目的：探讨颅内动静脉畸形（ＡＶＭ）的ＤＳＡ形态学征象。材料和方法：收集经ＩＡＤＳＡ诊断为颅内ＡＶＭ的１８３例ＤＳＡ片，分析颅内ＡＶＭ的形态学特征。结果：表浅部位者占６８．９％；体积为０－３０ｍｍ３者占７９．３％；严重盗血者占１９．７％；发现与颅内ＡＶＭ相关的动脉瘤占１６．９％；发现中央静脉引流及混合静脉引流者共５３．０％；有引流静脉狭窄者占８．２％。结论：颅内ＡＶＭ多位于表浅部位；体积多在０～３０ｍｍ~３之间；少数ＡＶＭ伴有相关动脉瘤和引流静脉狭窄；部分ＡＶＭ有严重盗血；一半以上有中央静脉引流，为选择治疗提供重要信息。
Objective: To investigate the morphological features of DSA of intracranial arteriovenous malformations (AVM). Materials and Methods: 183 cases of DSA with intracranial AVM diagnosed by IADSA were collected to analyze the morphological characteristics of intracranial AVM. Results: The superficial parts accounted for 68.9%; the volume was 0-30mm3 accounted for 79.3%; serious steal of the blood accounted for 19.7%; AVM-related aneurysms were found in 16.9%; found Central venous drainage and mixed venous drainage were 53.0%; with venous drainage stenosis accounted for 8.2%. Conclusion: The intracranial AVM mostly located in superficial parts; the volume is more than 0 ~ 30mm ~ 3; A few AVMs are associated with related aneurysms and drainage vein stenosis; some AVMs have severe steal; more than half have central venous drainage; Treatment provides important information.
