many of these examples present embolic disease without suspicion of aneurysm, definitive diagnosis can only be accomplished by angiography. The importance of this study should be emphasized since embolic disease is usually assessed only by computed tomography which fails to delineate the embolic source.
大型动脉瘤内血栓形成已得到充分认识。然而，小动脉瘤内血栓形成并随后栓塞入颅内血管的情况却很少被发现或怀疑。本文记录了一系列发生这种现象的病例。由于许多此类病例表现为栓塞性疾病而未怀疑有动脉瘤，因此只有通过血管造影才能做出明确诊断。本研究的重要性应予强调，因为栓塞性疾病通常仅通过计算机断层扫描进行评估，而该检查无法确定栓子来源。
