| 目的 探讨颅内动脉瘤破裂出血后在其破口周围所形成的假性动脉瘤与真性动脉瘤复合体的DSA影像学特征及分型。方法 对50例破裂性动脉瘤采用CT及DSA等影像学检查。结果 50个破裂性动脉瘤均表现为出血量不等的SAH,DSA检查均在其破口周围形成假性动脉瘤,其影像特征为在真性动脉瘤腔外可见细小形、圆形或类圆形不规则假性瘤腔,可以根据DSA的影像表现将其分为三型:其中A型(类茶壶型)11例,B型(类葫芦型)27例,C型(类哑铃型)12例。结论 颅内动脉瘤破裂出血后在破口周围可以形成假性动脉瘤,这种假性瘤腔与真性瘤腔一起构成了一个特殊的动脉瘤复合体,其影像特征在DSA上可表现为三种类型。 |

| Objective To discuss the DSA imaging characteristic and classification of the false aneurysm and true aneurysm complex at the rupture position after intracranial aneurysmal subarachnoid hemorrhage. Methods CT scan and DSA imaging were performed in 50 patients (50 ruptured aneurysm). Results 50 ruptured aneurysm showed SAH by different amount of hemorrhage. DSA test all showed the forming of false aneurysm at the rupture position, tiny, round or near round irregular false aneurysm cavity can be found outside the true aneurysm cavity. According to the DSA imaging presentation we can divide them into three types: 11 cases were type A (near teapot), 27 cases were type B (near gourd), 12 cases were type C (near dumbbell). Conclusion The false aneurysm can form around the rupture position after intracranial rupture, the false aneurysm cavity and true aneurysm cavity together form a special aneurysm complex, it's imaging characteristic under DSA can be divided into three types. |
