摘　　要：目的比较颅内动脉瘤破裂与非破裂的形态学,了解破裂动脉瘤的形态学特征。方法将DSA确诊颅内动脉瘤患者171例分为破裂动脉瘤(指自发性蛛网膜下腔出血)组138例和未破裂动脉瘤组33例,分析两组患者的动脉瘤部位分布、大小及形态。结果破裂动脉瘤组138例患者共有149枚囊状动脉瘤。115枚(77%)动脉瘤位于前循环,34枚(23%)动脉瘤位于后循环;124枚(83%)为单囊;25枚(17%)远端可见假性动脉瘤形成。未破裂动脉瘤组33例患者,共34枚动脉瘤。29枚(85.3%)动脉瘤位于前循环,5枚(14.7%)动脉瘤位于后循环;32枚(94.1%)动脉瘤为单囊,2枚(5.9%)动脉瘤为不规则形,所有动脉瘤瘤壁均光整,瘤腔内对比剂均匀。结论破裂动脉瘤常可见典型的表现,包括动脉瘤形态不规则,破口处瘤壁不光整,破口周围易形成假性动脉瘤。Objective To make a further understanding of the morphologic characteristics of unruptured saeeular intracranial aneurysms by comparison with that of ruptured saeeular intraeranial aneurysms. Methods One hundred and seventy-one patients with DSA-proved intracranial aneurysms were divided into ruptured group （consisting of 138 patients with spontaneous subarachnoid hemorrhage） and unruptured group （including 33 patients with no spontaneous subaraehnoid hemorrhage） The loeatian, size and the morphologie characteristics of saceular intracranial aneurysms were analysed. Results （1） A total of 149 saceular aneurysms was found in ruptured group, the aneurysms were located at anterior circulation （n = 115, 77%） or posterior circulation （n = 34, 23%）. Of 149 saeeular aneurysms, single saeeulated type was seen in 124 （83%） and false aneurysm formation at distal site was found in 25 （17%）. （2） Thirty-four aneurysms were revealed in unruptured group, of which 29 （85.3%） were located at anterior circulation and 5 （14.7%） at posterior circulation. Thirty-two aneurysms were of single sacculated type and 2 aneurysms （5.9%） carried irregular shape. Conclusion The typical angiographie manifestations commonly seen in ruptured aneurysms include irregularly shaped lesion, unsmooth aneurysmal wall at the ruptured site and the formation of false aneurysm around the crevasse of ruptured aneurysm.
